Welcome to the Reynolds Creek Experimental Watershed and Critical Zone Observatory, where federal land management, academia, and private land owners come together to understand carbon dynamics in the West.

Reynolds Creek Experimental Watershed

Reynolds Creek Experimental Watershed was established in 1960 by the USDA ARS to support research addressing water supply, seasonal snow, soil freezing, water quality, and hydrology in semi-arid rangelands of the interior Pacific Northwest.

Weirs on the Watershed

The network of weirs on Reynolds Creek tell the story of the water in the west –its lean years, its banner years, its flood year, and rain on snow years. The weirs span a wide range of streamflow over 50 plus years and integrate the water from the upper portion of the catchment.

Instrumentation and Real-time Data Collection

We are focusing on intensive measurements of soil carbon and above-ground and below-ground processes. Eddy-covariance towers, soil moisture and temperature probes, automated soil respiration measurements, soil carbon dioxide and oxygen measurements, and sap flux data collection occurs at strategic locations throughout the watershed.
