Buffalo River

Island Park, Idaho

Buffalo River in Fremont County is 13.1 miles in length. At an elevation of 6,200 feet, the region around the Buffalo River is as interesting as the river itself. Island Park was created from a volcano that collapsed thousands of years ago. Now the area is covered with pine forests and lots of gorgeous wildflowers and has become a mecca of outdoor recreation the year round. Access to the Buffalo River is located approximately 27 miles north of Ashton and about 2 miles south of Island Park on US 20.

There is a boat ramp at the Island Park Ramp, so you can get your float trip going. Paddling down this river is peaceful and calming. Buffalo River is not far from the Island Park Reservoir, Island Park Dam, the Henry’s Fork of the Snake River, as well as the Big Springs Water Trail. Just below Island Park Reservoir, where the Buffalo River joins the Henry’s Fork, there’s an easy place to fish where you’ll find why this junction is famous for huge rainbows.

Buffalo River 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.
