Beginning this Saturday, Aug. 15, the public is invited to participate in the first-ever Online Virtual Secchi Day Science Fair with videos and photos of Environmental and Water Education activities. Visit Beaver Water District’s website at http://www.bwdh2o.org to get started. Provide us with feedback and win a prize! A Secchi disk is a black and white device lowered into the water to measure clarity. Sampling activities and the education fair, led by Beaver Water District since 2006, rely on partners and citizen volunteers. The data collected helps BWD monitor the quality of the water in Beaver Lake, the water supply for half a million people. To ensure everyone’s safety, the Secchi Day Science Fair is virtual this year.
