Wildlife at Lake Twelve

Despite its water quality challenges, Lake Twelve remains a rich and vital habitat for wildlife. The lake and its shoreline support a remarkable variety of birds, mammals, fish, and other species — a testament to its ecological importance and a reminder of what we stand to protect.

River Otters

River otters (Lontra canadensis) are among the most delightful residents of Lake Twelve, often spotted lounging on the dock or slipping silently into the water. These playful, intelligent mammals require clean water and healthy fish populations to thrive — their continued presence is one of the most compelling reasons to restore the lake's water quality.

Great Blue Heron

The Great Blue Heron (Ardea herodias) is one of Lake Twelve's most iconic residents. These patient birds are a year-round presence at the lake's edge and a symbol of its continued ecological vitality.

Fish

Lake Twelve supports a recreational fishery enjoyed by anglers from across Black Diamond and beyond. For current stocking data, visit WDFW Fish Stocking.

Other Wildlife

The lake and surrounding vegetation provide habitat for ducks, kingfishers, osprey, beavers, frogs, turtles, and a wide variety of songbirds. The native riparian buffer plantings planned as part of the restoration project will further enhance wildlife habitat along the shoreline.
