EXECUTIVE REPORT SUMMARY

During the months of July and August of2002, various flood events occurred throughout
the state of Colorado. COImties that were affected include: Chaffee, Douglas, Garfield, La
Plata, Prowers, and Keith County in Nebraska. Keith County had a serious flood event in
July, and since it is close to the state of Colorado, it has been included in this report.
After the "Authority" section of this report, there are maps of both Colorado and
Nebraska counties, and highlighted maps, detailing the counties where each flood event
took place.

Each county experienced various degrees of flooding and damage. Keith County, in
Nebraska, had the most severe event of all counties that were studied. This event was the
only one to involve a death. The heavy precipitation caused different levels of damage to
each area. Most counties had: damage to structures, roads, culverts, bridges, public
facilities such as parks, crop damage, and personal property damage.

This report summarizes the 2002 flood events that took place in the state of Colorado and
surrounding areas. In no way is this report intended to review every event that took place
during the year, but specific events that the Colorado Water Conservation Board wanted a
closer look at. It investigates the key factors of a flood event such as: hydrologic and
hydraulic characteristics, storm facts and location, estimated flood damages, mitigation,
and a description of any areas that were underwater or impacted by the flood. Additional
support information found, such as pictures, maps, etc, was also included in each chapter.
