Section 10
Basin-Specific Options
A map of the locations of the conditional storage rights
in the Rio Grande Basin is shown in Figure 10-22.
Different colored circles are used to represent the total
volume of conditional rights that each location holds.
Most of the rights are held in the western portion of the
basin. This figure also shows the locations of potential
damsites in the Rio Grande Basin, as discussed in
Section 10.1.8.4 below.
Due to the limited availability of water in the Rio Grande
and compact limitations on post-compact reservoir
storage as described in Section 7, development of
conditional rights is not anticipated.
10.1.8.4 Rio Grande Basin Summary of
Restricted Reservoirs and Potential
Storage Sites
A few restricted reservoirs exist in the Rio Grande Basin
and are listed in Table 10-18. The total volume of
restricted storage in the basin is equal to 9,800 AF. Two
reservoirs are located in Water District 20 - the Bristol
Head #1 and the Continental Reservoirs. Reasons for
restrictions include inoperable outlet/poor general
~~
condition, causing a loss of 121 AF, and leakage that
causes a loss of 7,679 AF, respectively. Continental is a
pre-compact reservoir, which makes storage very
valuable; however, extensive work has been done on the
reservoir to reduce leakage, but with limited success.
The other restricted reservoir is located in Water District
21. The Terrace Dam has 2,000 AF of restricted storage
due to a deteriorated spillway. These reservoirs have
limited availability of physical supply and the owners do
not have the ability to pay for the needed improvements.
It is unlikely that these reservoirs will be rehabilitated and
the storage restrictions lifted unless a third party provides
funding.
Figure 10-23 also shows these data graphically. No other
water districts in the Rio Grande Basin have restricted
damsites.
Figure 10-22 shows the locations of potential damsites
identified by the CWCB in the Rio Grande Basin, along
with the conditional storage rights locations. Different
colored circles are used to represent the total volume of
conditional rights that each location holds. Potential
damsites are classified by total potential storage.
