Big Lake South

Big Lake South State Recreation Area provides 127 acres of public access on the south shore of Big Lake, complementing facilities on the north shore to serve recreational demand on this popular Matanuska-Susitna Valley lake. The larger south site offers more extensive camping and day-use facilities. Big Lake's warm summer waters and proximity to Anchorage make it one of Southcentral Alaska's most popular destinations for boating, swimming, and family recreation.

The lake supports rainbow trout and landlocked salmon populations that provide recreational fishing. Waterfowl including loons and ducks utilize the lake during open water season. The more natural south shore provides somewhat better wildlife habitat than the developed north shore. Moose and bears occasionally pass through the area.

Boreal forest of birch, spruce, and aspen surrounds the recreation area, with some areas recovering from the 1996 wildfire. Shoreline vegetation provides limited fish habitat. Wetlands in the recreation area support sedges and moisture-tolerant plants. The relatively intact forest provides screening from development.

Big Lake occupies a glacial kettle lake basin characteristic of the Mat-Su Valley. The relatively shallow lake warms considerably during long summer days. Surrounding glacial deposits create the rolling terrain. The lake's closed basin retains the warmth that makes it popular for swimming.

Continental climate brings warm summers and cold winters to the Big Lake area. Summer temperatures frequently reach the 70s, warming the lake to pleasant swimming temperatures. Long summer daylight extends recreation opportunities. Winters bring ice fishing on the frozen lake.

The Big Lake area developed as a recreation and cabin destination following road access in the mid-20th century. Population growth in the Mat-Su Valley increased demand for lake access. The 1996 wildfire dramatically impacted the community but spurred rebuilding. Today Big Lake serves both recreational visitors and year-round residents.

The south recreation area was established to provide additional public access as private development increased around the lake. The larger site allows more extensive facilities than the north shore. Management coordinates between the two recreation areas. Facilities have been improved to meet growing demand.

Boating, swimming, and water sports attract the majority of visitors during summer. The campground provides a base for multi-day lake visits. Fishing for rainbow trout offers additional recreation. The natural setting on the south shore provides some escape from development.

The recreation area includes camping, a boat launch, swimming beach, and day-use facilities. Facilities have been improved in recent years. Access is via the Parks Highway and local roads from Wasilla. Commercial services are available in the Big Lake community.

Maintaining water quality in the heavily used lake requires ongoing attention. Septic system management helps protect lake health. The recreation area coordinates with other agencies on lake management. Fire recovery efforts continue following the 1996 burn.
