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 the year. This replacement is normal and necessary preventive maintenance. It is a proactive measure to maximize dam and public safety, and does not pose an imminent threat to surrounding homes.
Beginning in September, Waneka Lake will be slowly drained over three to four months 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 (CPW), the state agency that oversees fish management in Colorado, is working with the City to minimize impacts on the fish in Waneka Lake as it is drawn down. As a first step, CPW has approved a public fish salvage beginning September 9, 2015 which suspends bag and possession limits, allowing anglers to enjoy unlimited catches from the lake. This permission will be in place only during draining efforts and stipulates the following regulations;
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. Once the lake is refilled, CPW will begin the process of restocking fish species appropriate to Waneka Lake according to the management plan for this lake.
