Timeline of major changes in lakes of the Yahara River Lake District, 1800 to present.
Annual phosphorus budgets for Lake Mendota, 1976-2008. Curves are annual load (g m-2 y-1) in red; mass of phosphorus in the lake (g m-2) on 1 November of the plotted year (solid green lines) and one year prior to the plotted year (dashed green lines) and phosphorus export through the Yahara River to Lake Monona (g m-2 y-1). Note low loads in the drought years of 1987-1988 and 2003, and high loads in the flood year of 1993. Over the 33 years of record there is no trend toward declining phosphorus inputs. However, the loads might be considerably higher if not for substantial interventions to control nonpoint pollution starting in 1998. The first decade of the 2000s brought a record number of large runoff events.
