Algae Treatment Scheduled for August 21
Lake Treatment Aug 21
By D.Ernes – Lake Management Committee
Since the last algae treatment, we have experienced a massive storm system that dropped significant rain, caused gale force winds and knocked out power, internet and in some cases cell service to a portion of our community. We have some recent data that shows that this event also had a significant impact on the water quality and conditions of the lake, especially in the northern end. This may be the cause of the bloom reports made by residents, our consultants, and the LMC team since that event.
While lake conditions can vary from day-to-day, after an evaluation of all available information, a decision was made to implement another algae treatment, this time in the northern half of the lake where most of the reports have been received and the water quality was most significantly impacted. Scheduling a treatment involves many moving parts and can not be done at moments notice. While there may be some disruptions, we have tried to minimize them.
In the meantime, it is necessary to repeat a statement that is made with every weekly testing summary, at most Board meetings, and in several articles.
AVOID DIRECT CONTACT WITH AN ACTIVE BLOOM.
This is especially important for the young, those with compromised health conditions, and even your pets, who can not read this warning.
The following steps will be done. *Please note that, should these plans change, we will let you know as soon as possible.
1) The lake level will be monitored and, if necessary, the lake will be lowered.
2) Please turn off all fountains or other devices that agitate the lake water north of Sugar Creek on Wednesday, August 21. They may be turned back on Friday morning, August 23.
3) Please refrain from any activities on the lake, including boating, jet skis, etc., starting Wednesday, August 21 to allow the treatment to be effective and to spread in a predictable manner. All activities may resume on the morning of Friday, August 23.
4) While the lake is deemed safe following the application, we are closing the beaches on Wednesday morning, August 21 as a precautionary measure. Swimming and other activities involving direct contact with the lake should be avoided during this time. While unlikely, if you observe any undisposed product (a powder with a bluish tint), avoid direct contact and let the office know where it is observed. Normal activities can resume on Friday, August 23.
5) Do not water your property with water from the lake during this 48-hour period.
Lake Management Update – After Treatment Comments
By D.Ernes – Lake Management Committee
This past Thursday, we completed the treatment of about half of the lake, from the south to around Beach 1. This treatment was needed as a result of an increase in the severity and intensity of blue-green algae in the southern end of the lake. The treatment area was adjusted from the original announcement due to the concern of further spread of the affected area due to around an inch of rain over a 48-hour period. The lake is a dynamic environment that can change by the hour, day or week and we need to respond accordingly.
There were reports of boat activity during the 48 hours following the treatment. This product is imbedded in a binder that allows it to float on the surface of the water for a time before it sinks, where it become bound in the lake sediment. The product is applied by trained individuals so that it can be spread by the currents in the lake, as well as the wind. Boat traffic during this period would push the product in an unpredictable manner. This could negatively impact the success of the treatment. In the future, please follow the restrictions so that we have the best chance for success.
Lake Treatment Scheduled
Update: The treatment was applied as planned on 8/1. Please no boating or swimming on the lake until Saturday morning. Thank you for your cooperation in helping our treatments be effective!
The southern area of the lake has seen an increased frequency of algal blooms over the past week. After discussions with our experts, we are scheduling a partial lake treatment for this week, as outlined below. The problem area does not include the entire southern half, so we are evaluating a partial treatment. We hope that by using this targeted approach, we may be able to do future treatments in localized areas. It is unknown if this will as effective, but it has great upside potential if it works. And it is fully expected to address the bloom in the southern end of the lake.
Flame Lake will be evaluated on Thursday and will be treated if warranted.
LAKE TREATMENT SCHEDULED FOR THURSDAY, AUGUST 1.
The following steps will be done. *Please note that with the weather predictions for this week, should these plans change, we will let you know as soon as possible.
1) The lake level will not need to be lowered as the drought has taken care of that for us.
2) Please turn off all fountains or other devices that agitate the lake water south of Sugar Creek on Thursday, August 1. They may be turned back on Saturday, August 3.
3) Please refrain from any activities on the lake, including boating, jet skis, etc, starting Thursday, August 1 to allow the treatment to be effective and to spread in a predictable manner. All activities may resume on the morning of Saturday , August 3.
4) While the lake is deemed safe following the application, we are closing the beaches on Thursday morning, August 1 as a precautionary measure. Swimming and other activities involving direct contact with the lake should be avoided during this time. While unlikely, if you observe any undisposed product (a powder with a bluish tint), avoid direct contact and let the office know where it is observed. Normal activities can resume on Saturday.
5) Do not water your property with water from the lake during this period.
As always, since the rest of the lake will not be treated at this time, please avoid direct contact with any active algal blooms.
Lake Treatment Scheduled 6/19
Update: Treatment went ahead as planned on 6/19. Please no boat traffic, water fountains, or lake swimming until Friday. Your cooperation helps the treatments be more effective. Thank you!
Lake Treatment Scheduled for
Wednesday, June 19th
This year, we implemented two new programs – enhanced monitoring of the lake using a handheld probe, and evaluation of ultrasonic buoys. The former measures key parameters including algal densities. The latter is a non-chemical means to limit algal growth and was implemented in key spots on the lake.
The probe data showed an increase in algal densities over the past few weeks. This culminated in a visible bloom observed at the southern end of the lake around Fisherman’s Cove. The weather forecast anticipates excessive temperatures, which is likely to accelerate the bloom formation. After discussions with our consultants, we are scheduling the first half of a whole lake algal treatment using VodaGuard C for Wednesday, June 19. This will include the southern half of the lake. Because of the on-going evaluation of the ultrasonic buoys, we will NOT be treating within the effective range of the buoys, which includes the area around Spanish Cove and Sugar Creek (near Beach 2). We will closely monitor these areas.
The following steps will be done during the first treatment. *Please note that should these plans change, we will let you know as soon as possible.
1) The lake level will be lowered to comply with the Ohio EPA requirements for this application. The valve is expected to be opened on or about Monday, June 17 sufficient to lower the lake level below the spillway. Please adjust your boat tie downs to accommodate the water level change.
2) Please turn off all fountains or other devices that agitate the lake water in the application area on Wednesday, June 19. They may be turned back on Friday, June 21.
3) The application will be applied during the day of Wednesday, June 19.
4) Please refrain from any activities on the lake, including boating, jet skis, etc, starting Wednesday, June 19 to allow the treatment to be effective and to spread in a predictable manner. Boat traffic may resume on the morning of Friday, June 21st. The boat ramp will be closed during this time period.
5) While the lake is deemed safe following the application, we are closing the beaches on Wednesday morning, June 19 as a precautionary measure. Swimming and other activities involving direct contact with the lake should be avoided during this time. While unlikely, if you observe any undisposed product (a powder with a bluish tint), avoid direct contact and let the office know where it is observed. Normal activities can resume on Friday.
6) Do not water your property with water from the lake during this period.
As always, since the northern half of the lake will not be treated at this time, please avoid direct contact with any active algal blooms.
Lake Management Plan Update
By D.Ernes – Lake Management Committee
As we move into the recreational season, we have begun to implement several of the programs for this year. If all goes well, the ultrasonic buoys should be in place at five locations on the lake. These buoys are being evaluated as a non-chemical means of controlling the algae blooms. It will take some time for them to begin to control the algae, but we have high hopes that they will be effective. As has been discussed, please avoid them as you move about the lake. The success of this approach hinges on each boater avoiding these devices.
The second program which has started is the use of the water quality probe. With this hand-held device, we can monitor parameters to help assess the health of the lake. With the ability of measuring algal densities, we hope to be better able to assess treatment timing and location, as well as monitor effectiveness of the ultrasonic buoys.
One thing to note with these programs is that they are all being driven by RRA members. The buoys will be deployed and maintained by our maintenance department. The water quality probe data collection is being done by volunteer members of the Lake Management Committee who spend several hours on the lake gathering data. We have also had LMC volunteers managing the goose deterrent program by addling eggs in their nests.
As was discussed at the Annual Meeting, each of us can help to keep our main asset in good conditions. Complying with the boating rules especially with No Wake areas will help reduce nutrients from being introduced from boat wakes. Proper lawn maintenance can do the same for controlling nutrient runoff. Other practices have been mentioned. Everyone working together can go a long way to …

Ultrasonic Buoy Deployment Notice
By D.Ernes – Lake Management Committee
At the March and April meetings, it was announced that part of the 2024 Lake Management Plan will be the evaluation of ultrasonic buoys. These buoys use solar panels to power ultrasonic emitters that are suspended in the water. The sound waves disrupt the ability of blue-green algae to rise to the surface, depriving them of the sunlight they need to survive. As a result, they will die and drop to the bottom of the lake. This is a non-chemical alternative to the algaecides we have employed for the past few years and have been shown to be safe to non-target organisms.
The presence of these buoys (about the size of a 50 inch television set) can become an object that boaters will need to be on the look out for. The picture at the right shows what these buoys look like. They are equipped with a US Coast Guard approved flashing beacon for nighttime navigation assistance.
There will be five of these positioned throughout the lake, primarily adjacent to No Wake Zones. We expect that they will be deployed in the next few weeks, in time for the Memorial Day weekend, and the anticipation of high boat traffic volume. Please use every effort to avoid coming in proximity to these buoys. They are expensive to replace. In addition, the lead time for a replacement is about a month, so if they are damaged, that area of the lake will not have any protection from the growth of blue-green algae.
The location for these buoys is as follows:
- At the dam near the no wake area
- Mouth of Plum and Sugar Creeks at the start of the No Wake Zone
- In the Southern end of the lake below the No Wake buoys near Spanish Cove and about a 1000 feet further north.
We need to have these buoys in place for the entire recreational season to evaluate their effectiveness. If we can show that that they work, we can substantially reduce our reliance on chemicals. Thank you for your vigilance.
Lake Management Best Practices: Lawn Maintenance
By D.Ernes – Lake Management Committee
We are slowly transitioning from winter to spring. Our lawns are also transitioning from the dormant state, where it is an off shade of brown, into the lush green we all want to enjoy. The important thing we each need to realize is that if we are not careful, our efforts to get a green lawn will contribute to us experiencing a green lake.
Grass, and blue-green algae, both need phosphorus to grow. For our lawns, phosphorous may be introduced as a component of fertilizers. But is it necessary? An inexpensive soil test will be a good idea before you apply any fertilizer. It is possible that if the pH of the soil is out of balance, it can inhibit the grasses’ ability to absorb nutrients. If this is the case, it could lead to over fertilizing and the excess nutrient will just end up in the lake after rain events.
Luckily, over time, most commercial fertilizers have reduced or eliminated the level of phosphorous that is in their products. If one looks at the bags, the three numbers appearing on each bag is the level of Nitrogen-Phosphorous-Potassium. So, it is best to select products where the middle number is zero.
There have been a lot of articles stating that, for established lawns, it is not always necessary to add phosphorous to our lawns. This is especially true if one mulches the grass clippings, which returns the phosphorous the grass already contains back into the soil.
There may be a need to use phosphorous when first establishing a lawn. In this case, the use of Starter Fertilizers may come into play. Make sure that you do NOT select this type of product for an established lawn. Even when using Starter Fertilizers, an inexpensive soil test will let you know if it is even necessary. Also, when applying this or any fertilizer, proper application techniques (avoiding over spraying on impervious surfaces, and not applying it up to the waters edge) will help to reduce the likelihood of excess phosphorous in the lake.
When mowing your lawn, the best option is to mulch the grass clipping back into the lawn. If this is not desired, do not blow the clippings into the street or, more importantly, into the lake. The latter can incur a fine. If you see your neighbor or a lawn service employee discharging clippings (or debris for that matter) into the lake, talk to them and encourage them to use another approach. Use the compost site which is the best location for your yard waste.
These suggestions are valid whether you live on the lake or off. Our community is roughly 1500 acres. And we are the closest part of the watershed to the lake. If we all do our part, it will have an impact of the lake. Remember that every ounce of phosphorous that you add to the lake can cost hundreds or thousands of dollars to eliminate. If you use a commercial company to handle the lawn treatments or maintenance, make sure that they follow practices to reduce their impact on our lake.

Geese Addling Program
By Gerry Dixon -Lake Management Committee
A successful Canada Geese control program is an essential part of lake management. Data collected over the last five years with the reduction of the geese population and lower bacteria at the beaches, suggest that our program is successful. The population if uncontrolled could become epidemic. Geese mate for life and return each year to the same location to nest. Their lifespan can be up to thirty years and the offspring return to the same location each year. Two geese typically have six eggs per year and the babies have six eggs for up to twenty years. If uncontrolled the rate of population growth in 4 years is thirty-six geese, in 8 years 1,296 geese, in 12 years 1,679,616 geese, and in 16 years, 2.8 trillion geese.
Each goose can consume up to four pounds of grass per day, creating about two pounds of fecal matter daily. During June and July, they lose their flight feathers, and during this time each goose produces 122 pounds of feces, in 16 years at the rate of population, 341trillion pounds of droppings can end up in our lake. This obviously not realistic, but it does show the impact on a community. According to Ohio Geese Control, “These droppings can be a health risk and can carry Salmonella spp., E. coli, and Listeria spp. And large flocks of geese can alter the ecology of your pond and create algae problems.”
Good news: there are natural enemies that control the geese population. Bad news: these natural enemies are not normally found in our lakefront community. Therefore, a geese control program is needed in our community. Roaming Shores has successfully reduced the population through implementation of Ohio Revised Code section 1531.02. in partnership with the Ohio Department of Natural Resources.
The aim of the Lake Management Committee is to observe, preserve, and correct any lake problems. The geese control program is part of the Lake Management Committee objective to decrease the amount of nutrients and bacteria entering our lake. Previously, when this program was first implemented up to thirty nests were seen. Last year 13 nests were invalidated.
With the help of all lake owners, the Rome Rock Association is tracking all observed nests and recording actions taken. Please call the association at (440) 563-3170 or email the association at IT@roamingshores.org if you see any Canada geese nests. Please be informed, it is a federal crime to injure, move, or harm without the permission of the Division of Wildlife any bird or nest.
Help us to be Lake Responsible.
Report Goose Nests
To maintain a safe environment and ensure our lake is safe for all members, please inform the association via email or calling 440-563-3170 of any nesting birds. In this manner, we can deter the proliferation of Canada Geese from Lake Roaming Rock. The population of geese if maintained through the Ohio Natural Resource Goose Damage Permitting System, works to keep the overpopulation from occurring.
The Ohio Natural Resources (ONR) writes, “Most people will welcome and start feeding the first pair of geese on their pond, but these geese will soon wear out their welcome. In just a few years, a pair of geese can easily become 50 to 100 birds. The feces will foul the areas around the pond and surrounding yards and damage the lawn, pond and other vegetation. Geese that are fed will lose their fear of humans and attack adults, children, and pets during the nesting season (March through June). DO NOT FEED GEESE. Feeding bread, corn, potato chips, popcorn and other human food items harms the geese and sets the scene for goose attacks on people.”
Ohio State University also writes “Degraded Water Quality – Large accumulations of feces near water can degrade water quality as rain wash the material into the water. Goose feces are high in phosphorus and nitrogen, nutrients that in excess can cause nuisance blooms of algae and aquatic plants in ponds and lakes. An excess of algae and submerged plants can lead to oxygen depletion at night due to plant respiration and can cause a fish kill.
In addition, goose feces can contain a variety of pathogens such as Giardia and Coliform bacteria, which can cause illness in humans. Large numbers of geese can elevate concentrations of these pathogens in pond and lake water, and accidental ingestion of such water can cause illness”.
With your help and ONR, we have used the Goose Damage Permitting System method for the past years and have found it works. Reductions in population, nest counts, and returning migrations are examples we realized. I encourage all our residents to continue with this effort and their notifications are important to our overall effort to keep our lake safe and healthy!

Overview of Recreational Season for 2023
By David Ernes – Lake Management Committee
The 2023 season turned out to be a season of unusual weather coupled with unexpected observations. Despite this, for the third straight year, we ended the season with no algal toxin levels exceeding the EPA Advisory limit. We also added over 400 pounds of feeder fish to enhance the excellent fishery. This document includes a review of the issues we faced and the conclusions from the reports from our consultants.
The report from EnviroScience related to the in-lake conditions found that, on a whole lake basis, the algaecide treatments were successful at maintaining the recreational use of the lake. Selected areas did observe issues but overall, the lake has seen an improvement since 2021. In August, algae populations increased primarily in the north, which was surprising, prompting the second partial algaecide treatment. The nitrogen levels were elevated above that seen in prior years. The report does encourage efforts being done to control the nutrients by seeking financial assistance.
The AquaDoc report, measuring the conditions south of the lake, showed phosphorus levels similar to last year. The increase in nitrogen levels primarily for nitrate, appeared at the end of June and originated in Whetstone Creek. It appeared as the weather shifted from a drought to heavy rain events. It slowly returned to normal as the summer progressed. While the source is unknown, the elevated nitrogen level is felt to be responsible for some of the unusual observations this season.
Throughout the course of the year, we have been in communication with our consultants to try to understand the unusual situations we experienced. The consensus opinions are briefly described below.
Filamentous Algal Mats. As has been discussed both at Board Meetings and e-blasts, an increase in non-toxic green, filamentous algae is expected as we work to control the more toxic blue-green algae. In addition, the increase in nitrogen (in the form of nitrates) entering the lake likely acted as a ‘fertilizer’ for the filamentous algae, increasing the magnitude of the problem, especially in the south.
Floating snails. At the end of June, an increased number of floating snails were observed. These snails, likely Mystery Snails, are invasive to our area. They seemed to originate in the south (observations in September found them to proliferate south of the lake) with the shells floating north with the current. The complicating factor is that these snails can float and still be alive. Observations by our consultants and the author have confirmed this. While there are several possibilities to explain why they behaved as they did, it is not clear which factor (or some combination of factors) was responsible. The fact that this was unique to this season suggests the nitrate level increase as a likely contributing factor.
Odor in the South. Around September 22, a sewer-like odor was observed in the south end of the lake, extending upstream of the bridge. This was found to be due to a condition called hypoxia, where the oxygen level in the lake was depleted. When this happens, odor-causing chemicals are released as the aquatic vegetation and algae die off at that time of year, consuming dissolved oxygen in the water. Normally the fall rain brings in freshly oxygenated water, but the unusually dry September prevented this, so the normal processes occurring in the lake were again disturbed. In addition, the high level of filamentous algae, and the excessive vegetation in the lake below Spanish Cove and extending south of the Route 6 bridge added to the load. This drop in oxygen also adversely affected the fish (and snail) population in this area. With artificial aeration and returning rainfall, the situation was corrected.
Overall, this year we saw that factors beyond our control acted against our efforts to improve conditions in the lake. Until we find a Bond villain with a weather control machine, we will have to do our best to adapt. As in the past, we will use lessons learned this season to direct our plans moving forward. Because, as always, we all must do our best to…
