<br />FRYING PAN-ARKANSAS PROJECT, COLORADO

<br />water (including the 2,000 acre-feet of Wurtz ditch water) and an
<br />ultimate additional need of 15,000 acre-feet by the year 2000. The
<br />city has also expressed interest in obtaining treatment of its present
<br />supply of 21,000 acre-feet.
<br />29. Canon City and Rocky Ford obtain municipal water from the
<br />Arkansas River, Canon City has not requested project water,
<br />30. The towns of Manzanola, Rocky Ford, La Junta, Las Animas,
<br />and Lamar, and the off-stream towns of Crowley, Wiley, and Eads
<br />have requested treated municipal water from the project to replace
<br />entirely their present supplies. Their immediate needs are abou I.
<br />8,000 acre-feet.
<br />31. Flood control,-Few damaging floods of record have occurred in
<br />the diversion area and in the Arkansas Valley down to Canon City.
<br />From there eastward, however, damaging floods increase in freq uency
<br />and volume to the mouth of the Purgatoire River. The largest flood
<br />of record in the project area occurred in June 1921. Intense rains
<br />caused flows at. Pueblo estimated at. 103,000 second-feet., Down-
<br />st.ream tribut.aries contributed to the flood until the peak of 200,000
<br />sec011d-feet was reached at La .Junta, The flood killed at. least 78
<br />persons; property damages exceeded $19,000,000, including $10,000,-
<br />000 in Pueblo.
<br />32, As a result of that disastrous flood, a barrier dam across the
<br />Arkansas River, 6 miles west of Pueblo, and an improved flood way
<br />channel through the city were completed in 1926, Another flood-
<br />control structure, the John IVlartin Reservoir, located on the Arkansas
<br />River near Lamar, Colo., was completed in 1949 by the Corps of
<br />Engineers. A multiple-purpose project, 281,000 acre-feet of its
<br />701,000 acre-foot capacity are allocated to flood control.
<br />33, A flood danger still exists from Pueblo downstream to the John,
<br />Martin Reservoir. The Corps of Engineers has estimated that the
<br />annual damages along that reach of the river average $890,000. The
<br />initial development could eliminate about 66 percent of that probable
<br />damage,
<br />34. Associated needs,-Sediment control, stream pollution abate-
<br />ment, enhancement of the environment for fish and wildlife, and
<br />provision for recreation are other needs of the project area associated
<br />with water development. Industrial expansion, conservation of
<br />forest and range lands, and stabilization of the entire economy by
<br />balanced diversification of interest are recognized as long-range
<br />objectives. The initial development could immediately ameliorate
<br />some of the problems stemming from those needs, Resolution of the
<br />'long-range objectives will require coordinated and unselfish coopera-
<br />tion by all citizens, agencies, and entities concerned.
<br />35, Mention has already been made of the acute sedimentation
<br />problem affecting irrigation in the main Arkansas Valley, At Pueblo
<br />the river annually transports about 944 acre-feet of sediment, Ap-
<br />proximately 42 percent, of that sediment is deposited 'in reservoirs,
<br />cnnals, und laterals; about 38 percent becomes undesired deposition
<br />on the irrigated lands, Aggradation of the river channel has made
<br />some irrigation diversion structures inoperative; other diversion
<br />structures have necessarily been raised. Removed sediment now
<br />lines some canal banks and further disposal has become very ex-
<br />pen~ive. Canal sand traps have become inoperative. The only
<br />apparent immediate solution is provision of reservoir space specifically
<br />for the deposition of sediment.
