Nine culverts over the nearly three-mile length of Crystal Springs Creek between SE 28th Avenue and the creek's confluence with Johnson Creek inhibit fish passage. Portland's Grey to Green initiative allocated money to replace eight of the culverts. In summer 2012, Environmental Services worked with TriMet's Portland to Milwaukie Light Rail Project and Union Pacific Railroad to replace the ninth culvert, which Union Pacific owns. The new 122-foot long railroad culvert is constructed to carry both Union Pacific trains and light rail trains over the creek. A grant from the East Multnomah Soil & Water Conservation District helped fund the project.
Crystal Springs Creek's cold water and consistent flow create ideal habitat for steelhead trout and Chinook and coho salmon. Removing barriers to fish passage and enhancing fish habitat aids Portland's endangered species recovery efforts.
