<br />Parkinson, a 7,year old boy, drowned. The family livled near the Eaton Ditch, which overflowed <br />above their house after they had gone to bed. <br /> <br />Flooding did occur in 1924 with flows several feet deep in the vicinity of Jax Surplus. It is <br />unclear as to whether this was actually due to overflows from the Poudre River. <br /> <br />Presently, the impact of new development in the lower basin of Dry Creek is already increasing <br />the magnitude and frequency of drainage flows. In the past, much of the excess drainage was <br />intercepted by irrigation canals. Today, these canals no longer have the capacity to intercept <br />larger flood flows and increased drainage flows. The irrigation canals should be bypassed with <br />proper conveyance provided in the drainageway. <br /> <br />Fossil Creek <br /> <br />Fossil Creek is a right bank tributary of the Cache La Poudre River. It flows from ea~t to west <br />through Fort Collins into Fossil Creek Reservoir. The drainage area of Fossil Creek is <br />approximately 21 square miles above Fossil Cre.ek Re:se:rvoir. The Fossil Creek channel is <br />generally incised aIld characterized by bed and bank instability and meander migration ,md <br />channel cutoffs. Fossil Creek charmel characteri,tics ,md stability studies are discussed in the <br />"Channel Stability Studies" section below. <br /> <br />The Fossil Creek basin is relatively undeveloped and floods in the past have gone unnoticed <br />except for some of the access roads to subdivisions which create ponding and road overtopping. <br />There is no gaging station in the basin. Local newspaper and resident accounts describe flood <br />events occurring in 1902, 1938, 1965, 1977, and 1979, however, very little detail on flooding in <br />Fossil Creek is available. <br /> <br />A newspaper account of the September 24, 1902 flood stated that,"between 4:20 p.m. Saturday <br />night and 5 :20 p.m. Sunday night, Fossil Creek Reservoir gage reading indicated a fourteen foot <br />rise which amounts to 44,000,000 cubic feet of water in about 24 hours (an average of over <br />12,000 cubic feet per second). During Sunday night Fossil Creek continued to add to this body of <br />water at the rate of 500 cubic feet per second anel Monday morning found the reservoir nineteen <br />feet deep." <br /> <br />Boxelder Creek and Cooper Slough <br /> <br />Boxelder Creek is a left bank tributary of the Cache La Poudre Rjver. It flows from north to <br />south, beginning at its headwaters in southern Wyoming at an elevation of 7720 feet, m.s.l. and <br />ending at its confluence with the Cache La Poudre River at an elevation of 4860 feet, m.s.l. The <br />Boxelder Creek drainage basin covers an area of251 square miles in Wyoming aIld Colorado. <br />The basin is about 32 miles long and 8 miles wiele. Boxelder Creek flows along the northea~t <br />edge of Fort Collins and joins the Cache La Poudre River south of Drake Road. <br /> <br />13 <br />
