Memorial Day Weekend in the United States serves as the unofficial start to summer in the US, similar to Victoria Day weekend in Canada. People across the country are dusting off their lawn chairs, getting their pools open, and their boats on the water as the weather (and water) starts to warm up.

While many places in the southern US monitor year round, this weekend marks the start of most seasonal recreational water monitoring programs in the US. This goes for both regional governmental health units, which we work closely with here at Swim Guide, as well as local water quality organizations, including many Swim Guide Affiliates. Our incredible US Affiliates, (we have almost 60 of them!) work diligently in their watersheds to ensure their communities have access to reliable data about the waters they love and recreate in.

Most of our US affiliates run their own recreational water quality monitoring programs. Usually through a combination of staff, interns, and dedicated volunteers, they go out and collect water samples, process the samples at either a local lab or their own in-house lab, and then share the test results through Swim Guide. This vital work helps promote public health and safety, and keep citizens informed and connected with their local waters. Everyday we are inspired and encouraged by our affiliate organizations and the incredible work they do.

Below, we’ve together a handy list of all our current US affiliates, so you can learn more about them and swim sites they monitor We truly would not be where we are today if were not for our amazing affiliate organizations.
