INTRODUCTION
The City and County of Denver, acting by and through its Board of Water
Commissioners, has proposed the construction and operation of two major water
resource development projects:
1. Two Forks Dam and Reservoir (1.1 million acre-feet)
' 2. Williams Fork Gravity Collection System
The construction and operation of these proposed projects involves Federal lands
' and Federal permitting actions; consequently, the applicant has filed
applications for rights of way, and a Section 404 Permit with the Bureau of Land
Management (Bureau), the Forest Service and Army Corps of Engineers (Corps).
To assist the permitting agencies in their evaluation and conservation of
wildlife resources, this Fish and Wildlife Coordination Act Report has been
prepared by the U.S. Fish and Wildlife Service (Service) in cooperation with the
Colorado Division of Wildlife (Division) and the Nebraska Game and Parks
Commission (Commission), under authority of the Fish and Wildlife Coordination
Act (16 U.S.C., 661 et. seq.) (Act). The Division concurred with this report on
' October 7, 1987, (Appendix A) with some modifications and additions. The
modifications and additions have been included in this report. The Commission
concurred with this report for the nonlisted species discussion and conclusions
on October 5, 1987 (Appendix A).
Of the alternatives considered, the Two Forks Dam (Two Forks) with a 1.1 million
acre-feet capacity (one stage or two stage construction) and the Williams Fork
Gravity Collection System (Williams Fork) were selected by the applicant as the
preferred actions (Appendix B, Figure B-1). This report only addresses the
project alternatives for which the applicant has requested permits. Should the
permitting agencies decide to grant permits to any of the structural
' alternatives, then Fish and Wildlife Coordination Act compliance will be
necessary for these alternatives prior to permit issuance. Although other
alternatives are not discussed in detail in this report, comparisons of the
other alternatives are provided in the Mitigation section.
This document analyzes the effects of the preferred actions upon the potentially
affected fish and wildlife resources and recommends means of mitigating adverse
impacts. Impact analyses represented in this report include studies, data, and
evaluations conducted for the Corps or the applicant through the National
Environmental Policy Act (the Policy Act) process by private consultants, the
Forest Service, the Service, the Division and the Commission. As such, much of
the information used in the preparation of this Fish and Wildlife Coordination
Act Report has been excerpted without attribution from the baseline and impact
