We placed 12 islands that are approximately 4'x5' (kidney shaped) on a 3.5 acre pond that has a high nutrient load. The pond was also treated with alum to tie up excess nutrients.

Water tests were done prior to get a baseline of nutrient levels, then again after the alum treatment. Water tests will be done annually to track how different things are working.

Some other things that have been done or are in the works is a 2nd liquid alum treatment and a bacteria treatment.

Over 400 native plant species (Indiana natives) were used on the islands. Geese are banned from the pond........
