... documented that internal loading, resulting from sediment P release, may be a significant contributor of the total P input to some lakes. To assess the importance of internal loadings from sediments to Cootes Paradise, nutrient fluxes from sediments at three locations were estimated. The investigated sites...

The retention of phosphorus was negative from April until October, the most negative values generally occurring in May and July (–30% of external loading). In June, retention was less negative (−12%), probably influenced by clearwater phases...

...C.S. Reynolds; S.N. Reynolds; I.F. Munawar; M.

Most are oligotrophic. Many...
