Description
Four tributaries of the upper Taunton River were monitored for four summers from 1999 to 2004 to evaluate the contributions of nitrate nitrogen, soluble reactive phosphorus, and total phosphorus to the upper Taunton River. Automated samplers collected hourly over a 22-hour period. Hydrolab Minisonde data loggers monitored changes in pH, temperature and dissolved oxygen. The data clearly indicate that the Matfield River represents 65 -- 81% of the nitrate nitrogen loading from the tributaries to the upper Taunton River. The summer 2004 nitrate nitrogen load carried by the Matfield averaged 495.8 kg/day while the upper Taunton mainstem averaged 902 kg/day. Summer 2004 data collaboration with the Massachusetts Riverways RIFLS program detected a shift in the soluble reactive phosphorus (SRP) fraction of total phosphorus from 15 -- 65% down to 15 -- 25% during high flows, especially following Hurricane Charles, indicating more of the loading is due to organic sources during storm events.
