The Armbruster Report does not quantify the historical uses of tributary groundwater
rights and very limited records exist.
V. Uravan Water Rights Summary
V.A Miguel Power Company Canal Rights
In 1939, the Miguel Power Company Canal water rights were decreed in Civil Action
4641 for 240 cfs. 200 cfs were later abandoned in Case Number 83CW093. The remaining 40
cfs were transferred to the CWCB, as described in the Consent Decree in Civil Action 83-C-
23 84.
The historic diversions are shown in Table 7 of the Armbruster Report. There are extensive
periods of non-use, or no diversion records, between the early 1940s and the 1970s, and again
between the mid 1970s to the present.
V.B Johnson Ditch
By 1913, the Johnson Ditch had an original appropriation of 3.80 cfs (1891 - CA1627)
for irrigation, an enlargement of 3.75 cfs (1903 - CA 1627) for irrigation, an additional use of
26.2 cfs (1903 - CA 1621) for power and irrigation, and a second enlargement of 16.8 cfs (1913 -
CA 2533) for power. These rights totaled 50.55 cfs. In 1956, Civil Action 7107 limited the
Johnson Ditch rights to 25 cfs as against all pre-1956 rights, and 6 cfs for irrigation on the Club
Ranch Lands. This decree of the court also added the uses of domestic, milling, industrial, power
and other incidental uses year-round.
The historic diversions are shown in Table 8 of the Armbruster Report. The first recorded
diversion was in 1921. Little to no use, or no recorded diversions, occurred between 1921 and
the mid 1930s. The table indicates maximum diversion of the rights in the last half of the 1930s.
Sporadic diversions existed in the 1940s and 1950s, with a period of non-use between 1957 and
1973. Small amounts of diversion are indicated throughout the 1970s, 80s, and 90s.
V.C Mineral Camp Well
The Mineral Camp Well is located approximately .25 miles up Atkinson Creek, which is
tributary to the Dolores River at a point near the center of the Club Ranch Lands. The well was
decreed for 0.055 cfs in Case Number W0327, in 1971, for domestic uses. The Division of Water
Resources HydroBase database contains very limited records for the Mineral Camp Well usage,
stating no information was available in 1987, and that water was taken but no data available in
1989-1991, and no information was available in 1992 or 1993. Umetco was not able to supply
any use records, but has indicated that the well was dozed over during the reclamation of the
mine sites.
V.D Uravan Well No. 1, "G-Block", and No. 2, "F-Block"
The Uravan No. 1 Well (Uravan Well No. 1) was located in the G-Block of Uravan, near
the existing maintenance building. According to Umetco representatives, the well was used to
meet the culinary needs of plant personnel and Uravan residents, as well as limited industrial
