uses. The use records indicated an average of 0.267 cfs diversion for the period from May 13,
1959 through July 23,1973. From that time until December 31,1983, the Tabeguache No. 2 well
was used for these same purposes. The Uravan Well No. 1 permit, #2137F, limited production to
131 gpm. The well was decreed for 0.29 cfs in Case Number W0327, in 1971, for domestic uses.
The Uravan Well No. 1 was physically plugged and capped sometime around 2001. As
previously stated, the Armbruster Report did not quantify historical uses of water from the wells.
The Division of Water Resources HydroBase database contains very limited records for the
Uravan Well No. 1 and No. 2, stating that water was taken in another structure in 1981 and 1984,
water was available, but not taken in 1990-1991 and no information was available in 1992 or
1993 .
The Uravan Well No. 2 permit, #2370F, limits production to 500 gpm. The well was decreed for
1.1 cfs in Case Number W0327, in 1971, for domestic uses. The Uravan Well No. 2 is still fully
functioning. It is equipped with a pump and pipeline that delivers water to a standpipe on the
opposite side of the San Miguel River near the historic E-Block. The Uravan Well No. 2 has
been used for dust suppression. An average of 0.053 cfs was used for dust suppression from July
1, 2002 through December 31, 2007, and an additional 0.0005 cfs for soil conditioning during
reclamation of the site. These estimated numbers have been supplied by Umetco, as the
HydroBase database provides very little usage information.
V.E Tabeguache Wells, No. l & No. 2
The Tabeguache Wells are located approximately 1.5 miles up Tabeguache Creek on
Bureau of Land Management land. The wells historically produced water that was used for
municipal and industrial uses in Uravan. An existing pipeline, the Uravan Pipeline, connects the
wells to the standpipe located near the proposed location of the Ball Fields and then runs west
along the highway almost to the Uravan Well No. 2. The wells are no longer equipped with
pumps or electrical transformers. Case Number W2081 originally decreed Tabeguache Well No.
1 for 0.44 cfs, and Tabeguache Well No. 2 for 0.28 cfs. Both wells were decreed in 1973, for
municipal and industrial uses. Case Number 87CW0125 now limits the wells to 0.1 cfs total
diversion.
Very little historical use data exists for these wells. The Division of Water Resources HydroBase
database for Tabeguache Well No. 1 states that water was taken in another structure during the
years 1981 and 1983, used by Union Carbide in 1987, water taken but no data available in 1989,
water available but not taken in 1990-1991, and water taken but no data available in the years
1992 and 1993 for domestic use. HydroBase database records for Tabeguache Well No. 2 state
the same, except in 1992 and 1993 the well water was used for domestic and stock. As
previously explained, Umetco records indicate the well was used as a replacement to the Uravan
Well No. l to meet the culinary needs of plant personnel and Uravan residents, as well as limited
industrial uses, from July 23, 1973, until December 31, 1983. The Uravan Well No. 1 records
indicated an average of 0.267 cfs diversion for these uses.
Water quality tests were conducted on the Tabeguache Wells No. 1 & No. 2, as well as the
Uravan Well No. 2, in June of 2007. Tabeguache Well No. 1 generally has better water quality
