Nutrient and Sediment Loss from the Watersheds of Orleans County Year 2: Johnson, Oak Orchard and Sandy Creek Watersheds. June 1998 - May 1999In recognition of the need to acquire a uniform, organized approach to addressing surface water degradation and given the diverse nature of non-point sources of pollution, the Soil and Water Conservation District has recently formed a committee whose specific task is to address water quality issues. Since the reduction of non-point source pollution is likely to occur through the implementation of Best Management Practices (BMP's) and changes in land use regulations, this committee provides the necessary foundation for these changes to occur. This committee has become known as the Orleans County Water Quality Coordinating Committee (WQCC). With the combined expertise of the Water Quality Coordinating Committee and the availability of actual field data, progress towards healthier freshwater resources is underway. A recommendation of the WQCC was to move forward in prioritizing the major tributaries in terms of high nutrient losses from the watershed. The objectives of Orleans County's program include: 1. Determination of the status of Orleans County's primary surface waters and observe changes over time; 2. Documentation of what types and amounts of nutrients may be adversely impacting water quality and the conditions which generate them; 3. Determination of what urban, rural, industrial and agricultural practices within a watershed may be impacting water quality; 4. Development of a technical database for informed water quality management decisions; and, 5. Assessment of the feasibility and effectiveness of potential control measures likely to be used to reduce non-point and point sources of pollution. Determination of sources and magnitude of soil and nutrient losses from a watershed is prerequisite to remedial action and essential to making cost-effective land management decisions as it reduces the likelihood of costly miscalculations based on the assumption of soil and nutrient sources and modeling rather than their actual identification. We have found that this process enhances the ability of concerned groups to obtain external funding for demonstration and remedial projects.
Segment Analysis of Johnson Creek: The Location of Sources of PollutionJohnson Creek is located in the southern portion of the Lake Ontario watershed, Orleans and Niagara Counties, New York. The relatively large watershed encompasses 98.6 square miles and flows into Lake Ontario near Kuckville, New York. Two years of continuous water quality monitoring indicated that the Johnson Creek watershed was a source of phosphorus, nitrate, organic nitrogen, sodium and soils to Lake Ontario. That is, Johnson Creek and the watershed it drained are a source of nutrients and soil pollution to Lake Ontario relative to other watersheds of similar size in western New York. Where are the sources of nutrients, soils and salts within the Johnson Creek watershed? To answer this question the Soil and Water Conservation Districts of Niagara and Orleans Counties, along with the Center of Applied Aquatic Science and Aquaculture at SUNY Brockport, undertook the process of identifying the point and non-point sources of nutrients and soils by stressed stream analysis or segment analysis. With this report, we provide evidence suggesting the location and the intensity of pollution sources in the Johnson Creek watershed. We have identified three areas/sources in the Johnson Creek watershed that have consistently had high levels of nutrients, soils or sodium. What follows is a synopsis of what pollutants are being lost and where the sources are located. Maps are included in the narrative to locate these sites.
