River Description

The Morley Nelson Snake River Birds of Prey Natural Conservation Area, in southwest Idaho, was established in 1993 to protect a unique environment that supports one of the world's densest concentrations of nesting birds of prey. Falcons, eagles, hawks, and owls occur here in unique profusion and variety.  It is part of Bureau of Land Management's National Landscape Conservation System.

A float trip through is a great way to explore the unique surroundings of this section of the Snake River providing visitors a rare opportunity to observe golden eagles, prairie falcons, red-tailed hawks, and northern harriers in their natural environment. More than 800 pairs of raptors, including 15 different species nest in the area. Canoeing or rafting on the Snake River is an ideal way to view raptors and explore the canyon.

The 10 mile section from Swan Falls Dam to Celebration Park is a popular day trip or you can continue on down another 5 miles to the bridge which has a good boat ramp. Depending on the river flows and how many stops you make along the way, plan between two and four hours to float the first 10 mile section. The river is generally flat water but there are two Class II rapids in this stretch and it is not recommended for beginning canoeist. Operations of the Swan Falls Hydroelectric Project (FERC Project No. 503) affect flow on this reach. Despite these fluctuations the river has plenty of flow to enjoy throughout the year. This section is floatable year round. Flows range from 3,000 cfs in the winter to 40,000 cfs in the spring.
