that made a proposal was quoted a prise of 10 acre feet of adequately processed sewage for 1 acre :soot of oinking water. The users of Riverside Irrigation District mw . 1 also :'rant and maybe will need some of this water - or their oi.m domestic use. Floods, drouths, river flOWs in the past are common knowledge. The building of facilities to control and spread vrater on land and to the cities has created a new set of conditions, the drilling of wells for irrigation, the ponding of : for re- creation, all if built 10 to 20 years ago can be evaluated. The construction of tra,nsnountain diversions, additional storage reservoirs, :Mood control darns, the grot-rth of urban communities all will have an of feurj': upon the Say ith Pla tte River. The things that occur above Kexsey, Colorado have a direct effect upon the Riverside system. The federal, state government and municipalities have spent millions of dollars to study th'-s aspect. The factors to evaluate are many, the ur.]anoWn s of precipitation, the devious routes that crates travels in the continuous cycle, combined with water rights lawyers have given results that are nebulous at best. The writer of this paper and necessarily using short tuft es- tablishing arbitrary values on each of glee i. elements, believes that (1) catastrophic floods -at :ersey will not occur; (2) the winter flows will be larger due to the municipal and incustrial use; (3) the sum ier and irrigation floe's will not be materially changed. The most promising solution for the 21tiverside system out of many Possibilities, some of rrhi ch are partial solutions for part of the problem, others sALW-3 One deficiency but not another, would be to construct lil.d Cat Reservoir ^ilec'. as Riverside Reservoir No. 2, a plan Which is not nets. The original idea was set forth by evidence of a filing nap by the original Board oZ Directors Of the Riverside Zx 1sa:' 1 .irirx Dis'ri.ct in 1908 and reaffirmed in 1910. in retrospect and due to the location of the present canal, it appears that the original ditch survey contemplated going up Wild Cat Creek on the West side cr_e:oc,,ing the Creep with a dirt dike with a spillway and then returning to the present ditch line on the East side, which alloering for grade to make the water run mould have made the riverside Ditch sortie 8 to 10 miles longer. Economics undoubtedly shoved that he construction of a 3300 foot long siphon was cheaper 'clean the construction of the long ditch. As a result, there is a differential of almost 12 feet in water level from the ease: side or outlet to the Crest side or inlet. They must have been quite serious about the construction at that time because of the quality of the survey that we now find filed in 1908 and as enlarged filing in 1910. The estut►ated cost for the 1908 filing was $175,000.00 and the 1910 filing added $147,862.00 or a total of $322,8G2.00 construction cost. it is doubtful that this would have been enough money even at that time to have adequately faced the dam against erosion. Riverside Reservoir during the summer of 1910 hacl the 4 inch concrete facing fail in places and the system had to - repair and make the No. 1 more safe so there would have been no means to cinance the No. 2 Reservoir or Wild Cat Reservoir at that time. The utility of this reservoir, if constructed then or now, on the sortie plan would. be 20,400 acre feet of storage. It is possible to make a cut through a ridge some 3400 feet in length with a maximum cut of 4 feet to save Sh miles of inlet _4-_
