The Potter Valley Project is a small hydropower project in the headwaters of the Eel River. It consists of two dams, a mile-long diversion tunnel, and a powerhouse with a 9.4 mw capacity. The project is located in the Eel River headwaters and diverts water out of the watershed into the Russian River. Removing this project is the necessary first step to fisheries recovery on the Eel River.
Traveling upriver as the salmon do, Cape Horn Dam is the first structure. It was built in 1908, stands 96ft tall, and impounds the river to make the 700af Van Arsdale Reservoir. Cape Horn Dam is equipped with a fish ladder, although some migrating species like Lamprey still have a hard time with this obstacle. About 12 miles upstream is Scott Dam. It was built in 1922, stands 138ft tall, and creates the roughly 79,000af Lake Pillsbury Reservoir. Scott Dam lacks any fish passage, preventing migrating salmonids and other native species from accessing roughly 10% of the Eel River Watershed.
Scott Dam impounds the river to form Lake Pillsbury Reservoir, all under the backdrop of Snow Mountain.
Cape Horn Dam impounds the Eel River to form Van Arsdale Reservoir. There is a fish ladder here where the Department of Fish and Wildlife conducts fish counts.
