Project: Dennett Dam Removal

Description: The Project will remove Dennett Dam, an abandoned low-head dam located on the lower Tuolumne River in Modesto, California. Dennett Dam is a stressor to Fall-run Chinook salmon and Central Valley steelhead, causing a partial barrier to fish passage while also contributing to warmer temperatures and creating habitat for predator species.

Reference Number: 3600BP1696040

Implemented By: Tuolumne River Preservation Trust

Objective: Objectives are to: improve upstream passage for fish, the primary focus being steelhead trout (Oncorhynchus mykiss) and chinook salmon (O. tshawytscha); provide unimpeded access to 36 miles of Tuolumne River above Dennett Dam; improve rearing habitat and downstream passage for juvenile anadromous fish; reduce non-native predatory fish habitat; and restore more natural geomorphic and ecological processes.
