​Clear Lake North V-Notch Weir

At the upper end of the Watershed District, Clear Lake is the first lake the Clearwater River flows through. As part of the District's efforts to increase the water quality in this lake, a V-Notch Weir was installed on the northern tributary to the lake, near the public access. The purpose of this weir is to temporarily impound water during rain events over a 24-36 hour period. By doing so, this allows any water-born sediment a chance to settle out of the water column before entering Clear Lake. The project reduces phosphorus loading to Clear Lake by 575 lbs. annually, and provides wetland restoration benefits to 50 acres of drained wetlands.

Another notch weir is located on the southern tributary to Clear Lake. Learn more here.
