STUDY OBJECTIVE

The purpose of the study would be to find locations which were technically,
environmentally, and politically feasible to store additional water. The Association has
more water rights than it is currently able to store there each of its stockholders would
see getting less water than they should. Tbe Association would like to consider
renovating some abandoned reservoir sites, construct a new reservoir, or enlarging some
of its existing reservoirs to store more water. The study will be used to determine
which options are best for storing more of their water rights and if storing more water
is feasible. .

STUDY PLAN

The study would involve field inspections of sites which the owners consider most likely
to be viable based on their assessment of basin and watershed. Initial investigation
would be a site visit with a hand level and tape to get an idea of feasibility. If the area
looks viable after the initial site visit, the US Forest Service would be contacted to see
if they had any overriding objections to development at the site. If not, a survey crew
would perform field work necessary to creat a topographic map of the existing
conditions. The survey data would be reduced and a topographic map developed of the
existing site and the proposed site with the dam. Calculations would include a volume
of water stored per foot of depth, volume of dirt needed to construct a dam of "x"
height, cost estimate for construction. and operations for the most viable heights, and a
cost per acre foot of water for the most viable options. This information would be
presented to the owner for their review with a report which includes the above data and
our analysis of the data. The Association is looking not for one correct answer but for
as many locations as possible which are feasible.

TASKS

1. Identify initially viable alternatives.

The Owners spend a great deal of time working on the Forest Service property in their
drainage. When they identify sites which might work to store additional water and has
the capacity to consistently fill with water, they discuss it among themselves and if
several of them think it has potential, they request that an engineering assessment be
made of the site. Sites are eliminated from further consideration if there are institutional
or environmental problems. This task is accomplished mostly by the Owners themselves
at no charge to the Association. As part of the initial identification, the Forest Service
is also contacted to see if they 'have any objections.. This takes a phone call and is
sometimes done by the Owners or can be dorie by the Engineer.
