Potlatch River

Spalding, Idaho
Mis à jour par Snake River Waterkeeper

SWIMMING IS UNADVISABLE DUE TO HIGH WATER LEVELS AND UNSAFE RUNOFF

The Potlatch River is about 56 miles (90 km) long, it is the lowermost major tributary to the Clearwater River, a tributary of the Snake River that is in turn a tributary of the Columbia River. Once surrounded by arid grasslands of the Columbia Plateau adjacent to the western foothills of the Rocky Mountains, the Potlatch today is used mainly for agriculture and irrigation purposes. This watershed is characterized by steep basaltic canyons in the lower reaches, and timbered hills in the upper reaches.

The Hoodoo Mountains are the source of the Potlatch River. Hiking and camping are popular recreational activities on the river; 14 percent the watershed lies on public lands. Many of the mountainous and forested sections of the drainage basin lie protected under national forest lands. There are several campgrounds overseen by the U.S. Forest Service in the headwaters of the Potlatch River watershed. Anglers are only permitted to catch brook trout, cutthroat trout, and rainbow and steelhead trout. The Department of Fish and Game annually stocks fish in the river.

SOURCES

There is currently very limited water quality monitoring of Idaho's inland swim sites. The federal Beach Act does not cover freshwater or riverine beaches, and states in the Basin do not monitor Snake River swimming beaches or recreational access sites.

As part of its Water Quality Program, Snake River Waterkeeper monitors water quality at more than 100 sites on the Snake River and its tributaries for temperature, dissolved oxygen, pH, salinity/conductivity/total dissolved solids, ammonia, and nitrates. Data are collected at sample sites June-October and assigned safety ratings based on comparison to EPA's Recreational Water Quality Criteria for Human Health:

pH: 5 – 9 µg/L
Salinity/Conductivity/Total Dissolved Solids: 500 mg/L
Nitrates: 10 mg/L

A site is marked Green when single sample results meet all Human Health Criteria.
A site is marked Red when the results are equal to or above Human Health Criteria.
A site is marked Grey when there are no current results or no available information.
Sites found to exceed EPA's Aquatic Health Criteria are noted in site descriptions.

While criteria measured are useful indicators of contamination, there are many other potential sources of pollution that are not reflected in our Swim Guide, including E.coli and other bacteria, heavy metals, pharmaceuticals, fertilizers, and pesticides that harm aquatic life.
