Teton River

Tetonia, Idaho

The Teton River is an 81.5-mile-long (131.2 km) tributary of the Henrys Fork of the Snake River in southeastern Idaho. It drains through the Teton Valley along the west side of the Teton Range along the Idaho-Wyoming border at the eastern end of the Snake River Plain. Its location along the western flank of the Tetons provides the river with more rainfall than many other rivers of the region.

Some of the best fly fishing is found for both the beginner and the advanced angler in the Teton River.
Constant water temperatures provide excellent hatches for many fish species including Rainbow, Cutthroat, Cutt-bows, and Brook Trout. Technical whitewater in the Teton Narrows offers Class IV whitewater for kayakers.

SOURCE INFORMATION

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.
