Middle Snake River at American Falls, ID

American Falls, Idaho

Snake River below American Falls Dam at American Falls, ID

The American Falls Dam is a concrete gravity-type dam located near the town of American Falls, Idaho, on river mile 714.7 of the Snake River. The dam and reservoir are a part of the Minidoka Project on the Snake River Plain and are used primarily for flood control, irrigation, and recreation.

American Falls was a landmark waterfall on the Snake River, named after a party of American trappers whose boat went over the falls. Birding in the American Falls area is excellent. With habitats such as marshes, lakes, ponds and riverine riparian the birder has much to choose from. American Falls is one of Idaho's most interesting birding areas with good birding year around. The Dam and cemetery overviews are good for viewing water birds and the local reservoir is excellent for shorebirds. The American Falls Reservoir has one of the highest concentrations of shorebirds in the state and is best visited in the fall for migratory species. The American Falls Fish Hatchery has a .75 mile nature and birding trail through Russian Olive trees along the Snake River.

MONITORING FREQUENCY

Middle Snake River at American Falls, ID is sampled from June 7th to August 30th

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.
