Comments: KWFRES_17_03 Site assessment information and photos collected and submitted by the Kenai Watershed Forum. Upstream and downstream have been ditched. Upstream channel runs along side railroad tracks for over a quarter mile before reaching source. Site is upstream from 49_2006 and a culvert that runs under the NAPA driveway. Sockeye and Dolly Varden Char caught upstream and downstream from site.
