TL;DR: In this paper, recent trends in key eutrophication-related properties, assess their likely ecological impacts, and develop load response curves to guide revised hypoxia-based loading targets called for in the 2012 Great Lakes Water Quality Agreement.

Spatial and temporal variation in phosphorus budgets for 24 watersheds in the Lake Erie and Lake Michigan basins
TL;DR: In this article, the authors estimated net anthropogenic phosphorus inputs (NAPI) to 18 Lake Michigan (LM) and 6 Lake Erie (LE) watersheds for 1974, 1978, 1982, 1987, and 1992.

Estimation of nitrogen inputs to catchments: comparison of methods and consequences for riverine export prediction
Haejin Han,J. David Allan +1 more
TL;DR: In this article, the authors compared the influence of various assumptions and computational details on the effectiveness of N input estimates in predicting riverine N export, compared eight separate net anthropogenic N input budgets and one soils compartment budget for each of 18 Lake Michigan catchments.

Historical pattern of phosphorus loading to Lake Erie watersheds
TL;DR: In this paper, the authors quantify trends in P loading to Lake Erie (LE) watersheds, estimating net anthropogenic phosphorus inputs (NAPI) to 18 LE watersheds for agricultural census years from 1935 to 2007.

Uneven rise in N inputs to the Lake Michigan Basin over the 20th century corresponds to agricultural and societal transitions
Haejin Han,J. David Allan +1 more
TL;DR: In this article, the authors document an uneven timeline of increase in anthropogenic nitrogen (N) inputs from 1880 to 2002 for watersheds that have undergone urbanization, intensive agricultural specialization or experienced minimal change, and find that the greatest increase occurred from 1950 to 1980, corresponding with rapidly accelerating use of artificial fertilizers.
