The UDFCD published a report on the South Platte River in September 1985
covering the Denver Metropolitan Area from Sand Creek upstream to Oxford
Avenue, Discharges and flood elevations from this report were used in
this revised study (Reference 44).

A Flood Hazard Area Delineation report for Clear Creek was published in
1979 (Reference 22). That report contained hydrologic and hydraulic
data for fully developed basin conditions; those data are in agreement
with the analyses used in this study.

.

A Special Flood Hazard Information report for Bear Creek was published
in 1972 (Reference 82). That report included a hydrologic analysis of
Bear Creek using 1970 channel conditions and development. The report
was completed before the construction of the Bear Creek Dam; therefore,
discharges and flood elevations determined in the report do not reflect
present-day flooding conditions,

The COE prepared a hydrologic analysis for Bear Creek downstream of Bear
Creek Dam (Reference 24). Peak discharges were developed for different
basin conditions. The discharge values developed using full basin
development conditions are in agreement with the discharges used in this
study.

A Flood Hazard Area Delineation report for Bear Creek was published in
1979 (Reference 48). Hydrologic and hydraulic data for fully developed
basin conditions, which were presented in that report, were utilized in
this study.

A Flood Hazard Area Delineation report for Cherry Creek was published in
1976 (Reference 10), Data from that report were utilized wherever
possible in this study; however, channel improvements completed in 1980
and 1981 necessitated recomputing the water-surface profiles in some
areas.

The UDFCD published several reports on Westerly Creek, The earliest
report, published in 1976 (Reference 83), was superseded the next year
by a Flood Hazard Area Delineation report (Reference 64) and a Major
Drainageway Planning report (Reference ll). The 100-year floodplain
boundaries shown in this study reflect some recent channel improvement
and will therefore not agree with the previously published reports.

The UDFCD published a 1978 Flood Hazard Area Delineation report which
covered Coon Creek (Reference 66). The 100-year floodplain boundaries
for Coon Creek presented in that report were used in this study,

The UDFCD published two reports on Lakewood Gulch, The hydrologic
analysis presented in the 1976 Major Drainageway Planning preliminary
report (Reference 39) was used in the 1979 Flood Hazard Area Delineation
report (Reference 53). The hydrologic and hydraulic data presented in
those reports were utilized in this study.

The UDFCD published Flood Hazard Area Delineation reports for Dry Gulch
(Reference 12) and for Harvard Gulch, West Harvard Gulch, and Dry Gulch
