Summary:  View help for Summary Automated Sigma pump samplers were used at all RCEW gauging stations to collect instantaneous point measures of suspended-sediment concentration. The US Department of Agriculture, Agricultural Research Service, Northwest Watershed Research Center initiated a stream discharge and suspended-sediment research program at Reynolds Creek Experimental Watershed in the early 1960s. Samples of suspended-sediment concentration were collected at Outlet, Tollgate, and Reynolds Mountain East gauging stations starting in the 1960s and continuing to the present. In early years, samples were collected manually during storm events using integrated samplers at the large weirs or simple grab samples at the smaller weirs. Later, a variety of early sediment samplers such as the U.S. PS-67 and U.S. PS-69 pumping samplers were tested and used in RCEW through cooperative efforts with other Agricultural Research Service locations, federal and state agencies, and universities. In recent years, automated Sigma pump samplers have been used at all gauging stations to collect a continuous record of instantaneous point measures of suspended-sediment concentration during high and low flows. Drop-box weirs have also performed well in RCEW over a wide range of discharges and sediment loads. Four additional types of stream-gauging devices are used in RCEW: (1) self-cleaning overflow V-notch (SCOV) weir, (2) 30 V-notch weir, (3) 90 V-notch weir, and (4) Parshall flume. All stations are equipped with stilling wells and floats for obtaining instantaneous measures of stage height. Instrument shelters are heated to permit collection of discharge and sediment data during cold winter periods. Gauging stations are visited on a weekly or biweekly basis to obtain independent stage height readings for error checking and to service all instrumentation. Stage height measurements were originally recorded using Leopold-Stevens A-35 and FW-1 strip chart recorders, later supplanted by electronic data loggers.
