Lower Sacramento. Creek Reserveir Cempany - Reservoir Rehabilitation Project

Introduction

The Lower Sacramento Creek Reservoir Company (Company) is applying for a loan from the
Construction Fund in the amount of $371,300 for the Lower Sacramento Creek Reservoir
Rehabilitation Project (Project). The Lower Sacramento Creek Reservoir (Reservoir) is located in
Park County at an eleyation o.f 10,100 feet. The Reservo.ir is used for winter augmentatio.n water
storage for seyeral developments in the Fairplay area. The Reservoir receives water from
Sacramento Creek via the Platte City Placer Mine Ditch. The current Reservoir capacity is 26 AF,
however it has a decreed capacity of 37 AF. The clay lining originally installed in 1980 during
construction of the Reservoir began to fail soon after construction and continues to degrade. The
inability o.f the Reservoir to hold water makes it extremely difficult to use for augmentation purposes.
The Project will increase the Reservoir capacity and install a new PVC liner. The Project is expected
to cost $495,072 and be completed in the summer of 2005. See attached Project Data Sheet.

Backareund

The Company operates the Reservoir in Park County, Colorado, near Fairplay for the benefit of the
seven (7) shareholders by providing augmentation storage space to comply with their vario.us
decreed augmentation plans. The Company exchanges consumptive use water from the diversion
structure of the Guiraud;3T Ditch on the Middle Fork of the South Platte River to the Platte City
Placer Mine Ditch diyersion structure on Sacramento. Creek. The water is stored from May through
September and then released as required by the various decrees. The Reservoir was constructed
within alluvial aggregates and sealed with a clay liner. In subsequent years the liner has failed and
this keeps the Company from storing the decreed flows. The Company desires to install a 30 mil
plastic liner during the summer of 2005.
