The Grass Valley Canal has been awarded a water right of 100 cfs (now limited by
diversion and use to 60 cfs) with priority right relating back to July 20, 1887. It is
the District's intention to fully utilize its 100 cfs water right. Harvey Gap
Reservoir has a Reservoir Priority of No. 5 relating back to April 1, 1891.

Project Description and Alternatives

The purpose of this project is to replace the transformer at the Silt Pumping Plant.
Replacement is necessary because X-Cel Energy is upgrading their transmission
line from 69kV to 115kV in the year 2006. Four alternatives were considered:

1. No action alternative.
2. Obtain our power from X-Cel Energy distribution line and upgrade
our pumps and motors to meet their voltage.
3. Replace our transformer and upgrade our pumps and motors.
4. Replace our transformer with a voltage configuration that will allow
us to upgrade our pumps and motors to a more common voltage at a
later date.

Alternative No. 1 was considered unacceptable since we would not be able to
pump from the Colorado River, thereby diminishing our annual water supply by up
to 5,000 acre feet.

Alternative No.2 was ruled out because of the increased power costs of nearly a
tripled amount. (Silt Water Conservancy District has a contract with Western Area
Power Administration (W AP A) to supply Colorado River Stbrage Project (CRSP)
electricity to our Project).

Alternative No.3 was ruled out due to the cost.

Alternative No.4 was chosen, since it will allow us to keep pumping water with
our existing equipment while allowing us to upgrade our pumps and motors at a
later date.
