Platte River Restoration Efforts
Background
The Platte River system, located in the states of Colorado,
Nebraska, and Wyoming, supports 15 major dams and
reservoirs, which provide water, hydroelectric power,
irrigation, flood control, and recreation for about 3.5
million people, as well as habitat for fish and wildlife.

Implementation Program, 2018, adapted by CRS.
Irrigation in the Platte River system was developed in the
early 1970s. After passage of the Endangered Species Act
(ESA) in 1973, several species from the region were listed
as endangered or threatened. As a result, water conveyance
infrastructure in the system was subject to Section 7
consultation under the ESA. The U.S. Fish and Wildlife
Service (FWS) consulted with federal agencies managing
projects in the Platte River to determine how projects could
operate without harming federally listed species. FWS
found that some federal actions that depleted flows in the
Platte River were likely to jeopardize one or more listed
species (i.e., target species), including the endangered
whooping crane, endangered pallid sturgeon, threatened
piping plover, and formerly listed interior least tern. The
challenges between implementing hydropower-related
projects and conserving species listed under the ESA
ultimately led to an agreement among stakeholders.
In 1997, the Secretary of the Interior (Secretary) and the
governors of Nebraska, Colorado, and Wyoming signed the
Cooperative Agreement for Platte River Research and
Other Efforts Relating to Endangered Species Habitat
Along the Central Platte River, Nebraska. Under the
agreement, a Governance Committee was created-made
up of 10 voting members, including the signatories, water
users, FWS, the Bureau of Reclamation (Reclamation), and
environmental groups. The committee was charged with
creating a program to improve and maintain the habitat of
the four target species on the Platte River and to ensure

compliance with Section 7 under the ESA for certain
existing and future water operations activities in each state.
This program, created in 2007, is the Platte River Recovery
Implementation Program (PRRIP).
PRRIP
The PRRIP covers the north, south, and central Platte Basin
(Figure 1). The program's purpose is to implement portions
of the FWS recovery plans for target species habitat. To do
this, the PRRIP has three main elements: (1) increasing
flows in the central Platte River during certain periods;
(2) protecting and restoring habitat for target bird species;
and (3) accommodating new water-related activities (e.g.,
water storage, diversions, and conservation). These
elements are addressed in three plans, each with a set of
goals and milestones.
* The Water Plan aims to improve flows and maintain
habitat for all target species in the central Platte River
area through incentive-based water projects that provide
an additional 130,000-150,000 acre-feet (af) per year
toward target flows for the environment, which FWS
previously established. (These improvements generally
are known as reduced target flow shortages.)
* The Land Plan aims to protect and, where appropriate,
restore 10,000 acres of habitat during the PRRIP's First
Increment. The Land Plan's long-term objective is to
acquire, restore, and maintain 29,000 acres of habitat for
listed species along the central Platte River.
* The Adaptive Management Plan provides a systematic
process to monitor the implementation and measure the
success of PRRIP activities. It applies the information
learned to improve management decisions and the
survival of all species and to avoid impacts to species'
habitat.
The PRRIP is being implemented through the central
Governance Committee, which oversees program staff and
other combined federal and state efforts (Figure 2). The
program is to be conducted in increments. The First
Increment initially covered a 13-year period, from 2007
through 2019. This increment was extended for another 13
years, through December 2032, with some changes to the
plans. Subsequent increments are to be implemented
through cooperative agreements between the Secretary and
the governors.
Federal Role
The Consolidated Natural Resources Act of 2008 (P.L. 110-
229, Title V, §515) authorized the Secretary, acting through
Reclamation and in cooperation with states and federal
agencies, to implement the PPRIP's First Increment from
