<br />for that purpose. ~e plan as advanoed by Mr. L. L,. stimson, County <br />Surveyol' for Weld County, was to enlarge the IarwEl-Poudre Canal to <br />a width of 40 feet, with a lower bank 13 feet high, desigllOd to carry <br />water to a depth of 10 l'eet. under this plan each i.nflowing natural <br /> <br />.:stream valley would becone latemporary storage resez'Voir '~o the extent <br /> <br />that the raised ditch bank W1~uld cause water to back up-stream. It was <br />calculated that the oanal so oonstruoted would oal'r;)' 2800 seoond feet <br />of water and that this oapac:lty 'VIOuld be s.uffioient to relieve the <br />flood oonditions in all the 'I;ributary stre.am basins orossed by the <br /> <br />ditch. <br /> <br />Work on this projec;; was conunenoEld at the Mo-Gre1'T ReseI'Voir <br /> <br />and was oontinued for a dist!lnce of 17,000 feet, nearly to Eastman <br /> <br />Creek orossing. However, thE' bottom was not enlarged to the full forty <br />feet wide for the whole of this distance. Approximately 120,000 oubio <br /> <br />yards of exoavation was made at an approxi.mate cos;; of $25,000, of' <br /> <br />whioh $15,350 was for labor a.nd the remainder was for equipment. <br /> <br />This project was aba.ndoned on accbunt of th.3 shortage of funds. <br /> <br />In its present condition, with banks broke):]. and wash'3d out in several <br />places, the Iaramie-Poudre Canal will not oonvey mOl"l9 than 50 to 75 <br />seoond feet of flood waters a;way from the vicinity of the Town of Nunn. <br />With exoavation at a few points along the ditoh bei;mlen Nunn and Lone <br />Tree Creek (to eliminate a fe'\'{ high places), and vri.th widening of the <br /> <br />ditch bottom to approximately 20 feet, the carrying oape.city would be <br /> <br />inoreased to 300 o:r- 400 cubic feet per second of time" assuming the <br /> <br />broken be.nks and breaks at NUlm Draw and Lone Tree Creek be repaired. <br />Adequate spillways might be installed at the, Nunn Draw and <br /> <br />then at points East of Nunn where natural drainage enters the ditch. <br />, <br /> <br />-:1.3- <br />
