The Cimarron Basin covers nearly 6,800 square
miles of the southwest corner of Kansas. The basin includes all
or parts of 14 counties. There were an estimated 54,300
residents in this basin in the year 2000, and the population is
projected to grow to 68,500 by the year 2040. The Cimarron
National Grassland is located within the basin and covers an
area of about 100,000 acres. The major river in the basin is
the Cimarron. There are no major reservoirs in the basin.
Principal tributaries of the Cimarron River in Kansas are the
North Fork Cimarron, Crooked Creek, Bluff Creek and on occasions
of high runoff, Bear Creek.
In April 2001, the U.S. Fish and Wildlife Service
listed the Cimarron River in Clark, Comanche, Meade and Seward
counties, from U.S. Highway 54 bridge downstream to the
Kansas-Oklahoma border, as critical habitat for the Arkansas
River Shiner.
The climate of the basin is characterized by
moderate to low precipitation, relatively high wind velocities,
fairly rapid rates of evaporation, a wide range of temperatures
and abrupt, sometimes violent changes in weather.
The economy of the basin is very dependent on
agriculture. Crops grown include wheat, corn, grain sorghum,
soybeans, forage sorghum and alfalfa. Livestock production is an
important component. Beef cattle are the predominant livestock
produced in the basin. Large cattle feeding operations are
common. Beef processing is also a major economic factor in the
basin.
Gas and oil production is widespread and very
important to the basin’s economy. The first gas wells were
drilled in the Hugoton field in the early 1920’s, which remains
a major national gas producing area. Other minerals are of
minor importance to the basin.
Virtually 100% of the water use in the basin is
from ground water. Irrigation is widespread and extremely
important to the area economy. Ninety-seven percent of the
water used in the basin is for irrigation. Just under 90
percent of the basin is cropland of which about 20 percent is
irrigated. Groundwater Management District No. 3 is the major
water management entity in the basin.
