CHEMICAL QUALITY OF PRECIPITATION
JAMES RIVER BASIN
470732099140204 WOODWORTH, ND
(National Trends Network precipitation-quality station)
LOCATION.--Lat 4714'32", long 9914'02", in SE1/4SW1/4SW1/4 sec.12, T.142 N., R.68 W., Stutsman County, Hydrologic Unit 10160002,
at U.S. Fish and Wildlife Service Northern Prairie Wildlife Research Center, at Woodworth Experiment Station 2.8 mi east and
1 mi south of Woodworth.
PERIOD OF RECORD.--November 1983 to current year (weekly composite).
INSTRUMENTATION.--The composite sample collector is an Aerochem Metrics1 model 301 wet/dry precipitation collector mounted on
ground surface. Precipitation quantity is determined by a Belfort1 model 5-780 recording rain gage equipped with an event
recorder and an Alter-type wind screen. The recording rain gage is installed 17 ft east of the sample collector with gage mouth
and collector bucket elevations of 50.75 in above land surface.
REMARKS.--The station is located 300 ft west of an event sample-collection station which was operated by the North Dakota State
Health Department (station discontinued 1987). Continuously recording meteorological instrumentation for air temperature, wind
speed, and wind direction were installed 9.8 ft above land surface at the event station. Data presented are provisional analyses
by the Central Analytical Laboratory of the Illinois State Water Survey and have not completed quality-assurance review by the
National Atmospheric Deposition Program. Analyses are determined from water taken from the sample collector.
