"i't THE AMITY MUTUAL IRRIGATION COMPANY (' I ,1 'I 1538 President's Report TO THE AMITY MUTUI\L IRRIGATION COMPANY TO THE DIRECTORS AND STOCKHOLDERS: . Spring season started with very Uttle winter moisture and poor crop prospects. Since August 1962 the Arkansas river had been at an all time low. Planting in 1965 was delayed by the lack oC winter moisture so when the June dOMl pour and Oood re....ersed this condition there was some reason for rejoicing even though flooding did enormous damage to lands and property in the Valley, 'I . The intensity and amount of the rainfall in the June 18th storm was hard to conceive and spemed to be centered in the area both above and below John Martin dam. Some of the peak flows on the Arkansas river and tributaries as determined by the Anny Engineers and other federal officials are recorded here for future reference. The river at Las Animas peaked at 22,000 c.f.s. The Purgatoire at 631000 c.f.s. Rule Creek south of John Martin Reservoir at 276,000 c.f.s. Mud Creek has been put at 53,400 c.r.s. and the river at Lamar waS measured at 72,800 c.r.s. Caddoa Creek at 26,900 c.f.s. Clay Creek peaked at 153.000 c.r.s. and Willow Creek that flooded Lamar at 24.000 c.f.s. Bulle Creek that flooded !lolly peaked at 187,000 c,f.s, At one time there was 158,000 c.l.s. in the river at Coolidge, Kansas. Only 3800 a.c. or water was stored in John Martin Reservoir during the winter period and when released at 1000 c.C.s. onl3o' lasted 2 da)'s. Such small storage is very unsatisfactory because much of this is taken up by loss in transit and is not available Cor i.rrigation. Winter storage of Arkansas river water is provided for in the Arkansas Rlver Compact. When all the water is shut off at John Martin the effect is most pronounced on the ditches closest to the dam. Very little water is available for the ditches above Lamar when storage is on in John Martin. Article V, A. or the Compact provides (or releases up to 100 c.f.s. of river water but if upstream ditches are permitted to divert the river without regard to this priority there is ver.y little water available for use below or for storage In the Reservoir. This year the river at Las Animas to J\'ovember 1st produced 330,300 aJ. The gauge at Purgatoire station .....as washed out so this amount WQuld be estimated at 254,600 a.f. Rule Creek which has no gauge had an enormous peak during the flood. Out flow from John Martin Reservoir 'Was 287,000 a.c. 256,000 a.i. passed the Amitj" head gate and there was 749,000 a.f. at the State Line. Ditches in District #67 diverted 138,667 aJ., 81,345 aJ. of which wern to the Amil.l'. Use Page 3
