Good information was available on the <br /> <br />response time of the ditches at Dry Creek, which would be the <br /> <br />time required for the ditch to become noncontributing. This <br /> <br />concept will receive further analysis later in the "];laster <br /> <br />Drainageway Planning Study". However, a flood warnlng system <br /> <br />utilizing these ditches could significantly reduce the potential <br />for flooding at Fort Collins, if the integrity of the system <br /> <br />could be insured. Without a warning system, however, timely and <br /> <br />proper shutdown of these canals should not be relied upon to <br /> <br />reduce potential flooding downstream. Canal shutdown was not <br /> <br />considered in this analysis. <br /> <br />Field Inspection <br /> <br />I <br />, <br /> <br />!I <br />I <br />t <br /> <br />il <br />II <br />II <br />! <br />'I <br />I <br />III <br /> <br />A field inspection of the basin was made on May IS, 1979. <br /> <br />This inspection showed that all major canals crossing the basin-- <br /> <br />the Larimer and Weld Canal, the Terry Inlet, the Larimer County <br /> <br />Canal, the Poudre Valley Canal and the North Poudre Ditch-- <br /> <br />directly intercept flows from Dry Creek. <br /> <br />Douglas Reservoir was also visited during this trip.
