Hangman (Latah) Creek
Hangman
Creek, also known as Latah Creek, is located in
Idaho and Washington with a drainage area of approximately
430,000 acres (260,000 acres in Washington). The watershed covers
a
significant portion of southern Spokane County, the northeast
corner of Whitman County, and portions of Benewah and Kootenai
Counties in Idaho.
Hangman Creek is by far the most critical
system in Spokane
County. It has 63 percent of its shorelines rated as FAR
(Functional-At-Risk) and is the only system that contains
any
nonfunctional river miles (3.3). Most of the FAR conditions
are
direct and indirect results of human influences
such as
agriculture, development, and encroachment on the shorelines
by
residences and road systems.
Although the system has the
lowest percentage of PFC (Properly
Functioning Condition) reach ratings in the County (30
percent), it
does contain a significant area of contiguous PFC extending
over
7.4 river miles in length. This area is a deeply eroded
basalt
canyon that is protected and impractical to most land
uses such as
agricultural production and residential development.
