   Lumen Charter High School students got their hands dirty as they toured Green Lake’s watershed and ended their afternoon conducting experiments at Avalon Creek Farm, on the south side of Green Lake by Markesan.

   The group ventured out May 16 with their teachers and representatives of the Green Lake Association, touring Mitchell Glen, watching carp harvesting by the County Road K marsh and then conducting water tests.

   The tests ranged from analyzing the amount of dissolved oxygen in the creek water to listing the organisms found in the stream’s bed. Based on the organisms discovered, the students could determine how polluted the water may be since some organisms can live in heavily polluted water while others may be more sensitive.

   Students also checked water clarity, temperature and water flow.
