The National Flood Insurance Program used the Floodway concept in
its rate studies for communities participating in the regular phase
of the program.

F. Flood Warning and Flood Forecasting System
The National Oceanic and Atmospheric Administration (NOAA) through
its National Weather Service Agency (NWS) , maintains year-round
surveillance of weather and flood conditions. Daily weather
forecasts are issued through the NWS and disseminated by radio and
television stations. A general alert to the danger of flash
flooding is one of the service provided by the NWS.

The Office of the Colorado State Engineer, Division of Water
Resources, in cooperation with the National Weather Service,
operates a state-wide flood warning system using 78-stream gaging
stations that are part of the Colorado satellite-linked water
resources monitoring network operated by the State Engineer.

G. Evacuation Plan
An "Emergency Evacuation and Operations Plan" would provide for
alerting the public of potential flooding, and coordinating
community and county services during an emergency. Planning
implementation during the time of an emergency requires cooperation
of the general public as well as local officials. This is
especially important for flood fighting, evacuation, and rescue
operations. Communication is extremely important during flood
alerts. Warnings issued through the NWS are disseminated by radio
to state and local officials.

RECOMMENDATIONS

The following recommendations are included for consideration in
reducing potential flood damages:

1. Sizing of culverts and bridges, based on flow data
available from this study, to assure that they have
adequate conveyance for storm runoffs.

2. Carry out periodic maintenance of bridges and
culverts to preserve their hydraulic capacity.

3. Implement design recommendations included in the
