The Genesee River Project, conducted from August 2010 to August 2013, provides a detailed picture of sediment and phosphorus concentrations (e.g., weekly water chemistry sampling), nutrient loading, allocation and identification of phosphorus sources, and the effectiveness of management practices on the four major Genesee River tributaries (Canaseraga, Honeoye, Black, and Oatka Creeks), the Upper Genesee River, and the lower Genesee River. With 60% of the P load (412,505 kg P/yr) from the Genesee River to Lake Ontario being of anthropogenic origin, a managed reduction in P lost from the Genesee watershed is apparent. Models using the Soil and Water Assessment …

The Development Of An Stream Water Quality Assessment Index To Evaluate Stream Health Conesus Lake Tributaries Spring 2011, Joseph Makarewicz, Theodore Lewis, Blake Snyder

Joseph C Makarewicz

The major goal was to develop an assessment tool for watershed health utilizing the USDA data base. Such a tool would allow the county to evaluate the status of watersheds; that is, are they improving, getting worse, or not changing. An evaluation tool of this type would allow further development and direction of the Conesus Lake Watershed Management Plan.

Monitoring of two of the USDA streams (Cottonwood Gully and North McMillan Creek) was changed to the spring rather than the summer. This was done as a result of last year’s work which suggested that spring monitoring may provide a better …

Conesus Lake 2008: Baseline Data On The Stream Bank Restoration Project, Update On Water Quality Of Usda Monitored Watersheds, Joseph C. Makarewicz, Theodore W. Lewis, Christiann Severson

Conesus Lake is fed by 18 tributaries and a number of smaller streams and rivulets (Forest et al. 1978). The terrain in the watershed is characterized by gentle slopes at the northern outlet and southern inlet areas. Steep hilly slopes characterize the flanks and southern portion of the watershed. For example, from the middle third of the lake to the southern end of the watershed, the lake and valley are flanked by steep slopes exceeding 45 percent. The soils of the Conesus Lake watershed are mostly derived from locally-occurring shale and sandstone bedrock material that has been reworked by glacial …

After several years of a general decrease in “concentrations” of various nutrients from managed watersheds, substantial increases in the concentrations of nutrients and soil particles were observed in streams during the summer of 2009 (Makarewicz and Lewis 2009). At Graywood Gully, for example, concentrations of soil (TSS), total phosphorus (TP), soluble reactive phosphorus (SRP), total Kjeldahl nitrogen (TKN), and nitrate increased in the stream water. At Cottonwood Gully, after a 5-year decrease, nitrate concentration (NO3+NO2) increased to levels not observed since 2003. Similar increases were observed in the Southwest, Sand Point, North Gully, Sutton Point and Long Point subwatersheds. Several …

Nutrient Concentration And Loading, Identification Of Point And Nonpoint Sources Of Pollution, Total Maximum Daily Load, And An Assessment Of Management Practices Using The Soil Water Assessment Tool (Swat) Model. A Report To The Usda., Mellissa Jayne Winslow, Joseph C. Makarewicz, Theodore W. Lewis

Nearshore Lake Ontario suffers from several beneficial use impairments due to water quality issues from the Genesee River and its contributing tributaries. Segments of Black Creek located in the Lower Genesee River basin are listed as impacted on the New York State 303(d) list because of excess sediment, nutrient, and bacteria losses. Sources of these pollutants from the Black Creek watershed include improperly managed cropland and pastures, dairy manure application, and effluent discharges from wastewater treatment plants. An assessment of the Black Creek watershed was undertaken to determine the nutrient and sediment contribution of Black Creek to the Genesee River …
