Installing A New Dam - an update on the restoration at Silver Creek

Editor's note: The Kilpatrick Pond project is the largest enhancement project to take place at Silver Creek. The project is restoring the impounded section of the creek known as Kilpatrick Pond to address rising water temperatures and decades of sediment build up. Presently the pond contributes a significant amount of warm water into the system because of its large surface area. This affects over 15 miles of creek downstream. Every month we will post an update about the project on this blog.

We are nearing the end of the first phase of the restoration at Kilpatrick Pond. This month we completed dredging of the pond on the Purdy property, and began installing a new dam structure that is designed to allow for fish passage and the flow of cooler water under the dam. Recently water was diverted out of the pond to allow for the dam's installation. Fall is upon us and we are making steady progress. Stay tuned for more ...

Silver Creek diverted through Albrethson Ditch, an irrigation canal on the Purdy’s property. Diverting Silver Creek at this point exposes most of the pond sediment and allows for the construction of a new irrigation dam. Photo © Rydell Welch/TNC.
