<br />6, Facts about the John Martin Project:
<br />The John Martin Reservoir Project was built by the Corps of
<br />Engineers, United States Army, The project was authorized by
<br />Congress in the Flood Control Act of June 22, 1936, when the federal
<br />responsibility for flood control throughout the country was assigned to
<br />the Corps of Engineers, It is located on the Arkansas River, 58 miles
<br />upstream from the Colorado'Kansas stateline and 18 miles upstream
<br />from the city of Lamar, Colorado, Constructon of the project began in
<br />the Call of 1939, but work was suspended by World War II from the
<br />spring 01 1943 to the spring 01 1946, The project was completed in
<br />October 1948 at a cost of about $15 million, The War Department Civil
<br />Appropriation Act of June 24, 1940, changed the name 01 the project
<br />from Caddoa Reservoir Project to John Martin Reservoir Project, in
<br />honor of the late Congressman John, A, Martin of Colorado, It is
<br />operated by the United States Army Engineer District, Albuquerque,
<br />New Mexico, Mr, Russell Smith has been the resident superintendent 01
<br />the project since October, 1976,
<br />The John Martin Reservoir Project is part of the comprehensive
<br />plan for the control of floods and the development 01 the water
<br />resources DC the entire Arkansas River basin. The reservoir provides
<br />270,375 acre,Ceet of storage capacity for flood control. It protects the
<br />fertile Arkansas River Valley below the dam, It provides 350,951 acre,
<br />feet of storage space for conservation and recreation. John Martin
<br />Reservoir supplies water to the irrigated lands below the dam as Car as
<br />Garden City, Kansas, The top of the conservation pool is 3,851 Ceet
<br />above mean sea level, which provides 350,951 acre-feet of storage for
<br />irrigation, The reLease of stored. flood waters in excess of the con-
<br />servation and recreation pools and above elevation 3,851 feet is planned
<br />so that, when combined with flows originating downstream from the
<br />dam, the capacity of the channel will not be exceeded, Upon request oC
<br />the Arkansas River Compact Administration, irrigation water Cor
<br />downstream water users is released through the outlet works in the
<br />base 01 the dam, Downstream flood damages prevented by John
<br />Martin dam already exceed the cost 01 the project. Benefits have
<br />already passed the $92 million mark,
<br />Recreation and lavorable fish and wildlife habitats are derived from
<br />this project. With reservoir lands open to all, there are many attractive
<br />public use areas for outdoor recreation. water sports, fishing and
<br />boating, or just relaxed living, During construction some embankment
<br />material was obtained from a 75'acre tract of land immediately
<br />downstream of the dam, This excavated area, averaging 12 leet deep,
<br />filled with water and formed Lake Hasty, the center of year-round
<br />recreation.
<br />John Martin Dam consists of a concrete gravity structure 1,644 feet
<br />long and 120 feet high, and an earthfill structure 2,600 feet long, The
<br />concrete gravity structure contains a gated spillway provided with
<br />sixteen 30 feet by 64 feet tainter gates with their operating machinery,
<br />There are earthen wing dams on either side of the main dam, The
<br />north wing dam is 3,880 feet long, connecting to the earthfill structure
<br />01 the main dam at the north abutment, The south wing dam is 5,807
<br />feet long and connects to the south end of the concrete structure of the
