Document - Clackamas River Hydroelectric Project: Whitewater Kayaking on the Oak Grove Fork


The Oak Grove Fork is a creek-like segment about 16 miles long. Hydroelectric development associated with the Clackamas Project (PGE) and the Stone Creek Project (EWEB) make the Oak Grove Fork a “bypass segment,” with most flow diverted into hydroelectric facilities. Only the five mile reach below Harriet Dam may offer interesting whitewater kayaking opportunities; the upper part of this reach drops about 185 feet per mile (with most of that gradient occurring in two falls), while the lower part of the reach drops between 50 and 120 feet per mile. Information about boating was developed from two primary sources: 1) hydrology information from PGE, and 2) interviews with boaters who ran the river during an October 2001 flow release of 300 cfs. Eight boaters in two groups ran segments below Harriet Dam during the study release.
