Swimming Locations & Water Quality Status

Swim Guide from Lake Pend Oreille Waterkeeper

Testing for safe swimming conditions near popular recreational areas

This swim guide shows a few of the popular swimming locations around Lake Pend Oreille. By clicking a location on our interactive map, you can see a description of the site and a link to the closest Water Quality Monitoring station. Our Water Quality Monitoring Program tests for 11 different physical, chemical, and biological parameters in 15 different locations around Lake Pend Oreille and the Pend Oreille River every month during the summer.

We have matched some of our favorite swimming holes around the lake with a nearby testing location so that you can see the water quality in that area! All listed sites have no known water quality issues. However, we only collect data 5 times a year per site and there may be current water quality issues that we are not aware of. Make sure check with the proper authorities about current conditions at recreational areas before you go!

What’s in the water?

What we test for & how it influences recreational water quality

Two of the major indicators for the safety of water quality in recreational sites are E. Coli and total chloriform bacteria. These measurements are very important to our high-use public access areas, such as Sandpoint’s City Beach.

LPOW generally finds very low concentrations of these indicator bacteria in our lake and river, which is great news for everyone who enjoys our swimming and recreation areas!

Since 2012, LPOW has partnered with the City of Sandpoint to establish and implement a new management program for aquatic invasive weeds without the use of herbicides. Thanks to this effort, Sandpoint beaches have remained herbicide-free and are safe to swim in!

Swim Safe!

Follow these tips to protect yourself in the water

1. Avoid entering the river with open cuts or wounds. Take caution to prevent infections and rinse off after swimming.

2. Beware of steep drop offs and fast currents. There can be dangerous drop offs near swimming locations and dangerous currents in the lake. Children should always be watched carefully.

3. Avoid industrial areas and discharge pipes. We test 15 different locations, but Lake Pend Oreille is the biggest lake in Idaho and you must use your own discretion to identify whether or not a swimming are is safe.

Report pollution if you see hazards in the water! Contact us so that we can continue to protect the safety of Lake Pend Oreille. Or contact the proper authorities who manage the recreational area for current information. We only test our stations once a month and collect no real-time data, so our data may not represent the current water quality status in the lake. In addition, we do not test directly at the sites listed above so there is a possibility of water quality hazards between our testing sites and recreational areas.
