Title: Van Norden Dam Spillway Modification Project
Description: Note: Extended Review Per Led Truckee Donner Land Trust is proposing modifications to the dam spillway that would lower the spillway to allow unrestricted flow of water. The existing notch of the spillway would be lowered by 4.5 feet. The new spillway would be 48 feet wide and 95.4 feet long with concrete aprons on the upstream and downstream ends of the spillway. The new spillway would include a small incised channel 0.5 foot deep and 3 feet wide to allow water passage during low flow conditions in the summer and fall months. A 5 foot deep by 1.5 foot wide concrete wall would be placed below the modified spillway on the upstream portion of the spillway to prevent water seepage. Modification of the Van Norden spillway would require a Use Permit from the County of Nevada.
