Comments: Site submitted by HB Jeanette Alas from her May 2016 trip to Atka. Culvert has been permitted to be replaced with a 48 inch diameter culvert. Fish Habitat Permit FH 16-II-0074. Road is eroding on the downstream side and the bottom of the culvert outlet is perched about 22 inched. Corrosion has damaged the pipe so water is exiting before invert. No trapping at site, but locals did say that the pink salmon use the lower reaches of this stream.
