<br />The Arkansas River has flooded in 1909, 1921
<br />1933, 1941, 1957, 1965 and 1974. Peak dis-
<br />charges for these events never exceeded the
<br />ten year flood peak discharge, However, these
<br />floods have disrupted highway and railroad
<br />traffic, disturbed communications, drowned
<br />livestock, destroyed agricultural land, roads,
<br />bridges and buildings. Several lives have been
<br />lost and numerous others injured,
<br />
<br />The 1921 flood caused the most damage as it
<br />reached a discharge of 19,000 cubic feet per
<br />second. The event flooded many streets and
<br />washed away several bridges, The floods of
<br />1909,1933,1941,1947, and 1965 washed out
<br />many bridges, including the railroad through
<br />Royal Gorge, and inundated as much as 200
<br />acres of land between Canon City and
<br />Florence.

<br />Canon City Flood plain
<br />Designation
<br />
<br />In 1968, the Soil Conservation Service
<br />mapped the 100 year flood plain. The flood
<br />plain included the area from the northern
<br />
<br />border of the city reaching south to the Arkan-
<br />sas River; and from Yale Place on the western
<br />border to Raynolds Avenue to the east. This
<br />area includes two (2) drainage basins: (1) the
<br />NortheaSt Canon Basin, and (2) the Orchard
<br />Avenue Basin. The study also designated ar-
<br />eas adjacent to the Arkansas river as well as
<br />the adjacent areas of streams that flow into
<br />the river from the South.
<br />
<br />In 1982, a Flood Insurance Study was per-
<br />formed for FEMA, including a flood map up-
<br />date. However, only the Northeast Canon
<br />Basin was re-mapped. The 100 year flood
<br />plain was reduced in this basin. The Orchard
<br />Avenue Basin was not updated and, therefore,
<br />presently has no FEMA designated floodplain
<br />within the City limits. The most recent flood
<br />has proven current mapping to be incomplete,
<br />since many areas outside the FEMA desig-
<br />nated flood plain were flooded in 1991 (i.e., in
<br />the Orchard Avenue Basin),
