Our stream monitoring program is a long-term data collection program that allows us to understand local as well as regional changes in the environment feeding our stream. The program began in 1985 and is the longest continuous chemistry dataset about the quality of streamwater in our region. Our program includes monthly grab samples collected at two sites on the East Branch of Wappinger Creek on the Cary Institute property. Stream samples are collected at the end of every month at low flow and are analyzed in our analytical lab for a suite of constituents that are important to ecosystem function. Additionally, we collect continuous temperature, stage height and specific conductance data at 15-minute intervals at one of the two sites.
