In Contra Costa County, when was the last time you spotted a species listed as “threatened” under the Endangered Species Act? Some, like the California Tiger Salamander and Red Legged Frog live in the wilder, more remote areas of the County. But there is one that migrates in and out of our urban cities, the Steelhead trout. Naturally, this species is tough to spot because it’s underwater. Yet, it survives, even with increasing pressure from urban environments, including migration barriers, habitat loss, and climate change.

However, the Contra Costa Resource Conservation District, in collaboration with numerous partners, including the East Bay Municipal Utility District, Caltrans, Contra Costa County Flood Control District, Friends of Pinole Creek Watershed, installed a fish ladder on Pinole Creek under the I80 freeway. A fish ladder is a designed and constructed restoration element that allows fish to travel upstream by providing resting areas of lower flow. Previously, trout were highly unlikely to be able to swim upstream against strong currents. The fish ladder has been successful for over 7 years by allowing Steelhead trout to migrate upstream to miles of critical habitat to breed, spawn, and continue their life cycle. How do we know? “Redds,” or trout nests, have been spotted upstream of the fish ladder.

Our local creeks represent some of the last parts of our urban areas that are suitable for a diversity of species to live, move, and thrive. The Steelhead trout is a species that needs a helping hand. Through the work of the CCRCD to restore and enhance local creeks, we are choosing to make a positive difference in the health of our watersheds and communities.
