MEMORANDUM

TO: Regional Director, Bureau of Reclamation
Lower Missouri Region, Denver, Colorado

FROM: Assistant Field Supervisor, Fish and Wildlife Service,
Salt Lake City, Utah

SUBJECT: Narrows Unit, Pick-Sloan Missouri River Basin Program-
Fish and Wildlife Mitigation Lands

· This planning aid memorandum is provided in an effort to reach
an agreement among the concerned agencies regarding fish and
wildlife mitigation requirements for the subject project. It has
been prepared under the authority and in accordance with the
provisions of the Fish and Wildlife Coordination Act (48 Stat.
40l as amended; 16 U.S.C. 66l et. seq.).
~~~
Our June l6, 19B3 Fish andACoordination Act Report on the Narrows
Unit recommended a fish and wildlife management area of about
30,l5l acres to mitigate project impacts to fish and wildlife
habitat. However, in the Draft Supplement to the Final
Environmental Statement, your agency offer,ed to acquire and
develop about 2l,085 acres of land and water area which would
compensate for about 70 percent of the habitat losses. In an
effort to reach a compromise on the mitigation requirements, the
Colorado Division of Wildlife prepared a draft wildlife
development plan that would optimize wildlife habitat values on
the 2l,OOO acres.

The proposed management of the area will be much more intense
than previously indicated and as can be expected this will
increase the cost of development and the annual operation and
maintenance costs. However, the Colorado Division of Wildlife and
the Fish and Wildlife Service believe that the 2l,OOO acre
management area with the developments and the annual operation
and maintenance as proposed may not completely compensate for
impacts to fish and wildlife habitat from the construction and
operation of Narrows Reservoir in Colorado.

We have not determined the degree of increased compensation
provided by the more intense management of the 2l,OOO acres.
This will require a detailed analyses by the HEP team members of
the Habitat Suitability Index IHSI) and the useable acreage for
