SUBJECT: Agenda Item 18a, September 14, 1984, Board Meeting--
Case No. 4-84CW119, Noel E. Andress
Ratify Proposed Statement of Opposition
The applicant is developing a subdivision approximately one
mile southeast of the Town of Crested Butte (See attached map) .
It consists of 14 duplexes and seven single family residential
units. Uses will include both in-house domestic and lawn and
garden irrigation. Diversions will occur from the Slate River via
both a well and a ditch. Sewage return flows will be via the
central system of the Skyland Metropolitan District to the East
River, above its confluence with the Slate River. The applicant
has filed this as a Plan for Augmentation, though the
appropriation date claimed for all structures is July 20, 1984.
The Board holds an appropriation for instream flow on the
Slate River for 23 cfs from Coal Creek to the East River. The
appropriation was made on March 17, 1980. All opposition has
withdrawn from the case and a decree is expected shortly.
The potential for injury comes from the applicant ' s request
for approval to divert out-of-priority. The applicant plans to
construct a pond of 3.2 acre-feet capacity which would fill under
the July 20, 1984 priority. Assuming the pond fills during the
runoff season with its 1984 priority, releases from the pond would
then be used to augment those out-of-priority diversions from the
well. However, because the in-house wastewater will enter a sewer
system which discharges to the East River, such use is 100%
consumptive so far as the instream flow appropriation on the Slate
River is concerned. This amounts to a depletion of 14.4 acre-feet
annually from the Slate River . The proposed augmentation pond is
not large enough to make up such depletions. The applicant sized
the pond to replace only the in-house consumptive use.
