 VALLEY DESCRIPTION Broad in the lower part, narrows above the forks and has a steeper 



gradient. Heavily forested. 

 DRAINAGE 52 square miles (polar plonimeter). Precipitation-fed. The E. fork is fed by numerous 



small lakes and ponds. The W. fork drains Anan Lake, 3 miles Icmg, and Boulder Lake, 



2 miles long. 

 STREAM MOUTH IDENTIFICATION Lies at the head of Humpback Bay. The stream enters a 



lagoon and the lagoon enters the bay through a constricted mouth. 

 ANCHORAGE Good anchorage is afforded in Humpback Bay or small cove on NE. shore of bay. 

 TRAILS AND SURVEY ROUTES A skiff may be taken into the lagoon at or near high tide and 



secured at the upper end. The skiff may also be left just E. of the mouth and a forest service trail, 



marked by a sign, followed upstream. The trail ends just above the old weir shack. A beaver dam is 



found 0. 7 mile above the hightidemark and a rough section of stream may be bypassed by going F, 



to the end of the pond and then S. through muskeg to the E. fork. The E. fork is easily waded. 

 AERIAL SURVEY NOTES Visibility is excellent in the E. fork. The W. fork has amber colored 



water.
