Blackfoot Reservoir, located in southeastern Idaho, covers 18,000 surface acres when full, making it the second largest reservoir in the region. The main dam stands 55 feet high above the streambed, with a usable storage capacity of 413,000 acre-feet at maximum water surface elevation of 6,124 feet.

While primarily used for irrigation, Blackfoot Reservoir offers numerous recreational opportunities for paddlers. The lake features a boat ramp for easy access. Paddlers should be aware that the reservoir is also popular for motorized boating.

The reservoir is home to a diverse ecosystem. Its islands provide habitat for pelicans, cormorants, and gulls, while the waters attract various waterfowl and shorebirds. This makes the reservoir an excellent destination for birdwatching enthusiasts. The lake also boasts a healthy population of rainbow and cutthroat trout, as well as carp, offering opportunities for fishing from kayaks or canoes.

Facilities at the Blackfoot Reservoir Campground, managed by the Bureau of Land Management, include picnic tables, fire rings, vault toilets, drinking water, and an accessible fishing trail. The campground offers 16 developed campsites and 12 semi-developed sites, all available on a first-come, first-served basis. This provides convenient overnight options for multi-day paddling trips.

Paddlers should note that there are fees associated with both day use ($5 per vehicle per day) and camping ($10 per night for developed sites, $5 for semi-developed). The campground may close during winter months due to snow, suggesting that late spring through early fall might be the optimal paddling season.

The reservoir's large size offers ample exploration opportunities. Paddlers should exercise caution and be prepared for changing weather conditions, given the reservoir's expansive surface area.
