Beaver Lake Water Quality

blue and green wave

Secchi Day is an annual event that takes place on Beaver Lake with the goal of collecting important water quality data such as turbidity, chlorophyll-a, total phosphorous, and total nitrogen. On Secchi Day, volunteers take to the water to collect the lake’s maximum depth at which a Secchi disk can be viewed from the surface of the water which tells scientists how cloudy or “turbid” the water is. This valuable data has been collected for years and gives Beaver Water District a good idea of the water quality of Beaver Lake.

Secchi Day Gets a New 'Cooler' Feel

Each year, Secchi day data collection happens on the third Saturday in August, but the science festival is now combined with the Beaver Lake cleanup sponsored by the US Army Corps of Engineers into a new event called the Beaver Lake Volunteer Day. The new event celebrates all the ways individuals can volunteer to protect Beaver Lake and provides a new platform for the release of Secchi Day data that was collected in August. Now it is not just the Secchi disk depths announced but the water quality sampling results are provided too. Join us in October each year for the Beaver Lake Volunteer Day and talk to the District staff directly about the results.
