Basin-Specific Options
10.1.3.4 Arkansas Basin Summary of Restricted
Reservoirs and Potential Storage
Sites
Several restricted reservoirs exist in the Arkansas Basin
and are listed in Table 10-3. The total volume of
restricted storage in the basin is 71,261 AF. However,
two reservoirs comprise the majority of this total, one in
Water District 16 and one in Water District 67. In District
16, Cucharas #5 is in poor overall condition and has a
history of embankment movement resulting in a loss of
33,000 AF of storage. The Two Buttes Dam in Water
District 67 could store 31,465 AF if the hydraulically
inadequate spillway were repaired. These reservoirs
have limited availability of physical supply and the
owners do not have the ability, or in some cases desire,
to pay for the needed improvements given the limited
supply. It is unlikely that these reservoirs will be
rehabilitated and the storage restrictions lifted unless a
third party provides funding.
Figure 10-4 also shows these data graphically. While the
other water districts in the Arkansas Basin have
restricted reservoirs, Figure 10-4 shows that each of
these districts has less than 5,000 AF of potential
storage if all restrictions were addressed and full capacity
restored.
Figure 10-3 shows the locations of potential damsites as
identified by the CWCB in the Arkansas 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.
