Algal Counts performed by filtering 10 ml of sample and examining the filtrate under an ocular reticule with a field of 0.0625 mm2 @ 400X (1mm2 @ 100X). Results are an average of 6 separate counts.

Periphyton is enumerated by collecting a 5 mL sample from alongside the canal at a depth of approximately 6" below the water surface. This 5 mL sample was homogenized with 50 mL of deionized water and then enumerated using the above technique.

Slides are enumerated using the ocular reticule described above. The amount of time each slide is in the canal is given.

"F" = Cells or colonies enumerated by filtering 10 mL of sample through a 0.22 micron millipore filter and all of the filtrate counted and identified.

"H"= Those species too numerous to count using the above method. In these cases, a Neubauer Improved hemacytometer was used.

Slides are enumerated by taking all of the attached growth on a slide and homogenizing with 10 mL of deionized water. This is then filtered and enumerated using an ocular micrometer at a field of 40 microns at 400X.
