All counts except Microcystis and Oscillatoria were performed by filtering 10 ml of sample and examining the filtrate under 400X and the entire filtrate is identified and enumerated. Microcystis was enumerated using a Neubauer Improved Hemacytometer.

Periphyton is enumerated by taking a sample from the side of the canal at a depth of approximately 6". This is homogenized with deionized water and then 10mL is filtered through a 0.22 micron filter and then examined under an ocular reticule with a field of 0.0625 mm2 @ 400X (1mm2 @ 100X). Results are an average of 4 separate counts.
