Five dams across California – including one in Lake County that forms Lake Pillsbury – have been listed as key for removal by an advocacy group in the effort to stop the extinction of native salmon and steelhead. In response to what it calls a “statewide fish extinction crisis,” which indicates 74 percent of California’s native salmon, steelhead and trout species are likely to be extinct in the next century, the fish and watershed conservation nonprofit organization California Trout on Tuesday released its list of the top five dams prime for removal in the golden state.
