1.3 POTENTIAL RESERVOIR SITES

I

Two of the four potential reservoir sites at which water availability was to be

investigated were indicated in the Request for Proposals while the remaining two

specific sites were to be selected as part of this study.

I

I

The pre-determined potential reservoir sites to be investigated were described as
follows:

1.

On the mainstem of the Rio Grande immediately above the confluence with Goose
Creek (referred to as Wagon Wheel Gap site).

I

2.

On the mainstem of the Rio Grande immediately below the confluence with Trout
Creek (referred to in previous studies as the Vega Sylvestre site).

I

I

The Request for Proposal identified two river reaches, as described below, for

location of the remaining two potential reservoir sites (one in each reach):

I

3.

On the mainstem of the Rio Grande from below the confluence with Goose Creek
to above the confluence with the South Fork of the Rio Grande.

I

4.

On the mainstem of the South Fork of the Rio Grande above the confluence with
Beaver Creek.

I

The nature of this study dictates that site selection be based primarily on factors

influencing physical and legal water availability rather than factors such as

geologic conditions, road relocation, land ownership, cost of dams or environmental

impact. Consideration of these other factors are left for subsequent studies.

I

I

Discussed below are 1) the Wagon Wheel Gap site, 2) the Vega Sylvestre site,

3) three potential storage sites on the Rio Grande reach from Goose Creek to South

I

Fork, and 4) three potential storage sites on the South Fork upstream of

its

confluence with Beaver Creek.

Based on the evaluations discussed below,

the

I

following four potential dam sites were included in the water availability analyses

for the Rio Grande Water Supply Study - Phase I.
