North Fork Reservoir, Reservoir in Clackamas County, Oregon, United States

North Fork Reservoir is an impoundment on the North Fork of the Clackamas River located in the foothills seven miles south of Estacada. The cold, clear water is surrounded by narrow, steep canyons with trees lining the banks, serving both power generation and outdoor recreation purposes.

North Fork Dam was built in 1958 on the Clackamas River, five miles upriver from Estacada, creating the reservoir behind it. Portland General Electric operates this dam together with the nearby River Mill and Faraday dams. The reservoir takes its name from the North Fork of the Clackamas that flows into it.

The reservoir is named after the North Fork of the Clackamas River and has long served the local community as a place for outdoor recreation. Families and groups come to paddle, fish, and spend time together on the water, making it a social gathering place for people from nearby cities.

North Fork Reservoir lies five miles upriver from Estacada, reached by road along the Clackamas River; Portland General Electric operates the dam and the nearby River Mill and Faraday facilities. The reservoir sits at 666 feet (203 m) elevation and covers about 0.58 square kilometres, stretching roughly 1.6 km north to south and 2.1 km east to west. Boating and fishing are the main activities on the water.

A smaller water body called Small Fry Lake within Promontory Park is designed specifically for young anglers, allowing children up to 13 years old to catch three fish per day. This sheltered spot offers families and beginners a safe place to learn fishing.
