Trout ‘trapped’ in Arroyo Seco. Study advocates removing barriers
Removing man-made barriers in a major tributary of the Los Angeles River could provide a lifeline for native trout — most, if not all, of which were rescued from a destructive 2020 fire — according to a new report. A presentation of the findings last week by environmental consultant Stillwater Sciences called for taking out three impediments in a stretch of the Arroyo Seco that restrict the movement of the trout, potentially cutting them off from spawning areas or refuge from drought. The nonprofit Arroyo Seco Foundation commissioned the research as part of a multiyear project to improve the flow of the winding creek and benefit an endangered species of trout.
