GJJ2J5 ,34 at least three standard stations along a river for recording dally evapora- tion, precipitation, temperature and wind velocities, the installation of automatic gage height recorders On all intervening ditches and on all tribu- tary streams and visible sources of inflow, and finally additional hydro- graphers for making the large number of stream measurements under varyIng conditions and stages of flow, together with an adequate force to police all headgates. Up to the present, my Department has not had the funds to finance such a study and to put such a program Into effect." In 1939 and 1940 Mr. G.F. lacey, the Divisional Engineer on the Arkansas river prepared a comp.rehensive Hudy of the administrative problems and pro- cedures concerning reservoir runs from Twin lakes to the Colorado Canal. In his summary conclusions and observa~ions, he states "Numerous attempts have been made to determine the exact amount of loss in transit between Twin lakes and the various main river gaging stations, as the reservoir head passes down the rive r. " '~hese studies and investigatlons have been helpful, and information has been obtained, which has proven of great value in establishing certain admin- istrative practices and procedures. In my opinion, exact determinations as to loss In transit to the reservoir head In progresslon are Impossible be- cause of the many influencing factors encountered which are beyond control. There are too many variables present in the situation, which tend to obscure the graphic record and maKe objective conclusions difficult." lacey suggested a l~!o charge for transit loss of reservoir water that was run from Twin lakes to the Colorado Canal. On pages 35, 36 and 37 of this report is presented a summary of the Sunnyside Park Ditch case which should be of Interest to all water engineers dealing with the Arkansas River.
