DESCRIPTION:Environmental Engineering Graduate Seminar\n\nSusie Toivonen\, 
 Environmental Engineering Ph.D. student\, Michigan Technological Universit
 y\n\nAbstract:\n\nNutrients such as phosphorus and nitrogen cycle through 
 the environment naturally. However\, excessive nutrient concentrations hav
 e negative effects on aquatic ecosystems and water quality. While the impo
 rtance of good water quality has become more apparent over time\, and the 
 understanding of water quality protection strategies has improved\, nutrie
 nt loading continues to be a problem in many states\, including Wisconsin.
  As such\, this study aimed to support nutrient pollution management in Wi
 sconsin lakes. The objectives of the study were to (1) model a relationshi
 p between in-lake total phosphorus (TP) and water clarity\, (2) create a m
 odel that will measure lake sensitivity to phosphorus loading\, (3) determ
 ine which Wisconsin lakes are most and least sensitive to phosphorus loadi
 ng\, and (4) create a prioritized list for lake conservation/restoration e
 fforts based on lakes sensitivity to phosphorus loading. \n\nThis study us
 ed a quantitative approach to prioritize 929 Wisconsin lakes by sensitivit
 y to phosphorus. The model had three components: phosphorus loading sensit
 ivity (S)\, sensitivity significance (SS)\, and lake phosphorus sensitivit
 y significance priority score (LPSSn). A mass balance equation by Dillon a
 nd Rigler (1975) was used to determine sensitivity (S) to phosphorus loadi
 ng. Next\, the likelihood of reaching that phosphorus loading threshold wa
 s calculated using the sensitivity (S) and several other variables\, which
  gave the output SS. Finally\, SS was used along with clarity trend data t
 o determine a ranked lake phosphorus sensitivity significance (LPSSn) prio
 rity score from 0-100. Lakes near TP loading thresholds received a high LP
 SSn score\, while lakes that far exceeded TP loading thresholds scored low
 er. Lakes below TP loading thresholds were too few to report significant p
 lacement on the LPSSn priority score. Lakes in the Northern Lakes and Fore
 sts ecoregion scored significantly higher than the lakes in the Driftless 
 area\, Southeastern Wisconsin Till Plains\, and North Central Hardwood For
 ests. Model results will aid decision-makers in determining which waterbod
 ies should be prioritized for conservation and water quality protection. P
 rioritizing Wisconsin lakes based on sensitivity to phosphorus loading and
  then identifying significance of that sensitivity based on land use\, sur
 face area\, in-lake mean TP concentrations\, and other factors will target
  high-quality lakes near tipping points of becoming degraded.
