Lake Level Control Sub-Committee Meeting Minutes
November 13, 2013
Members present include Gil Kendrac, Dave Flaum, Dave Emick, Todd Gress, and Chairman Rick Gainar. Also present was RRA Board Member Dell Rogers.
Meeting called to order at 2PM at the Association Office.
1. Discussed the recent lake turnover event that occurred on or about 10/24/2013 and the subsequent algal bloom. O2 and temperature data collected on 10/4/2013, while the lake was still stratified, was compared to data collected after the lake turnover on 10/24/2013. Before the turnover temperatures ranged from 21.5ºC at the surface to 12.5ºC at 31-foot level while dissolved oxygen ranged from 10.4 mg/L to 0mg/L at the 17-foot level and below. After the lake turnover temperatures remained constant throughout the water column at 5.2ºC. Dissolved oxygen was also nearly constant ranging from 1.6 mg/L at the surface to 0mg.L at the 29-foot level.
2. Lake turnover is an annual event at Roam Rock Lake. So is the subsequent, massive algal bloom that follows this event after a few days time. The lake turnover event causes the phosphorus that was released from the organic sediment but held at the lake bottom all year, to mix in the entire water column.
3. We discussed the model siphon that a team of committee members recently installed at the dam using a length of garden hose. Dissolved oxygen data is currently being collected from lake water 5-feet off the bottom. Phosphorus data collection will soon follow.
4. No report from the Lowrey/Martin work group on their investigation of the water/sewage lines that cross a cove near the dam. We will need to understand the effect a freezing, winter drawdown would have on these lines.
5. A discussion ranking 13 advantages of a siphon spillway determined that the committee felt that less phosphorus & nutrients, improved weed control, and ability to maintain lake level for emergency repairs were among the most important. A siphon design with the ability to keep up with 100% of expected water flowing into the lake would be necessary.
Our next meeting is scheduled on December 11, 2013 at 2:00PM. Our regular meeting date is the 2nd Wednesday of each month at the Association Office so mark your calendars!

Lake Management Committee
by Richard D. Gainar, CEBS
August and September were very busy months for the Lake Management Committee (LMC). As you may remember, three sub-committees were created in August in order to 1) attract more residents so that work on several complicated subjects can be done simultaneously, and 2) take advantage of the many professional disciplines our residents have to offer. Significant attention will be paid to water quality on the Lake Sediment Control Sub-Committee and Lake Level Control Sub-Committee as well as to improving water depth in our back coves on the Lake Depth Control Sub-Committee. I am happy to report that a total of 19 residents are now working on the committees – a much larger number than the one or two member LMC’s of previous administrations. These committee members are from a variety of disciplines (including engineering, construction, biology, science, business, and many others) and are eager to work to improve our lake. Residents who are not able to attend these committee meetings can find each meeting’s minutes published on our web site and can direct any questions or concerns to the sub-committee chairmen at each Association meeting.
The Lake Sediment Committee worked to develop a methodology and a database to contain all professional collected information from previously commissioned studies and data in order to make good, evidence-based decisions. Their focus will be on excess nutrients and algae to start.
The Lake Level Control Committee decided to work on two projects in the coming months. The first involves creating a “model siphon” using a garden hose installed near the principal spillway in order to collect water samples from lake bottom. This project would allow samples to be tested all year, including through the ice, to obtain a full year’s data. This important data will provide evidence of the water’s chemistry before discharging from a siphon Spillway into the river below.
The Lake Depth Control Sub-Committee was busy designing a scoop-dredging rig we can use on the lake for many years. Already, two track hoes were recently purchased from available funds. In October’s meeting, the committee announced its plans for a 3-phased approach to dredging. Digging a basin to trap incoming sediment in the back of major coves is already underway. These sediment basins created in Phase #1 will be cleared on a regular basis. Phase #2 will begin this summer with the dredging of the channel in Fisherman’s Cove. There we expect to work the kinks out of our “scoop rig” operations (currently and successfully used at Lake Lakengrin) in Fisherman’s Cove before proceeding to the river channel in Rock Creek. All other coves river channels will follow the dredging of Rock Creek channel in order of need as defined in the 2010 EnviroScience Sediment Survey. This way, all cove residents will benefit from some improved depth before we move on to Phase #3 which involves returning to the larger coves in order to widen the area cleared in Phase #2.
In addition to the sub-committee meetings, our lake water testing program results were posted on the web site so residents can see the lab results. So far, the levels of various blue-green algal toxins were below any level of concern defined by the Ohio EPA.
Marty Hilovsky, our consultant from EnviroScience, on his second visit to our lake last month, met with our LMC leaders to discuss our lake management plans. He believes our program is “on the right path”. Marty tested the water’s clarity, sampled from various depths for algae toxins, phosphorus and other nutrients, and measured oxygen at various temperatures. These tests will be repeated by your Lake Management Committee and the results will be used by the various LMC sub-committees and for historic purposes.
Phase 1 Report:

Roaming Shores Lake Management Committee
2013 Algal Toxin Testing Program
Note: An orange warning sign will be posted at the beaches at 6.00 ppb.
Your Lake Management Committee is concerned with the unusual rash of erroneous information being disseminated concerning the levels algal toxins in our lake this year and cautions residents to be skeptical of information presented without supporting data. Your Lake Management Committee’s water testing program monitors water quality at our two beach areas during the hot, summer months and advises that all test results received so far have been well below any level of concern or alarm. The detailed results to date of this year’s algal toxin testing appears in the Lake Management section of the Association’s website (www.roamingshores.org). Should these test results approach the level of suspected danger, we will post caution signs at the beaches for your safety. Of course, common sense tells us not to swim in any waters that contain unusual amounts of algae. Please enjoy our beautiful lake and have a safe summer.
Members present include Bud Trarp, Dave Emick, Louise Lowery, Gil Kendrac, Sally Flash, Walt Samson, Dave Flaum, and Chairman Rick Gainar. Also present were RRA Board Members Del Rogers and John Martin.
Meeting called to order at 2PM at the Association Office.
- Advantages of a bottom-withdrawal siphon spillway including improved weed control, less algae and sediment, clearer water, improved fishery, less wear on the dam, less risk of blockage to the emergency drain port, flood mitigation measures, scheduled drawdowns, less phosphorus and other nutrients and methyl-mercury buildups. Disadvantages including impact on downstream waters and thermal instability were also discussed. This open-ended discussion included a basic description of how a siphon works and some of the issues involved in coordinating the project with Roaming Shores Village.
- Need to create a work group to investigate the water/sewage lines that cross the cove near the dam in order to understand the effect a winter drawdown would have on the lines. Louise Lowrey and John Martin volunteered to work on that project and report their finding to the committee.
- Need to create a work group to install a small 5/8” garden hose siphon near the principle spillway in order to begin sampling lake water from the approximate area in the lake where the actual siphon would draw water. A history of the water quality will be sampled and recorded. Rick Gainar and Dave Emick volunteered to initiate this project.
Members requested copies of the various lake studies and other background materials.
While meetings are regularly scheduled on the 2nd Wednesday of each month, conflicts required our next meeting to be rescheduled on September 25th at 2:00pm.
Meeting was adjourned at 3:45PM
Attendees: Barry O’Connell, Carolyn Tharp, Louise Lowrey, Rick Gainar, Rachel Morris, John Martin, Dell Rogers
Meeting started at 7:00pm at the RRA office.
Item 1. Introductions and back grounds of attendee’s experiences.
Item 2. All attendees expressed concern regarding level of nutrients and sediment coming into the lake.
- A discussion of the different studies and, their sources with the group strongly recommending that every source of information be evidence based and authoritative.
Item 3. The need to define a methodology that will lead us to a solution that best fits our lake sediment and nutrient loading issues was discussed.
- Suggested process / methodology for going forward.
- Create a data base of past and present relevant research related to sediment and nutrient loading of the lake.
- Identify appropriate local, state, and federal resources including Universities, nonprofit organizations, extension offices related to clean water.
- Identify sediment source
- Map and characterize sediment by analyzing
- Biological/Biochemical elements contributing to unacceptable lake conditions.
- Rachel Morris for her input and helping in defining the steps for our suggested process.
- Barry Oconnell for input and insight to pass studies and flow rates.
Next meeting is scheduled for Wednesday September 11, 2013 at 7:00pm RRA Office
Meeting ended at 8:30pm
Members present include Ron Morris, John Ball, Jim Schwartz, Mike Ritter, and Chairman Ed Baitt.
Meeting called to order at 7:30PM at the RRA Clubhouse.
1. Need to obtain a mechanical scoop-dredging rig similar in design to the one currently used at Lake Lakengren. The rig should be owned by the RRA since the ability to lower the lake level via a siphon spillway is still at least a year or more off and it will be used over the equipment’s lifetime. Use of this rig does not require the lake level to be lowered so dredging can begin as soon as it is in place. Other equipment can be used when the lake level can be controlled. The dredging rig would include 2 backhoes, 1 truck, 3 hopper barges, and 1 spud barge and would cost an estimated $200,000. Our own workboat can be used but will need a motor upgrade to a 60hp 4-stroke Mercury outboard motor. A bid was received and reviewed from B&R Construction, Inc. for building the spud barge.
2. The committee intends to dredge only the channel of each cove to allow property owners the ability they once had to boat to the main body of water. Accordingly, the committee will scoop out sediment from the channel near the back of several coves to learn how long it would take for the sediment to return. This may give us an idea of how often the coves channel would need to be dredged. RL50 and RL54 will be sample dredged first.
Meeting was adjourned at 9:15PM
No substances, materials or products intended or applied for the removal, treatment, or control of aquatic plants or animals, including, without limitation, chemicals and aquatic herbicides, shall be placed, or caused to be placed in the waters of Lake Roaming Rock without the prior approval of the Board of Directors, and such approval may be conditioned upon or subject to such reasonable terms and conditions as the Board of Directors deems appropriate.
Violators of this rule will be fined $1000.00.
MORE DREDGING INFORMATION AND PLAN PROGRESS
Well, summer is now only a memory, and the fall season is now at its mid-point. Your Board of Directors and Lake Management Committee, and many involved RRA members, have continued to work toward what will be the most significant, the most well-planned, and the most needed program in the 46 year history of our lake, a dredging program that will restore our lake’s water quality to what it was in the 1960s and 1970s.
This is the third in a series of Lake Management Committee reports to give our members as much information as possible about the dredging program currently being planned. In our first segment, we discussed why dredging is needed. Last month, we reported on a very productive and informative LMC meeting held in early September during which Tom Grabow, the ODNR Regional Dredge Supervisor of ODNR’s canal lakes region (northwest Ohio), told us about what the State of Ohio is doing to restore water quality at Grand Lake St. Marys.
But before we report on recent progress, let’s revisit the dredging clock. Like our Federal deficit, the clock is running. With the rains of the fall season, nutrient-rich sediment continues to flow into our lake. On average, since our last LMC article, another football field sized area was covered with new sediment to a depth of 1½ feet, smothering our lake bottom and continuing to feed nutrient-rich sediment into our precious lake’s ecosystem.
Recap of September 29th LMC meeting. Your LMC chair, and Board President Barry O’Connell, teamed up to present the powerpoint program given previously by Tom Grabow, and to provide detailed cost projections of the planned dredging program. About 15 to 20 members attended. The re-presentation of Tom’s program gave those in attendance who were not able to attend the first presentation, some insight into what the State of Ohio is doing to improve the water quality of Grand Lake St. Marys. The State has determined that there is no alternative to dredging, and they currently have three hydraulic dredges operating on that lake. The program will probably run indefinitely.
Despite some nay-sayers in our community, Tom made it crystal clear that the State’s position is that the only way to effectively address the problem is to remove the source of the nutrients that feed the blue-green algae, that being the sediment that has accumulated on the lake bottom. Let’s stop pretending otherwise and stick with the facts.
Finances. Those who are promoting the dredging program understand that the cost of the program is on everyone’s mind. Barry’s presentation presented an overview of the finances. The cash flow projections indicate that at the favorable interest rates that have been negotiated, the capital costs of the dredging program can be paid off over a 15 year time frame, and there are no plans to increase the current Lake Management assessment. If interest rates increase, the time required to pay back the principal will increase, but the annual payments will not. Thus, the assessment can be held constant.
The financial projections indicate that the capital cost will be around $1.3 million, and annual operating cost will be around $100,000. The target startup remains September, 2013.
Recent Trip to Ellicott Dredging. Three Board members, Barry O’Connell, Rick Rumbaugh, and Tim O’Donnell, took time out of their busy schedules to travel to Ellicott Dredging’s manufacturing facility in Wisconsin. They met with Ellicott personnel, observed the fabrication of hydraulic dredges similar to what the Association is planning to purchase, and discussed such details as support equipment, fusing of pipe, pumping rates, booster pumps, and other items.
It has recently become clear that we need to be able to pump sediment up to 7500 feet, maybe more, and that a booster pump will be needed. There seems to be no way to avoid the need to incorporate a booster pump into the planning process. It has also become evident that an 8 inch dredge seems to be the optimum size. Going to a larger diameter pump will increase cost, but not eliminate the need for a booster pump.
Engineering Firm Engaged. Chagrin Valley Engineering has been contracted to design the DMRAs, determine the best means to return the clarified water to our lake, and work through the permitting process with the US Army Corps of Engineers. The LMC chair, and Board President Barry O’Connell, recently met with CVE to discuss details of the design plans and agree upon a strategy to see to it that the program speeds its way through the design, review, and approval process.
The plan is to have designs submitted to the Corps around the end of the year, and to establish a project schedule that will have DMRAs constructed on the former Manzo property in the coming months. In the meantime, the Board is also investigating other properties further south that would provide the opportunity to begin dredging the south end of our lake sooner than would have seemed possible only a few months ago.
Once again I state that to those impacted by poor water quality (that’s any member who is paying attention); to those who have been choked by the growth of invasive and noxious weeds; and those who have seen their formerly lakefront property turned into swamp-front property, take heart, speak up loudly, support what we are doing, and don’t let those few nay-sayers drown out your voice for high quality lake water in all areas. Let’s continue to work toward returning Lake Roaming Rock to a condition that we can all enjoy without being concerned about aesthetic or health issues.
Lake Management Committee Chair
Over the next year The Lake Management committee will be writing monthly articles for the Shores News to provide our members with as much information as possible about the dredging program currently being investigated and implemented. We will discuss:
- Why dredging?
- The cost of dredging
- Recent progress
- How you can help
- Our current schedule
- Equipment to be purchased
- Schedule of Saturday morning meetings for open discussion
In these articles, we will try to touch on each of these topics, but concentrate monthly on more thoroughly explaining one subject.
This month we concentrate on why we need dredging, and also comment on some of the things that have been accomplished to-date, so dredging can begin in 2013. We know that:
- About 32,000 cubic yards of sediment, about 24,000 tons, flows into our lake every year, and there is nothing we can do to stop it. That’s like having about 1200 huge dump trucks dumping sediment into our lake yearly. To put it another way, this volume, if spread over a football field, would fill the field to a depth of 20 feet! In one year! Multiply that by 46 and you begin to get an idea of the problem we need to overcome. Can you imagine that? A football field 20 feet deep! Every year! This information was contained in a 1991 study and report by the U.S. Department of Agriculture authored by James N. Wade, a geologist. Knowing this, how can anyone who cares about our lake, which is the focal point of the entire Village of Roaming Shores, question what we are trying to accomplish?
- Over the last 35 years, the Association has engaged three environmental consultants to advise us on water quality issues – the last of which was EnviroScience, Inc. in 2005. The purpose of all of these studies was to evaluate the relative quality of our water , and advise us on what we can do to restore the water quality to that which existed when the lake was impounded in the mid-1960s. All of these studies warned us about the increased amount of accumulated sediment and the degradation of water quality caused by nutrients trapped in the sediment. These nutrients, mostly products that came into our lake from the local farmer’s fields, are harmful and promote the growth of algae which makes our lake water green when the water warms in the summer and becomes depleted of its dissolved oxygen.
- We have evaluated during the past 3 years alternative ways to remove the accumulated sediment and have concluded, with the help of experts in their field, (not laypersons, but experts), that hydraulic dredging is the most cost effective method of removing the sediment and eliminating our water quality problem.
Despite the negativity coming from some folks, the majority of the Board has concluded that most members who have any concern at all about our lake intuitively understand the problem we are facing and are tired of our doing nothing about the problems. Do they like the assessment? Of course not, but they understand that a small investment now will pay dividends in the future. Thus, the Board’s job is to keep the assessment as low as possible, and find other ways to help fund this project by continuing to reduce expenses elsewhere. The Board should be congratulated on the steps they have taken during the last year or so to reduce unnecessary expenses, streamline operations, and free up funds for dredging.
Now, is dredging the only answer? Do we have other tools in our toolbox? The answer is no, dredging is not the only answer, and yes, we have other tools. But we need to begin by removing the majority of the accumulated sediment. Then, after sediment is brought under control, we can consider installing aeration in some areas, and constructing a siphon to better control the water level during times of high inflow and allow us to lower the lake level when needed.
Folks, think of this as a financial investment that will pay you dividends in the future. It really doesn’t matter if you own property on the main lake, on a cove, or far from the water’s edge. For an assessment of $100 or less per year, less than $2 per week, we can return our water quality to what it once was. Think for a moment of the impact that will have on property values! Ask any of our local realtors about the difficulties they face in trying to market a property or home in an area of our lake that has excessive weed growth, green water, and not enough water depth to dock a boat. Sadly, some members have given up even trying to put a boat in the water, and have sold their boat, skis, and everything water-related because they don’t believe the Association will do anything to improve the situation.
So what we have accomplished recently?
- We have worked to strengthen our relationship with our environmental consultant, Enviroscience, keeping the lines of communication open with them and relying on their expertise on an ongoing basis.
- Concluded that after we remove what has already accumulated, we need to continue annual maintenance dredging to remove the estimated 24,000 tons of sediment that flows into our lake every year. That’s why doing the dredging with our own personnel and equipment makes sense, as the problem is never ending.
- Spent a day with ODNR officials at Grand Lake St Marys who already have three hydraulic dredges in operation to clean up that lake, and to observe their dredging program.
- Studied properties around our lake to seek out possible sites for sediment disposal and have reached agreement on the first of those properties.
- Attended meetings with US Army Corps of Engineers, and sought input concerning engineering companies they would recommend to assist us with our plans.
- Met with a recommended firm, and discussed with them the steps required to develop engineering drawings.
- Finalized conceptual details such as dredge size and output, discharge piping, means and methods, etc
- Developed proposals for the purchase of equipment.
We are doing what virtually every other lake in Ohio has done or is doing. We are not reinventing anything but following standard, proven procedures to restore and protect our Lake.
We will review the projected costs of this project and how it will be paid for in next month’s edition of the Shores News. We will also start informational meeting on weekends in the near future to review our progress with you and try to answer questions.
The Lake Management Committee will be having their next scheduled committee meeting on Thursday, September 13th at the clubhouse. We have invited Tom Grabow who is the western Regional Dredging Manager for ODNR to explain the projects he is currently working on. He is in charge of dredging three lakes in western Ohio, and has a wealth of information and experience to share. Please spread the word to all so that everyone who has questions or concerns can have an opportunity to listen to Tom and have their questions answered. The meeting will start at 6:30 PM.
We need your help and your support. We are planning a project that is unprecedented in the history of our Lake, but one that is much needed, and much overdue.
If you would like to offer your support to this project and become either an active or corresponding member of the Lake Management Committee, please e-mail me at Petraus@sme-usa.com. If you are not interested in supporting this endeavor, ask yourself what you plan to do with your home or property if in the future, our water quality continues to degrade and word gets out that our lake is not safe for swimming, tubing, or skiing and we are following in the footsteps of what happened to Grand Lake St Marys. What will you do when your kids or guests want to go swimming, tubing, or skiing, and you need to tell them that the water is not safe?
This is not about scare tactics, nor an exaggeration of facts. It’s reality folks, 46 years of neglect and wishful thinking. Think about it. And also think about how many people would choose to purchase property or a home in this area if the lake wasn’t safe or a third of it turned into a shallow swamp?
