u.s, Water Resources Council and the ten states of
the Missouri River basin. The study area included
all of the Missouri River basin's drainage in the
United States. The major objectives of the study
were: (I) to assemble a database describing historic
water availability and uses In the ten-state
Missouri River basin that would be acceptable to
the state and federal agencies involved in water
management; and (2) to develop a computerized
water accounting system incorporating the
database that would aid in estimating the effects of
using future, additional quantities of water in the
basin, By action at its September 28, 1981, organi-
zational meeting. the Missouri Basin States
Association made a commitment to complete that
study following termination of the Missouri River
Basin Commission.

In response to the first study objective, the nearly
50 state and federal agencies that participated
in the study developed an extensive database as
part of the overall water accounting system. That
database was completed during FY82 and
contains information collected during the hydrology
study. The following data and supporting
information are contained in the database for each
of the 93 drainage areas called node basins:

(1) depletors (water users), annually, for the
period 1944 thru 1978;

(2) historic depletions and historic streamflow, in
acre-feet by month, for the period January
1944 thru December 1978;

(3) 1978 level depletions, in acre-feet by month,
for the period January 1944 thru December
1978;

(4) reservoir inflow data, in acre-feet by month,
for the period January 1944 thru December
1978;

(5) narrative information, for each node basin,
including general information, compacts and
court decrees, summary of water rights,
and a summary of state water laws; and

(6) supporting information, including:

a. a list of Water Resources Council hydrol-
ogic accounting units in the Missouri
River basin;
b. a list of Missouri River basIn node basin
names and numbers;
c. a list of U.S. Geological Survey gauging
station numbers;
d. drainage areas for each node basin; and
e. latitude and longitude of each gauging
station.

Information from the database is now available on
computer printouts for use by those having an
interest in water resource management. This is the
first time that a common water use database has
been available for this 523,000 square mile area
which constitutes one-sixth of the contiguous area
of the United States.

During FY82, a QUERY program was developed to
meet the second objective of the study. The
QUERY program of the Water Accounting System
is designed to permit analysis of impacts of future
water use proposals on future streamflow at the
93 locations in the basin. By use of the QUERY
program, cumulative impacts on streamflow result-
ing from water use in or export from the Missouri
River basin can readily be assessed.

Four work group technical reports resulting from
the study were completed during Fiscal Year
1982. They are: (I) Surface Water Supply, Includ-
ing Instream Water Use; (2) Ground Water
Depletion; (3) Agricultural Water Use, Including
Identification of Irrigated Lands; and (4) Municipal,
Industrial, Energy, and Rural Domestic Water
Use. In addition, a draft final report for the entire
study was prepared and transmitted to the U.S,
Water Resources Council.
