For 20 years, a road culvert blocked fish in Californias Sharber-Peckham Creek; crews replaced it in 2016, and 2017 monitoring found 740 juvenile coho upstream

In Northern California, a four-foot metal pipe had hindered salmon migration for two decades. After its replacement, juvenile coho salmon gained access to essential spawning habitats. This case underscores the critical situation of culverts obstructing fish passage nationwide. Recent research has identified the need to evaluate these structures for effective prioritization in upgrades. Continuous investment, study, and conservation efforts are essential for sustaining fish habitats.
