<br />. <br /> <br />., <br /> <br />The resulting storable flow at Weber Roservoir by months <br /> <br />for the periods of record at Mancos, and by years for the period <br /> <br />when Mancos record is lacking, appears in Table 6. <br /> <br />Storable Flow at Jacks'ln Glllch Reserv0ir <br /> <br />By reference to the tamllation on page 15 showing the <br /> <br />distribution of flow betV'een the several forks of l&'1ncos River, <br /> <br />it appears that the flow of West Mancos River is 65.511. of the <br />flow at Mancos gaging station. The puint of diversion to Jackson <br /> <br />Gulch Reserv')ir is ab',ut six miles upstre8_'ll and the intervening <br /> <br />ar8a is one of lcw runGff comparGble to the area between ~~cos <br /> <br />and Towaoc, so that 64.7~ of the flow nt Mancos ga~e is avail- <br /> <br />able at the pGint of div"rsion. <br /> <br />Storable flGW at this diversion pccint during the years <br /> <br />of record at Mancos W3S C(!n:puted '"IS fc.llows: "fter ~Aay 1, gaging <br /> <br />st'"lti'm flow in excess of 120 seccmd-feet ""'"s c0nsidered storable <br /> <br />until flow at the gGge re"-ches 270 secund-feet. The capacity <br /> <br />of the feeder canal being 150 second-feet, n flow of 270 second- <br /> <br />feet or more provides 150 second-feet of storable ",at.or.
