Fecal Microbe Distribution And Abundance Used As A Possible Proxy For Nutrient Source Identification In Eutrophic Wilgreen Lake, Madison County, Kentucky, Theresa A. Aguiar, Walter S. Borowski

Wilgreen Lake is a eutrophic lake that has been listed on the EPA’s 303d list as nutrient impaired. Potential sources of this impairment are from humans, cattle manure and fertilizers. We suspect that the majority of nutrients originate from human sources. As a possible proxy for nutrient input, we test our hypothesis by examining fecal microbe distribution and abundance in the lake.
We took water samples at 19 sampling locations on 4 occasions. Sampling spanned 26 June to 15 August with the last 3 sampling events occurring at roughly two-week intervals. These samples were then processed using IDEXX methods, which …

Wilgreen Lake (Madison County, Kentucky) is a eutrophic lake formed by damming Taylor Fork, part of the Silver Creek watershed. The lake is listed “nutrient impaired” by the Commonwealth and the EPA, and it is likely that nutrient input from human activities is affecting water quality. Our study aims first to characterize the physical characteristics and water quality of the lake (2006), and then to determine the specific proportion of nutrient inputs (2007) to the lake with the ultimate aim of improving its water quality.
Research started in May 2006 with work occurring throughout the 2006 field season with the …

Wilgreen Lake is a small (~14 mi2) eutrophic lake formed by damming several tributary streams to Silver Creek, Madison County, Kentucky. The lake receives runoff from industrial and urban areas (Richmond) that comprise ~10% of the total watershed area; most runoff is from cattle pasture or human developments encircling the lake. Present and past developments are on septic systems, and effluent from these systems is known qualitatively to seep into lake waters.
Our research group is currently conducting a study of the lake in order to identify major nutrient sources, and one possible tracer method is to quantitatively …
