Wood River Drainage
The Wood River basin has
a drainage area of over 2,990 square miles. Major drainages in the Wood River
system are the Big Wood and Little Wood rivers. At its lower end, the Big Wood
River is also known as Malad River. Flows from the Wood River drainage are controlled
for irrigation and flood control by four major reservoirs: Magic, Little Wood
River, Fish Creek, and Mormon. Approximately 144,000 acres are irrigated from
reservoir storage and other diversions. Recent hydroelectric power developments
are currently in operation at Magic Dam, Little Wood River Dam, the confluence
of the Big Wood and Little Wood rivers, the Little Wood near Shoshone, and the
Malad River dams. Additional hydropower facilities are proposed for the Malad
River near the Malad Gorge State Park.
This drainage contains
the most productive trout streams, lake, and reservoir habitat in south central
Idaho. Nearly all the major rivers, streams, lakes, reservoirs, and ponds
are suitable for trout.
Good populations of
warmwater game fish are found in many waters of the Wood River drainage, mainly
in reservoirs, lakes, and ponds. The principal warmwater fish species present
are yellow perch, largemouth and smallmouth bass, and bluegill.
There are 16 alpine lakes
which support fish in this drainage. These lakes are all relatively productive.
