Downstream of its source, the river is joined by meltwater from Matanuska Glacier in the northern Chugach Mountains . From there it continues through the Matanuska Valley, between the Chugach Mountains to the south and the Talkeetna Mountains to the north. Population centers along its course include Chickaloon , Sutton , Palmer , and Butte . It enters

Knakatnuk and Nitak (or Nitakh) were historic native villages on the arm's shore. The 1964 Alaska earthquake destroyed or significantly damaged most of the Anchorage neighborhoods adjacent to the Arm, including the downtown area. The proposed Knik Arm Bridge would measure approximately 2 miles (3.2 km) from Point MacKenzie on

The river is a popular destination for whitewater enthusiasts who float mainly in rafts or kayaks. Accessible at several bridges and other points along the Glenn Highway, the Matanuska varies from Class II (medium) to III (difficult) on the International Scale of River Difficulty . Expert paddlers sometimes run
198-523: The glacial braided river has damaged roads, farms, houses, and houses for decades. The United States Geological Survey operates a stream gauge near Palmer. Mean monthly discharge at this gauge varies from 500 cubic feet per second (14 m/s) in March to 13,000 cubic feet per second (370 m/s) in July. The maximum recorded flow was 82,100 cubic feet per second (2,320 m/s) on August 10, 1971, after
