<br /> <br />-14 - <br /> <br />- 13 - <br /> <br /> <br />reducing peak flows due to snowmelt is marginal due to the <br />broad rather than sharp peak runoff hydrograph which 1s <br />characteristic of a short duration, high intensity summer <br />thunderstorm. For example, had the dam been in place during <br />the storm of June lS65, as shown on the hydrograph on Plate <br />1, the peak flow would only have been reduced to 1180 cfs <br />from 1250 cfs and flooding would still have occurred. <br /> <br />OTHER FLOOD DAMAGE REDUCTION MEASURES <br /> <br />Reservoirs, lakes and ponds in the Blue River Basin <br />above the town of Breckenridge provide only incidental flood <br />protection. This storage and trans-mountain diversions near <br />Hoosier Pass has served to reduce peak flows in the study <br />area. <br /> <br />Breckenridge is eligible for flood insurance as provi- <br />ded by the National Flood Insurance Program. The town has <br />been advised by the Federal Insurance Administration that <br />special flood ha~ard areas exist. The program requires the <br />town to adopt and enforce land use control measures that <br />will guide future development of land in the flood-prone <br />areas to avoid or reduce flood damage. <br /> <br />FIGUPE 2 . Goose <br />Pastut'c Ta1'>1 <br />spi/.l'JilY <br /> <br />Although the town has had a flOod plain ordinance since <br />lS71, it has not been adequate or effective in controlling <br />development in the flood plain. A new ordinance is under <br />preparation which more closely follows published state <br />guidelines. <br /> <br /> <br />C\) <br /> <br />ier:,"rd 'Jce Con,,~:;"~ ~',tl1 E,:irn!c's, h1c <br /> <br />--- --~- -------------- <br /> <br />F'Ia'.HiE 1.
