Middle Subbasin Overview
The Middle Subbasin drains approximately 78 square miles of the Van Duzen Basin containing predominantly Douglas-fir dominated forests with grassland and mixed harwood forests composing most of the remaining vegetation. Virtually all the land in this subbasin (98.5%) is privately owned. Primary land use includes timber production, cattle ranching and rural residential developments. The Middle Subbasin is very sparsely populated and contains only one small town for the entire subbasin. Bridgeville, located along the Van Duzen River near river mile (RM) 31, provides a school, post office and a community center for residents who live in outlying areas. The Van Duzen River and the Middle Subbasin tributary streams support populations of Chinook salmon and steelhead. Coho salmon have been reported to spawn in Middle Subbasin streams, but due to the lack of focused surveys and overall population decline coho have not been documented in the subbasin since the early 1980s (Reynolds et. al 1981 and Decker and Fuller 1984). Chinook and coho salmon are unable to migrate upstream of Salmon Falls at RM 37, and the end of anadromy for steelhead is at Eaton Falls, RM 46.3 (just beyond the designated border of the Middle Subbasin).
