Secchi Day on Beaver Lake is a FREE event scheduled for Saturday, August 19, 2017 from 9 am to 1 pm, hosted by Beaver Water District. Festivities will be at Prairie Creek on Beaver Lake, five miles east of Rogers, Arkansas on Highway 12.

There’s a Science Education Festival that includes activities for all ages! There will be a mobile aquarium, a scavenger hunt with prizes, free lunch and ice cream, test rides on kayaks and paddle boards, fun viewing critters under microscopes, and live music.

Secchi Day is also a time when an armada of volunteer citizen scientists gather water quality information from all over Beaver Lake. More than thirty groups of volunteers collect a water sample and measure secchi depth across the lake all in one day! They use a secchi disk to measure water clarity, or how deep into the water they can still see the secchi disk.

Secchi Day is meant to help inform people about water quality in Beaver Lake, which supplies drinking water to almost half a million people, or 1 in 7 people in Arkansas.
