Expansion of the Clackamas River Hydroelectric Project
A fourth new hydroelectric power plant is being constructed along the Clackamas River, uniquely different from the other three, and extensive updates to the Oak Grove Hydroelectric Project provide increased capacity. PGE also looked to reinvest in the community by providing camping and recreation opportunities along the Clackamas River, a program that continues as a core PGE commitment today.

North Fork Powerhouse & Reservoir
North Fork Hydroelectric Plant & Reservoir was completed on the Clackamas River. The dam is a concrete arched variable radius dam, thickness varies from 32 feet at the base to 8 feet at the crest with a 200-foot-long spillway. At a height of 206 feet, it is the tallest of the five arched concrete dams in Oregon.

PGE Parks & Recreation
PGE launched its extensive program to provide parks and recreational facilities near each of the hydro generating sites. Still loved today by millions of Oregonians, the parks program earned PGE its first Edison Award for leadership in developing parks and conserving natural resources around the dams.

North Fork Dam and Powerhouse
Frog Lake & Dam completed to expand capacity of the Oak Grove Hydro Project. Timothy Lake Lodge was constructed followed by Timothy Meadows Reservoir, later renamed Timothy Lake and Dam. Timothy Lake was created to provide a seasonal storage reservoir for all the PGE hydroelectric plants on the Clackamas. Water is released from the reservoir during months when lack of rain or freezing weather reduces natural stream flow to levels below peak operation. When Timothy Lake was completed, it was the largest water body in the Mount Hood National Forest.
