Tradition Meets Innovation
The Stockdale Mill has worked well for the production of flour and corn meal since construction in 1856 however; the dam that provides waterpower to the mill turbine also hindered the ability of fish to migrate upstream. Nearly 80% of freshwater riverine fish species are migratory and rely on large stretches of river to complete their life cycle. The connectivity of stream habitat for spawning, rearing, and overwintering is critical to the health of fish populations within the Eel River ecosystem. Unfortunately, the study of fish passage as a whole has been devoted mainly to diadromous migratory fish (fish migrating between saltwater and freshwater on the Pacific and Atlantic coasts) and not to migratory freshwater fishes within Midwest streams like the Eel River. Due to the lack of research, blocked inland waterways by culverts and/or dams have been overlooked and highly misunderstood.
Fish Ladder Construction
The four-year effort to install this prototype fish ladder began after the Stockdale Mill Foundation gave their blessing to move forward with the project in 2013 as part of their
A partnership of biologists spent many years studying the fish populations in the Eel River while documenting how barriers affect fish migration. The Stockdale Mill dam provided a representative site that was the perfect location to test a one-of-a-kind fish passageway invented by B.K. Riverfish, LLC. Laboratory research and development of the fish ladder took place over a two-year period followed by a full-scale prototype constructed and delivered to the Stockdale site on. August 14, 2017. An antenna system to track the movement of fish within the river and fish ladder was installed in September 2017. The ladder was officially opened in mid-November 2017.
Since the installation and opening of the fish ladder, more than 15 fish species have been observed inside of the ladder. Fish as small as three inches have been documented to move through the ladder and around the dam. The first time fish could pass around the dam in 160 years! It is estimated fish as large as two feet will be able to swim up the ladder.
The fish ladder will be monitored to evaluate
It is estimated that 15 species of fish and thousands of individuals have passed through the ladder since its opening
