Book Description
Saskatchewan's Fishing Lakes, the primary recreation lakes for residents of Regina, are plagued by immense blooms of algae throughout the summer. The algae thrive on high concentrations of nutrients, particularly phosphorus. The dynamics of phosphorus in lakes are normally controlled by water renewal rates and sedimentation. In this report, the theory of phosphorus dynamics was extended to include a chain of lakes like the Fishing Lakes. A model was developed based on the water renewal or outflow time scale, the sedimentation time scale, and the water inflow time scale. The dynamic variation of phosphorus in the Fishing Lakes from 1980-83 was then simulated using the phosphorus inflow concentrations measured every 3 days by WQB and the daily water flows as input data. A second simulation was run using the sparse data set that was available for phosphorus inflow from 1970-79. The calculated outputs were directly compared with the measured outflow concentrations.

Book Description
The phosphorus loading concept is examined within the framework of equilibrium input-output models. Some theoretical and practical shortcomings of several phosphorus models are then discussed. Finally, the dynamics of total phosphorus in lakes is explored using first-order linear theory with time-dependent coefficients.
