Lindsay Creek is a small watershed encompassing about 14,200 acres. It begins from springs at wetland just below Mann’s Reservoir and flows northwest joining the Clearwater River in Lewiston, Id. Creek elevation ranges from 1,800 feet at headwaters to about 750 feet near its confluence with the Clearwater River. The creek flows through farmland in the upper reaches toward a canyon before passing into a tunnel drain through the Clearwater Levee. Average precipitation in the Lindsay Creek watershed is about 12 inches.
Land use in the Lindsay Creek watershed is made up of mostly non-irrigated agriculture (72%) as well as small cattle operations, and a small suburban area in northeast Lewiston, Id.
Pollutants of concern include bacteria, nutrients, dissolved oxygen, and sediment. Stream temperature, flow alternation and habitat alteration also affect fish habitat.

The USDA Soil Survey for Lewis/Nez Perce counties was used to determine the extent of hydric soils within the watershed. Approximately 234 acres were identified and are illustrated in figure 2 (shown in light blue).
