SAYLORVILLE LAKE
Mathangwane, B. T. (2001). Seasonal variation of lake water quality : influence of colloidal suspended solids and water chemistry in selected Iowa lakes.
This project focused on the chemistry of lake-water and lake-sediments with respect to their potential to carry inorganic and organic phosphate, ammoniacal nitrogen, as well as nutrient dispensability in lake-water, causing turbidity, due to seasonal fluctuations in lake-water chemistry. Lake-water and bottom-lake sediments were obtained from four Iowa lakes: Big Creek, Laverne, Little Wall and Saylorville. The selected lake-waters were expected to experience different types and sources of inputs due to differences in management of surrounding watersheds. Results showed changes in chemical composition of lake-water as seasons progressed from mid-summer to mid-fall and, that lake-eutrophication depended on lake-water chemistry, and epilimnetic TN:TP ratios as dictated by dispersion/flocculation processes. Mineral nitrogen was mostly in the NHb4 s'confined' form, and P0b4s-P was mostly in the inorganic form.
In order to shed additional light on the quantity-form and potential release or bioavailability of NHb4p+ sand P0b4s-P, quantity-intensity (Q/I) studies were carried out. Data suggested that in two of the lakes (Big Creek and Saylorville), a P-adsorption mechanism was operative, whereas the other two lakes (Laverne and Little Wall), some form of metal-phosphate was in effect. However, all four lakes showed that P would not be a limiting nutrient. Data further suggested that variation in suspended solids between lakes, which can be attributed to land management practices might influence water chemistry. The relatively high pH and phosphate presence along with the smectitic/humic coated clay minerals of Iowa and dissolved solids suggested high-suspended solids potential.

Kahler Royer, C. A. (1999). A water quality index devised for the Des Moines River in central Iowa.
A water quality index was derived for the Des Moines River in central Iowa. The Des Moines Water Quality Index (DMRWQI) was based on the National Sanitation Foundation's Water Quality Index (NSFWQI). This index is intended to give the general public a better idea of the state of the water quality in the Des Moines River, with sampling stations beginning near Boone, Iowa, and continuing to immediately below the Lake Red Rock dam near Pella, Iowa. A sampling station on the Raccoon River at Van Meter, Iowa, is also included. The Des Moines River Water Quality Index examines dissolved oxygen saturation, pH, biochemical oxygen demand, nitrate and nitrite nitrogen, un-ionized ammonia nitrogen, turbidity and suspended solids for sampling stations along the Des Moines and Raccoon Rivers and on Saylorville and Red Rock Lakes.
Rating curves are used to rank parameter values, and these rankings are aggregated into an index score for each station, each day sampling occurred. Index scores are calculated for the years 1973 through 1997. Maps of the watershed are provided. The trends in water quality of the Des Moines and Raccoon Rivers are analyzed using non-parametric statistics.
