USFS Hydrologic Technician Greg Downing, and visiting researcher Nicolas Vergara, prepare a water chemistry sample from Watershed 02

Greg Downing, USFS Hydrologic Technician, prepares to take a water chemistry sample in Watershed 02

Greg Downing, USFS Hydrologic Technician, maintains the water sampler battery power for the gage house in Watershed 2. The water sampler and data logger batteries are charged by a solar panel.

The weir in Watershed 02. The flume is used to measure the volume of water leaving the watershed. The flume, and streamflow record, started in 1952. Stream chemistry measurements began in 1981.
