Reservoir releases April 1 to October 31 were 56,080 acre-feet which was 31,100 acre~fcet less than total diversions. Runoff from areas below the reservoir and return flows provided 36 per cent of the water Jivcrtcd during the irrig:Hion season. River flow was passed through the reservoir llvcraging: 38 d.s. from November I, 1963, to Dccember 7,1963 2.8 c.f.s. from December 8,1963, to April 6, 1964 103 d.s. from April 12, 1964, to May 29.1964 96c.f.s. from June 25,1964, to October ]1, 1964. Stlltclinc flow for corresponJing periods averaged 38 c.f.s., 48 c.f.s., 42 c.f,s., and 2Y c.f.s., rcspectivclr. The: total discharge Enr the )'ear at Garden City was 28,240 acre- feet of ",'hich 4,910 acre-feet occurred as winter flows. Runoff from rains in late May and e,lrly June accounted for an acldjtional 21,430 acre-feet or about 76% of the totrtl discharge. The remaining discharge at Garden City was 1.900 .1crL'-fcct O[ :10 ilvcr;lgc of 4.R ('J.s. 8. Gaging StatimlS Stream-flow records of satisfactory a.ccuracy were obtained ;\t the Compact stations. Emph:lsis was continued on performing additional field work to obtain the requlrcd accuracy and on furnishing the stream- flow data to the Administration illld the State oRlciJJs on a current b~lSis. Conditions at the station on the Arbns.1s RivC'r at Ltls Animas remained unfavorable because, of the varying percentages of the flcrv...r in the channel by-passing the gage. The st:ltion will probi1bly h;Jve t() be relocated within the next two years because the Colorado State High- way Department expects to let the contra..:t for the new bridgl: early in 1966. lnvestig.-ttions arc being rn;uJe on the possibility of constructing a stabilizing section in the channel lx.tween the pitrs of the new bridge ancJ of relocating the station upstream from the bridge. The PM radio stage-reporting equipment for the two mflow stations. at Las Animas and the relay stations at John Martin Dam was ordered during the year. It is to be del1vcred in December and will be installeclas soon as possible. The obsolete AM radio equipment at the two State line stations opcr,ltcd s:Jtisfactorily mnst of the year but is not depend~lblc. Recommcndatlons were made to the Adminis.tration that funds be pro- vided in fisc.:Jl year 1966 to replace. this equipment with the slime type that is being installed at the Las Animlls stations. The Administration approved a coopera.tive agreement with the U. S. Geological Survey {or fiscal yoar July 1. 1964, to Junc 30, 1965. for $11,600, $5,800 from each porty. Twelve hundred dollars is for the 1 u/t operation of the Compact gaging station Clt Lamar, $2,400 for rartial support of the other five Compllet gaging stations. and $8,000 tor the procurement of the remainder of the radio equipment for the two inflow stations at Llts.
