The N:P mass ratios in the surface waters of Big Bear Lake indicate phosphorus limitation in winter and spring and nitrogen limitation in the fall. Algal assays confirm this pattern of nutrient limitation (Figure 11). In the spring, prior to stratification, phosphorus limited algal growth. Spikes of phosphorus in the algal assays resulted in significantly greater production than in controls (no nutrient additions) or those spiked with nitrogen or trace elements. In July, during stratifi- cation, phosphorus was limiting in the epilimnion and nitrogen in hypolimnetic.
