We are collecting data and assembling background physical overlays for a variety of variables and parameters. Key coverages include topography (digital elevation model), soils information, land cover and land use, geology, cadastral information, and census data. This is all information that we can assemble from existing databases. We use the new Vermont Geomorphic Assessment methodologies to evaluate the current condition of the stream reaches. Samples are taken with an autosampler at each of the three flow monitoring sites. The autosampler is programmed to begin sampling when flow increases above a minimum threshold and to continue sampling every hour until the flow falls below that threshold or the sampler exhausts the sample bottles (24 h). Samples are analyzed for pH and conductivity by meters and for total nitrogen (TN), total phosphorus (TP), nitrate (NO3), ammonium (NH3), soluble reactive phosphate (SRP), chloride (Cl), total suspended solids (TSS), and indicator microorganisms (E. coli) by standard methods. If soil samples indicate the presence of herbicides or pesticides, storm water samples are analyzed for these contaminants as well.
We are developing a variety of simulation models to analyze the dynamics of flow and the retention capacity of the watershed. These are developed and applied in a participatory fashion with stakeholders involvement. The models are useful to identify restoration priorities and to compare various interventions to optimize for cost and socio-economic impact.
