An outlet valve at Waneka Lake, designed to control the release of water from the reservoir, is scheduled to be replaced by the end of 2015. This replacement is necessary preventive maintenance, and a proactive measure to maximize dam and public safety. The situation does not pose an imminent threat to surrounding homes.
Beginning in September, Waneka Lake will be slowly drained to expose this valve and allow for equipment replacement. The rate of water displacement will depend on demand and residential usage. Water will be diverted for use at the Indian Peaks Golf Course and treated for use in the City’s residential distribution system. Residents may notice a change in drinking water taste or odor during this time period, but the Lafayette water supply will continue to conform to all applicable Safe Drinking Water Act standards and water safety will not be compromised.
Colorado Parks and Wildlife is working with the City to minimize impacts on fish in Waneka Lake as it is drawn down. Beginning September 9, fish bag and possession regulations will be lifted to allow anglers to catch unlimited numbers of fish, through legal methods, from the lake during the drainage process.

Waneka Lake will be refilled upon completion of this repair. Depending on spring run-off and water rights, water levels are anticipated to be replenished sometime during the Spring of 2016.
