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.

Periphyton is enumerated by collecting a sample from alongside the canal at a depth of approximately 6" below the water surface. This sample was homogenized with deionized water and then enumerated by observing at 400X under a 40 micron field.

Slides are enumerated by taking all of the attached growth on a slide and homogenizing with 10 mL of deionized water. This is then enumerated using a Neubauer Improved hemacytometer. The amount of time each slide is in the canal is given.

All counts except Microcystis were performed by filtering 10 mL of sample through a 0.20 micron filter and all of the filtrate was identified and enumerated. Microcystis was enumerated using a Neubauer Improved Hemacytometer.

Periphyton is enumerated by collecting a sample from alongside the canal at a depth of approximately 6" below the water surface. This sample was homogenized with deionized water and then enumerated by observing at 400X under a 40 micron circular field. Results are an average of 4 separate counts.
