In 1977 a sampling program was started for the Kashong watershed in conjunction with the ongoing sampling program for Fall Creek. It drains an area along the Ontario-Yates county boundary and empties into Seneca Lake. In contrast to Fall Creek, the land is more intensively farmed with much less dairy farming and more vegetable farming. About 20 samples were taken from Nov 1977 thru Mar 1979 from several sampling locations. Grab samples were taken during high and low flow events and probably included a fair sample of both high low flow events. Sampling locations and GPS locations are given in the attached location table. There was/is no current flow data for the watershed or its tributaries. However there is flow data for Flint Creek which is adjacent. It is USGS location no 04235250, daily discharge 1959-10-01 continuing through at least 2007-04-29. The flow data from Flint Creek was combined with the chemical analysis from Kashong. Regression of MRP (molybdate reactive phosphorus on centrifuged samples which is an estimate of inorganic P) on flow from Flint Creek was calculated. Next we estimated the frequency of occurrence of ranges of flow for the period 1959-2004 for the Flint and estimated how many days of a given flow range occurred during an average year. From this and the regression an estimated annual loading of MRP was calculated. The net result is 0.25 kg MRP per ha per year. Corresponding loading for fall Creek was 0.13 kg/ha/yr. Annual flow for Flint Creek is about 60 % of the annual flow for Fall Creek so the larger MRP loading means that the flow weighted MRP concentration was about twice that from Fall Creek. The total dissolved P (TDP) loading was also about twice that from Fall Creek; the ratio of MRP/TDP was much higher than in Fall Creek perhaps as a consequence of more manure in Fall Creek and hence more dissolved organic P.
