Feasibility Study
Logan Irrigation District
Emergency Spillway Project
for the Prewitt Reservoir

Introduction (Need for the Project)

The Logan Irrigation District (LID) is the majority shareholder (54.8%) in the Prewitt Reservoir,
which is located in Logan and Washington Counties. The Logan Irrigation District, along with
minority shareholders the Iliff Irrigation District (25.8%) and the Morgan Prewitt Reservoir Company
(19.4%) form the Prewitt Operating Committee. Appendix A contains the Prewitt ownership and
the specifics about each entity. The Prewitt Operating Committee operates the Prewitt Reservoir
and its associated structures for the benefit of the landowners and shareholders by providing
stored water as a supplement to their direct flow irrigation water. The Prewitt Inlet Ditch diverts from
the South Platte River, just upstream of the Logan/Morgan County line. The water is stored in the
32,300 acre foot reservoir and deliveries are made either to the South Platte Ditch or directly to the
South Platte River for use by various ditches in Logan County or for exchange to water users in
Morgan County or for augmentation of wells within the service area. The Prewitt has operated at a
restricted storage of 28,600 acre feet for over 20 years and will be further restricted without the
construction of an emergency spillway. It is the desire of the Prewitt Operating Committee to once
again store the full decreed amount. It is felt that the construction of the emergency spillway is the
first step in completely removing the storage restriction. Additional steps may be a dam
stability/seepage study and addressing safety concerns with regard to wave action due to wind.
The Prewitt Operating Committee would like to begin c.onstruction on the spillway in the late
summer or early fall of 2006.

Project Sponsor

The LID is an irrigation district formed under the Irrigation District Law of 1905. Appendix B
contains the order creating the LID. The LID encompasses 12,818.9 acres and services 128
landowners. As with all irrigation districts, the LID Board of Directors certifies the levy, each
October, to the Logan County Commissioners and the levy is collected by the county treasurer
with property taxes. Failure to pay the levy sends the land into a tax sale. The Board of
Directors also has the power to limit the use of water until taxes are paid.

The LID is also part of a Governance Contract with the Iliff Irrigation District and the Morgan
Prewitt Reservoir Company. The Governance Contract, provided in Appendix C, addresses
each entity's financial responsibility with respect to the Prewitt Reservoir. Although the
Governance Contract was just officially entered into this year, the three owners of the Prewitt
have an excellent working relationship and the Prewitt has been operating this way for over 80
years. The LID Board of Directors at their March meeting agreed to be the sponsor of the
project and accept all financial responsibility for the purposes of this loan, while the Iliff Irrigation
District, and the Morgan Prewitt Reservoir Company agreed to be cooperating entities. The
minutes from the March meeting are presented in Appendix D.
