Abstract: 

In situ relationships between nutrient avaliablity and algal production were investigated simutaneously in eight lakes of the Trent River drainage basin.  Three lakes were found to be oligotrophic, one-mesotrophic and four eutrophic.  No differences bewtweeen lakes were evident with respect to levels of total phosphorus, inorganic nitrogen, sulfate or iron.  Distinctions between lakes with respect to phytoplankton production were found to be directly related to alkalinity levels.  Additions of oxidized inorganic or biodegradable carbonaeceous material to a low alkalinity lake water were found to simulate algal production when sufficient nitrogen and phosphorus were present.
