Takshanuk Watershed Council conducted comprehensive fish distribution studies of the Upper Chilkoot River watershed above Chilkoot Lake. These studies were funded by the U.S. Fish and Wildlife Service and the Alaska Sustainable Salmon Fund during the spring, summer and fall seasons of 2008-2011. Minnow traps, dip nets and visual observations were used to identify fish species present, rearing and spawning in the Upper Chilkoot. The studies resulted in streams being nominated for the Anadramous Waters Catalog (AWC). In addition, a more detailed description of the fish species observed were added to the AWC.
These maps show land ownership, anadramous streams (green lines) and the Glory Hole Road (dashed black line), as well as locations for species of fish. Fish distribution sites are coded for species and life stage. The species are: Coho (CO), Sockeye (S), Chum (CH), Pink (P) and Dolly Varden (DV). Species codes are in capital letters. Lower case letters indicate if the fish observed were present (p), rearing (r) or spawning (s).
Coho, Dolly Varden and Sockeye were observed along the entire length of Upper Chilkoot. Pink and Chum were observed at the lower reach of the Upper Chilkoot.

Initial Road Condition Survey Maps
These maps are the result of an initial survey, not a formal engineering survey. The definitions for good, fair, poor and roadbed as stream are below.
Good- roadbed intact and wide enough to permit use of road with minimal refurbishment. Characterized by small particle size- sand and clay fractions integrated into surface layer. In general these sections were relatively flat and not crossed by watercourses
Fair- some erosion of the roadbed. Small size fraction missing, at least in part, from road surface. Road shows some evidence of runoff having removed some soil. Mild gullying may be present. Roadbed may be somewhat narrowed as well.
Poor- road clearly shows effects of erosion- clay to small gravel fraction largely removed and significant gullying. Road surface both rough and uneven. In steep side-slope sections the roadbed has narrowed significantly.
Severely damaged (Roadbed as Stream)- These sections were either submerged during the survey or showed very severe damage due to large amounts of runoff. The submerged sections were inundated due to flooding upstream of beaver dams, by changes in natural drainage patterns in the valley or by large streams having been captured by the roadbed and running along it. Note also that many of these sections are now included in anadromous waters catalogue by virtue of their running through fish habitat polygons.
