California Fish and Wildlife biologist Matt Lucero releases some of the 37 Sacramento Perch juveniles in Lindo Lake County Park in the Lakeside suburb of San Diego, Friday, August 11, 2023. Lucero brought the fish from Bridgeport reservoir, a picturesque body of water surrounded by snow-capped mountains that has become a bottleneck for the fish's genes because the isolated population cannot migrate.
