May 28, 2014 Water Monitoring Report

Great Day on the Lake/Rivers

For starters the weather was pretty good, not to too hot not too cold and the chop was not too bad.  The big news was a record breaking day in water clarity.  The in-lake average water clarity (Secchi depth) for today was 5.6 feet, the previous high was 4.5 feet, July 15, 2013.  Although probably very close to accurate, the true Secchi depth at the West Basin could not be determined because the disk was still visible while sitting on the bottom, 7.3 feet from the surface!  Water was not very clear on the Fox River with clarity only being 2.4 feet above the confluence with the Grand River


I suspect that there is little algae leaving the lake today as the water was not green and the water was filled with very large zooplankton, which are the most efficient feeders of algae in the water column.  The large zooplankton also provide great food for the tiny walleyes, yellow perch and other fry form this year’s hatch.

The bulrushes planted last year are growing very well so far, but are vulnerable to heavy waves.  

There are a few Common Terns are hanging around on the rafts, but no nesting yet.
