East Fork Mutual Ditch Company
January 27. 2004

Agenda Item 14b.

.

The East Fork Mutuallrriaation Company
The EFMIC is a mutual ditch company and a non-profit corporation registered in the State of
Colorado. There are 7 shareholders and 1,000 shares of stock. The EFMIC has the power to
set annual assessments to be paid by the shareholders, the power to cut off water deliveries to
shareholders that fail to pay their assessments, and the power to offer stock for sale to other
shareholders.

Water Riahts
The source of water for the Company is direct flow water rights from the East Fork of
Troublesome Creek. Water diverted at the Troublesome Creek headgate consists of a 75 cfs
peak flow with an August 5, 1959 appropriation. Records from the State Engineer's Office
indicate an average annual diversion of 8,000 acre-feet.

Proiect Description

Work Comoleted:

Due to a slide that occurred in the summer of 2003 the Company was forced to make
emergency improvements to their system. Based on evaluation of the site it was believed that
the failure was attributed to soil saturation when running ditch water and the failure of those
soils given the steepness of the adjacent slope.

.

The Company elected to repair the area by enclosing 1,060 linear feet of ditch with a 60-inch
diameter corrugated metal pipe. Within the new piped section of ditch the Company also had
to address two failed slope areas. The Company hired the services of Soil Nail launchers,
Inc., Grand Junction, Colorado to evaluate the site and to propose a remediation plan. Based
on the Contractors review and recommendation the Company elected to stabilize the two areas
by driving steel rods (soil nail launching) approximately 15-feet in length in a grid pattern. The
soil nails would connect to the stable underlying slope, therefore restricting the failed areas
from becoming any larger. This stabilization effort, however, would require additional slope
work in the future.

Installation of 1,060 linear feet of 60-inch diameter corrugated pipe = $63,924.35
Stabilization of failed slope areas = $38,000.00

Work In Proaress:

Upon completion of the improvements described above, the Company put the irrigation system
back in operation. Towards the end of the irrigation season, it was discovered that a number
of the pipe joints were beginning to leak, which in the long term could compromise the integrity
of the adjacent slope and increase the chance of another slope failure. Furthermore, the
success of providing additional slope stabilization work to the previous failed slope areas would
be greatly compromised as well.

The following alternatives were evaluated:
