1.0 INTRODUCTION

1.1 Puroose

This report was prepared to guide public and private entities interested in or affected by the
potential stocking of non-native fish species in off-channel ponds (public and private). Inundation
during flood events is possible at the pond sites and could affect endangered fish. The report
delineates the 50-year and 1 DO-year floodplains for the reach of the Yampa River designated as
"critical habitat" by the U.S. Fish and Wildlife Service (Service). The report allows interested
parties to determine preliminarily whether particular ponds are in the 50-year and lOO-year
floodplain of the Yampa River.

1.3 Related Flood Studies

The Federal Emergency Management Agency prepared Flood Insurance Studies (FIS') with
accompanying Flood Insurance Rate Maps for the City of Craig and for unincorporated Moffat
County, dated 3/84 and 8/82 respectively (References I & 2). The FIS' include peak flow values
for 50-year and 1 DO-year floods in the vicinity of Craig, Colorado, along with detailed floodplain
mapping. The Moffat County FIS also includes approximate floodplain information for an
additional one-half mile downstream of the limit of detailed study. The flow values from the two
FIS' and the accompanying detailed floodplain delineations have been incorporated into this
report

The U.S Army Corps of Engineers prepared a Flood Hazard Information Report for Craig,
Colorado, dated November, 1977 (Reference 3). The study includes detailed flood mapping and
