CHEMICAL QUALITY OF PRECIPITATION
RED RIVER OF THE NORTH BASIN
484714097442301 ICELANDIC STATE PARK, ND
(National Trends Network precipitation-quality station)
LOCATION.--Lat 4847'14", long 9744'23", in SW1/4NW1/4SW1/4 sec. 10, T.161 N., R.55 W., Pembina County, Hydrologic Unit 09020313,
at Icelandic State Park 5.6 mi west of Cavalier.
PERIOD OF RECORD.--October 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 20 ft east of the sample collector with gage mouth
and collector bucket elevations of 50.75 in above land surface.
REMARKS.--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.
