The purpose of this report is to present information on the
flood hazards along the Blue River in the vicinity of
Breckenridge, Colorado. In general, the study area comprises
the flood plain of the Blue River only through the town of
Breckenridge. Peak discharges on the Blue River between
Goose Pasture Tarn and Dillon Reservoir are also tabulated.
Records indicate that two damaging floods have occurred in
recent years. Both of these floods were in 1965, since then,
Goose Pasture Tarn, a multi-purpose reservoir involving
recreation and municipal water, has provided a high degree of
incidental flood protection to the area downstream, but flood
damage out of the reservoir and from the tributaries of the
Blue River may still occur.

Studies made for this report show that floods larger than
those in the past oould ooour in the future in the study area.
This report contains information on past floods and maps,
profiles and cross sections that indicate the approximate
extent and depth of inundation from large floods that can
reasonably be expected to occur in the future. For the pur-
pose of this report these floods have been designated as the
Intermediate Regional and the Standard Project Floods.

This report was prepared by Leonard Rice Consulting Water
Engineers, Inc., of Denver, Colorado at the request of the
town of Breckenridge and in cooperation with the Colorado
Water Conservation Board. Funds for the study also came from
,VSummit County. It is intended that the report be used by the
town of Breakenridge, Summit County and other concerned
entities in such a way that flood hazard and future flood
damages are minimized. The report provides a basis for further
study and planning for optimum use and development of flood-
prone areas through zoning and subdivision regulations, con-
struction of flood control projects, or by a combination of
these or other approaches to reduce the flood hazards and
