Check out Field and Laboratory Methods for General Ecology, by James Brower
and Jerrold Zar (Wm. C. Brown Publ.).  As I recall (I no longer have the
book), there is a chapter on measuring productivity in aquatic ecosystems
(both micro and macro) that includes info on chlorophyll measurements.

Good luck!  (I'll look again to see if I can find the Brower and Zar book here)
