Secchi Day

Volunteer teams gathered at different points on the lake to take part in the first Beaver Lake Secchi Day.
Michael Clark and his son Bernie were among the volunteers.
"I think helping the Beaver Water District, educating my son and being on the lake, it just seemed like a great recipe for a good day," Clark said.
The Clarks measured the water`s clarity at two places on the lake by using a secchi disk-- a weighted device with alternating black and white quadrants.
The tester lowers the disk into the water until it disappears from sight...the disk is attached to a rope divided into meters. The depth in which the disk is no longer visible determines the water`s transparency.
Teams were also asked to collect water samples from their locations. Once all the results are in, the Beaver Water District will record the secchi measurements in it`s database.
Audubon Arkansas and the Beaver Water District sponsored the event.
