Beginning in 2002, stream gauges measure discharge every 10 minutes. Automated samplers collect water samples from most flowing sites on a daily basis, with additional samples collected during high flow events on some stream locations. Since 2004, monitoring equipment measure discharge and collect water samples from multiple fields. Measurements of sediment from some field sites, along with nitrogen, phosphorus, and herbicides concentrations from all sites in these samples assess water quality. Meteorological stations since 2004 measure precipitation, temperature, relative humidity, and solar radiation.
