Yay for Macroinvertebrates!!!

Today we went downstream of Woodcock Dam to check the water quality and chemistry in addition to searching for macroinvertebrates.  The diversity of macroinvertebrates signify how healthy a stream is.  We found some neat little critters.  There were a lot of cranefly larva, some water beetle larva, and there were even two small crayfish among other creatures.  There is then a system that assigns values to the different macros based on whether they live in healthy, fair, or poor water.  The value that we got told us that the water was of fair quality.  The tests for water quality also came back with pretty decent results.  We checked the temperature, pH, total dissolved solids, turbidity, dissolved oxygen, alkalinity, nitrates and phosphates.  Tonight we get to go hunt owls in a cemetery so wish us luck:)
