On of the Wood River Lakes, extends NW-SE 20 mi between Lake Nerka and lake Kulik, 45 mi N of Dillingham, Kilbuck-Kuskokwim Mountains.
Named for Beverley N. Polley, a prospector in the area in 1909-1910; published in 1912 by U.S. Geological Survey (USGS). This seems to be the same lake reported in 1910 by H.C. Fassett, U.S. Bureau of Fisheries (USBF), to have the Eskimo name "Cho-kwok-stchu-luk," which he reported to mean "pike here". It may be the "Lake Nushagak" of Ivan Petroff in the 1880 Census. See Takchik Lake.
