PROJECT TITLE:

National Trends Network for Monitor-
ing Atmospheric Deposition

PROJECT NUMBER:

CO-83-005

STUDY LOCATION:

Bent County, Colorado

COOPERATING AGENCY:

None--U.S. Geological Survey funds only

PROJECT CHIEF AND
OFFICE:

Ronnie D. Steger, Subdistrict Office, Pueblo

PROJECT DURATION:

October 1983 to September 1986

PROBLEM: Great variability exists nationwide in precipitation quality and
quantity and their potential environmental impacts.

OBJECTIVES: Develop a nationwide information base of precipitation quantity
and quality data. Evaluate regional variations in precipitation quantity
and quality related to regional land use, as well as the way in which
these precipitation quantity and quality variations influence stream
discharge and chemistry.

APPROACH: Operate one precipitation station at the Las Animas fish hatchery
near Las Animas, Colorado, as part of the National Atmospheric Deposition
Network. Obtain information on precipitation quantity, quality, pH, and
specific conductance for storm events. Collect samples for chemical
analyses and send to the Illinois State Water Survey Laboratory.
Coordinate computations of chemical loading and evaluation of areal and
temporal variations in precipitation quantity and quality.

PROGRESS:

Precipitation site was visited each week throughout the year.

PLANS FOR FY 1987: Weekly visitation of the site will be continued.
