The 13th annual Secchi Day event is set for Saturday, Aug. 18 at Beaver Lake.
The water appreciation science festival is organized by Beaver Water District, and includes volunteers equipped with Secchi disks, which are devices that are lowered into the lake to measure the transparency or clarity of the water. The volunteers collect samples on their own boats, and bring them back to be recorded.
Over time, the measurements are an indicator of the water quality in the lake, which serves as the water source for one in seven Arkansans.
Volunteer teams will return from various locations around the lake from 9 a.m. to 1 p.m. During this time the public is invited to Prairie Creek Recreational Area (9300 N. Park Road in Rogers) to enjoy free exhibits, educational activities, boat tours, and lunch.
This year’s activities will include a kayak giveaway and kayak test rides, snacks, live music, children’s instrument making and free coloring books. Those in attendance can also make a water testing device to take home.
