Nutrients and Suspended Solid Losses from Oneida Lake Tributaries, 2002-2003: Butternut, Big Bay, Chittenango, Canaseraga, Cowaselon, Fish, Limestone, Oneida, Scriba and Wood CreeksIn summary, the goal of this report is to provide: ? An interpretive summary of chemistry trends for each subwatershed sampled in the Oneida Lake watershed; ? A prioritization of the tributaries, based on nutrient and soil loss; and ? A comparison between nutrient and soil loss from Oneida Lake subwatersheds to other central New York watersheds with different land use practices.
Small Intermittent Rivulets versus Major Tributaries: The Loss of Soil and Nutrients from Selected Small Subwatersheds Compared to the Major Subwatersheds of Canandaigua LakeThe rivulets that drain small subwatersheds of Canandaigua Lake contributed significant amounts of total Kjeldahl nitrogen, nitrate, soil and phosphorus to Canandaigua Lake. The large amount of material being lost from these small subwatersheds was surprising when compared to larger nearby watersheds despite the fact that only two events were sampled. This pilot study shows the potential importance that small intermittent streams may have on the health of Canandaigua Lake. We recommend that the watersheds studied be further interrogated as to potential land-use practices that could be the cause for the high losses observed. A further, more intensive study, looking at a larger number of rivulets for an annual cycle is warranted. A study of this nature will more accurately determine the full impact these numerous subwatersheds are having on the “ecologic health” of Canandaigua Lake.
The Muckland Demonstration Project : Agricultural Non-point Source Pollution ControlThe many muck fields in agriculture that exist in Oswego County offer an opportunity to demonstrate the feasibility of using artificially constructed wetlands to reduce nutrient levels in water draining from these highly fertilized, productive agricultural systems. An artificial wetland was constructed adjacent to a large muckland farm raising onions and sorghum. Water draining from the muck fields was pumped into the constructed wetland and allowed to flow naturally out of the wetland after a retention period determined by the flow regime. The question being asked was can nutrients and sediments be effectively removed from muckland drainage water by an artificial wetland?
