Marin salmon runs extend farther with help from rain
Surveyors of Marin County’s endangered coho salmon had something to celebrate this year after heavy downpours allowed fish to access habitats where they haven’t been seen in nearly two decades. … Marin County has the largest population of Central Coast endangered coho salmon from Monterey Bay to the Sonoma-Mendocino county line. Once believed to number in the tens of thousands, coho salmon in Marin have dwindled to the hundreds. The decline is largely attributed to habitat loss caused by land-use changes and development such as dams, which blocked access to about half of the salmon’s historic habitat and caused creeks to fill in with more sediment.
