About

From Seboomook Dam, the West Branch Penobscot delivers three miles of commercial whitewater at flows averaging 2,690 CFS through an optimal range of 1,350–4,050. This privately managed section runs scheduled releases that paddlers track through USGS gauge 01042500. The concentrated gradient and heavy volume make this a destination for rafting outfitters working the controlled releases rather than natural snowmelt or rainfall patterns.
