<br />several watersheds, This storm affected Little Dry Creek, Big Dry Creek, Plum Creek, and
<br />Cherry Creek, The simuRaneous flooding of these four streams was the primary cause of
<br />flooding on the South Platte River.
<br />
<br />Flood of 10 SeDtember 1933. Heavy rains of cloudburst proportions centered over the
<br />l.ittle Dry Creek basin and resuRed in the greatest flood of record, The estimated
<br />discharge of the stream during the flood was 10,000 cubic feet per second, Water rose
<br />in the residences as much as 3 feet above their first-floors, Heavy damages also were
<br />inflicted on business establishments and utilities in Englewood with some of the business
<br />buildings moved off their foundations by the high velocities, Floodwaters extended from
<br />two blocks north to a haff block south of the channel throughout its course through the
<br />urban area, Almost all of the street and highway bridges in Englewood were severely
<br />damaged and the total loss was estimated at approximately $180,000, Englewood Dam
<br />was later constructed on this stream, but a storm of this magnitude would still cause
<br />serious flooding,
<br />
<br />Flood of 3 Auaust 1956, A series of storms between 30 July and 3 August over the
<br />Denver area, including the Little Dry Creek basin culminated in more than 12 inches of rain
<br />being reported, for the period, in e:nglewood and the surrounding areas, Debris-blocked
<br />channels forced Little Dry Creek out of bank at several locations in Englewood and
<br />discharges exceeded channel cap~ICity below the town, flooding lowland areas, The peak
<br />discharge through town was limited to 1,000 cubic feet per second by operation of the
<br />Englewood Dam 9 miles upstream, Floodwaters inundated South University Boulevard
<br />and Bellevue Road, Debris blocked the bridges forcing the water over the roads, The
<br />bridge at Girard Avenue and Bannock Street - since replaced by a conduit had damage
<br />to its approaches, A small goff course near Santa Fe Drive had an estimatEld damage
<br />of $3,000. Flood damages were caused in Englewood by sidehill runoff as well as
<br />overflows of Little Dry Creek. Damages, including those incurred by sidehill nmoff, were
<br />greater than $30,000, ARhough the dollar damage of this flood can be considered minor,
<br />it is apparent that a flood threat still exists along Little Dry Creek even with Englewood
<br />Dam,

<br />4.1.4 BEAR CREEK
<br />
<br />Flood Historv, Flooding on Bear Crellk is typical of mountainous areas, with flash
<br />floods resuRing from intense rainfall over small areas, The source of a large percentage
<br />of floods occurring on Mount Vemon ancl Elear Creeks at Morrison, Colorado, are storms
<br />in the Genesee Mountain area, These floods are generally characterized by rapid
<br />concentration of runoff, unusually high peak discharges, and almost equally rapid recession
<br />time, Since 1876, 22 floods have been recorded in the Bear Creek basin ranging from
<br />relatively minor to major floods causing considerable property damage and frequent loss
<br />of life, Records indicate a total of 45 lives have been lost from floods in the basin,
