2016 Map of Kateel River D-1 SW

About this map

The Koyukuk River dominates this landscape in the Yukon-Koyukuk region, winding through a complex network of wetlands and secondary waterways. This interior Alaskan environment is defined by its fluid geography, where the main river channel is flanked by significant bypasses such as Happy Slough, Tom Cook Slough, and Huntington Slough. These features indicate a dynamic floodplain where water levels and sediment shifts constantly reshape the land, creating landforms like Young Island. Isolated water bodies including Timber Lake and Whitefish Lake sit within the river's broad loops, marking the locations of former meanders or seasonal overflow basins. This 2016 survey provides a precise record of the river's path and the surrounding aquatic features in a region where road infrastructure is absent, making these waterways the primary arteries for travel and subsistence.
