name meaning "sandy river" published by the Russian Hydrog. Dept. as "R Sushitna," meaning Sushitna River, on Chart 1378 dated 1847. The Susitna River appears to have been first explored in 1834, by a "Creole named Malakov", and the name may have been obtained by the Russians at that time. The present spelling of the name has evolved due to euphemistic reasons.
Description
The Susitna River heads at Susitna Glacier, in Alaska Range, flows southwest to Cook Inlet, west of Anchorage, Alaska Cook Inlet Low. There are several rivers flowing into the Susitna River including East ForkSusitna River and West ForkSusitna River. The Little Susitna River is a separate river system which flows into the Cook Inlet on the other side of Susitna Flats. The Susitna along with the Matanuska River, drains the broad Matanuska-Susitna Valley south of the Alaska Range. It rises in the Susitna Glacier on Mount Hayes in the Alaska Range near. It flows in winding course generally southwest to Curry, then south, along the west side of the Talkeetna Mountains, past Talkeetna, Chulitna River, and Susitna, and drains into Cook Inlet approximately 25 miles west of Anchorage. It receives the Yentna River from the northwest approximately 5 miles north of Susitna. It is navigable to 85 mile upstream from its mouth to Talkeetna. Valdez Creek, notable for its 1903 gold mining, is one of the small headwater tributaries of Susitna River. The Susitna River is one of Southcentral Alaska's premier sport fishing streams, with significant runs of Chinook and Coho salmon, along with resident grayling, burbot, and rainbow trout. Located within a roadless area, access to the river is difficult and is made usually by power boat or by floatplane. crosses the upper Susitna river Matanuska-Susitna Borough owns much of the land along the Susitna and Deshka Rivers. The impacts of summer recreational use and tourists have caused loss of riparian vegetation and bank erosion along the Deshka River's lower reaches, which has been partially remedied through a restoration project in the summer of 2002. However, the borough currently lacks either regulations to prevent further damage or the means to enforce such regulations.
Susitna River is on the North side of Cook Inlet North-East of North Foreland. Mount Susitna, a prominent landmark along the upper part of the inlet, is about West of the Susitna River at a point above the mouth. The channels across the flats at the mouth of Susitna River have depths of or less at low water and change during the winter and spring because of ice and freshet action. The channels above the mouth are said to change frequently in the spring and early summer. Launches navigate Susitna River to Yentna River, about above Cook Inlet, thence run occasionally up the Yentna River to the forks about from the Susitna River. The tides are not felt more than from the inlet, and above this the current is swift. Overhead power cables with a least clearance of cross the Susitna River about above its mouth. Alexander, Alaska is a small settlement on the west side of Susitna River above the mouth. Susitna, Alaska is on the East side above the mouth and just below the mouth of the Yentna River; launches run to and from Anchorage, Alaska. Mail is delivered to both settlements twice monthly by airplane from Anchorage, Alaska. Susitna Flats lie between big Susitna River and Little Susitna River and to the East of the latter. Susitna Flats Light, above the water, is shown from a skeleton tower and is equipped with a racon. Little Susitna River, West of Point MacKenzie, is said to be navigable for landing craft and skiffs at high water for about. The depths offshore and in the approach to Little Susitna River are subject to drastic and continual change.
Bridges
The Susitna River Bridge is a railroad bridge of the Alaska Railroad in south-central Alaska. It spans the Susitna River on the eastern edge of Denali State Park near Gold Creek. The bridge is on the National Register of Historic Places. Construction of the bridge took place from October 1920 to February 1921. The span is 503 ft., with a height of 71 ft. in the center; the steel weighs 2,000 tons, and rests on two concrete piers, each 50 ft. high and 70 x 40 ft. in cross-section, and each containing 1,500 cubic yards of concrete. The location was chosen, just downstream of a curve, after observing the pattern of ice jams through the preceding three years.
Ice
Between approximately October 19 and November 14 the Susitna River ices or freezes over for the winter. Between April 12 and May 10 the ice breaks-up for the summer.
