Approximate boundaries of flood-prone- areas are shown on this map. There is, on the average, about 1 chance in 100 that the de-signated areas will be inundated in any year. This information is important to public agencies and pri\'ate citizens concerned with future land developments. The fh:xl.prone areas have bet>n deline-ated through use of readily available information on past floods rather than from detailed field surveys and inspection~, In general, the delineated an'as are for natural conditions and do not take into consideration the possible effects of existing or proposed flood control structures except where those effects could be evaluated. Flood areas have wen idt>n- tified for: (1) urban areas where the upstream drainage basin exceeds 25 square miles, (~) rural areas in humid regions where the upstream drainage basin exceeds 100 !';Quare miles, (:ll rural art:'as in semiarid regions where the upstream drainage basin exceeds 2.')0 square miles, and (4) smaller draina}{e basins. depending on topography and potential use of the flood plains. The 89th C'onKress. in House Document 465, recommended the preparation of floo<l.pront' art'a maps to assist in minimizing flood losses by quickly identifying the areas of vott'ntial flood hazards, More detailed flood information may be reQuirt>d for other purposes such as ~tructural designs, t'co- nomic studies, or formulation of lanrJ.use regulations. Such detailed information may be obtaint><l from the u.s. Geological Survey, other Ft'deral agencies, or State. local, and pdvate aJ{encies. 1979 QUADRANGLE LOCATION I "1tLf -- , ~.~ -J- ~ ) \ ;. \ --, 28\ ,}",? \ o I \J 16 ') \.. < ~- CONTOUR INTERVAL 40 FEET DOTTE.D LINES RFPRESEN1 20.FOOT CONTOURS DATUM 1$ MEAN SEA L[V[l EJ PREPARED BY THE U.S, GEOLOGICAL SURVEY -~ -- \ 7J< (~/"k , I ~ 7271 HOOKER MOUNTAIN QUADRANGLE COLORADO-ROUTT CO. 7.5 MINUTE SERIES (TOPOGRAPHIC) , ~~o\\f-~ b"' ." 0 ,q\V SW/4 PILOT KNOB 15' aUADRANGLE '10 107'07'30" 40.37'30" ~ 4499 I CO ~,.. 1/ I ~ ." ......0 ~ <-" C\j ;/I. 4498 Co ~ 470000 FEET ".,., 34 ~ "", ~ I T.7 N.
