Lake Depth Improvement Sub-Committee Meeting Minutes – June 18, 2013
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
