Upper Subbasin Overview
The Upper Subbasin includes the watershed area along the Eel River from Barber Creek to Dean Creek at the town of Rio Dell, a distance of 7.5 miles. It also includes the Van Duzen River from its mouth to Cummings Creek, approximately 9 miles above its confluence with the Eel River. There are 21 named tributaries and 64.3 permanent stream miles in this subbasin. This assessment area encompasses the upper delta agricultural lands. Stream elevations range from approximately 40 feet at the confluence of the Eel River with Barber Creek to approximately 2,160 feet in the headwaters of the tributaries. This subbasin is the largest of the Lower Eel Basin at 75 square miles, 43% of the total basin area. This subbasin is mostly held in private parcels 40-500 acres in size with some sections owned by large timber companies and managed for timber production. Chinook, coho, steelhead, and Coastal cutthroat trout have each been documented in fish surveys of the Upper Subbasin.
