The public is invited to attend the 11th annual Secchi Day on Beaver Lake from 9 a.m. to 1 p.m. on Saturday, Aug. 20, 2016, at Prairie Creek on Beaver Lake, five miles east of Rogers, Arkansas, on Hwy. 12. The Final Schedule has been set! The Science Education Festival includes activities for all ages, with a mobile aquarium, on shore scavenger hunt with prizes, free lunch and ice cream, kayak test rides, microscope activities, a photo contest and more. This event is free. Email

The event is named for the Secchi Disk, a black and white device lowered into the water to measure clarity. Volunteers with boats help us gather samples that day. This takes about 20-30 minutes, but there’s travel time involved depending on where your sample point is located. Pre-registration well in advance is necessary. So this year’s registration for the sampling activity is already closed. However, if you are interested in being put on the list for notification to potential teams for the 2017 event, send an email to Sabrina Bowman at
