A growing beaver population in the South Bay may become a problem for efforts to increase salmon in the area.
The South Bay Clean Creeks Coalition is keeping a hopeful eye on the Guadalupe River in San Jose, where beavers are making themselves at home and working to build dams.
The dams are starting to partially block waterways at a time when local salmon are ready to spwan.
Beaver dams can help spawning salmon because they aid in the creation of wetlands and provide shelter for baby salmon. But excessive silt caused by the dams can create issues in areas where the salmon lay their eggs.
The coalition is asking the Santa Clara Valley Water District to try to find a solution that allows both the salmon and beavers to coexist.
