| Abstract: | During the Spring of 1972 through the Spring of 1973 samples of rivers tributary to Lake Ontario and streams in the Genesee River Basin (New York) were analyzed for N and P forms by chemical methods, then incubated in darkness or bioassayed with algae to estimate the percentage of total N, organic N, total P or particulate P which could eventually become available for algal growth in Lake Ontario. The total available P in the river water samples could be estimated by adding to the soluble orthophosphate 0.2 of the difference between the soluble orthophosphate and the total phosphate. The total available N can be estimated from the sum of the inorganic N (NH3 and NO3 ?) plus 0.5 times the total organic N concentration |
