The Reynolds Creek Experimental Watershed streamflow and sedimentation program provides fundamental information for research into hydrologic processes, precipitation-runoff relationships, hydrograph characteristics, water yield, and the interactive effects of climate, vegetation, soils and land use on rangeland hydrologic response. The RCEW basic data set provides a basis for evaluating temporal variability in hydrologic regime and water yield, and for evaluating spatial variability within a typical upland rangeland landscape. Rangeland watersheds, with high-elevation seasonal snowpack that provides a major source of streamflow for spring and early summer, supply water for on-site biological production, in-stream and near-stream habitat, and downstream uses including irrigation, recreation and hydropower generation. Streamflow and sediment data from RCEW are particularly valuable for understanding complex upland runoff and sediment generation processes of rain and snowmelt on snow and frozen soils which can produce flooding and property damage throughout the Northwestern United States.

This graph reflects the raw data that has been collected and may sometimes go wildly off-scale. Real data does that sometimes. To zoom in the time scale hold the left mouse button down and drag across the region of interest. To select a smaller y-data range hold the left mouse button down inside the graphed data area and drag to the scale of interest. To pan through time hold the shift key down and the drag the mouse left or right while holding the left button down. Double click to return to full time scale. It's not as hard to do as it sounds but it may take some practice.
