Lake Level Control Sub-Committee Meeting Minutes – August 14, 2013

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.

Items discussed:

1. 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.
2. 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.
3. 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 2^nd Wednesday of each month, conflicts required our next meeting to be rescheduled on September 25^th at 2:00pm.

Meeting was adjourned at 3:45PM
