[ General Watershed Information ] [ Little Susitna Watershed ] [ Cottonwood Creek Watershed ]
From jumping and
spilling
over rocks with
water the blue of glaciers, the Little Susitna River begins from the Mint
Glacier at Hatcher Pass in the Talkeetna Mountains and flows 113 river miles to
empty into Cook Inlet. Along the
way, the Little Susitna matures from the fast flow ing glacial river to being
slower and wider with gravel and riffle areas near Wasilla and
Houston. By the time the Little Susitna reaches Cook Inlet it is wide and
meandering with many switchbacks and is affected by tidal action. The water has lost its blue
tint to browns.
The habitat areas have changed also from spruce and birch riparian areas
to large expanses of wetlands. The
Little Susitna watershed helps control flood waters, filters pollutants,
supports recreation, and is a scenic landscape.
The
Little Susitna is home to runs of Alaska’s five salmon species (Coho, Chinook,
Sockeye, Chum, and Pink) and its river habitat holds essential spawning grounds.
According to Alaska Department of Fish & Game, the Little Susitna is
one of Southcentral’s most-fished streams. It is second only to the Kenai River in number of Coho caught.
Needless to say, the high level of use has had some negative effects on
the river with stream bank and habitat degradation.
The
Little Susitna flows through the heart of the Mat-Su Borough, which since 1990
has seen the population base
grow by approximately 16,000 people, a 42% increase. According to the Alaska Department of Labor, the Mat-Su Borough is
Alaska’s fastest growing population center. In many instances, development has been rapid and land use planning
efforts have been narrowly focused and have not addressed resource
sustainability. This could
obviously have devastating effects to the Little Susitna and to the local
economy.
