Chesterfield Reservoir

**Location & Basics**
Chesterfield Reservoir (also called Portneuf Reservoir) is located near Bancroft in Caribou County, Idaho. This 1,245-acre reservoir on the Portneuf River offers a developed boat ramp for launching kayaks, canoes, and motorboats. Idaho Fish and Game has maintained the access site with a ramp and installed docks to facilitate angler and paddler access to the water.

**What to Expect**
The reservoir provides a relatively calm water environment suitable for recreational paddling, fishing, and boating. Given the lake setting, this is a good option for paddlers seeking flatwater conditions rather than river current. The area is located in Idaho's southeastern mountains, near other recreational opportunities along the Portneuf River system and nearby camping areas managed by the BLM and Idaho Fish and Game.

**Planning Your Visit**
Before heading out, check current conditions and access status with Idaho Fish and Game, as access sites can experience seasonal closures. The nearby Lower Portneuf River campground offers overnight facilities for those planning extended trips in the area. This location works well as a base for exploring the broader Portneuf River recreation corridor.
