In low flow periods when the natural flows are less than these
minimum flows, no diversions will be made.

16. Issue: With regards to the Twin Lakes Transmountain Diversion
problem-:-the drying up of Lost Man Creek, and the Upper Roaring Fork,
and Lincoln Gulch or Lincoln Creek - we would urge the Bureau to see
to it that the Operating Principlea are strongly pursued to the end
that the Bureau secure from the existing and future Fryingpan-Arkansas
Transmountain Diversion waters the mentioned 3,000 acre-feet a year
to be released in the best possible way--either the Roaring Fork, or
Lincoln Gulch, Lost Man, or all three -- on an exchange basis with
the Twin Lakes Company to maintain a minimum stream flow.

Response:

Public Law 87-590, the authorizing act of the Fryingpan-Arkansas Project,
requires that the Project shall be operated under direction of the
Secretary of the Interior in accordance with the Operating Principles
adopted by the State of Colorado. The Operating Principles provide
for 3,000 acre-feet annually of water, to the extent that it is
available, to be delivered to Twin Lakes Reservoir and Canal Company
in exchange for equivalent releases from the headwaters of the Roaring
Fork River, which would otherwise be diverted through Twin Lakes
Reservoir and Canal Company's collection and diversion system. An
appropriate contract shall be executed whereby Twin Lakes Reservoir
and Canal Company shall refrain from diverting water whenever the
natural flow of the Roaring Fork River and its tributaries shall be only
sufficient to maintain a flow equal to or less than that required
to maintain the recommended average flows in the Roaring Fork River
immediately above its confluence with Difficult Creek. Paragraph II
of the Operating Principles contains the schedule of these minimum
flows as submitted by Fish and Wildlife Service and the Colorado
Division of Wildlife.

17. ~: The operating statement itself recognizes the prime
recreational value of the Fryingpan River as does Volume 2 of the
Draft Environmental Statement, wherein, L. M. Finnell reports, quote,
