c. Release an instantaneous minimum flow of 5.5 cubic feet per
secon3 ( cfs) into Douglas Creek fram the Rob Roy Reservoir
outlet at all times.
d. Control maximum releases
to
the stream
through
the
Fob Roy
Reservoir
outlet works so as
not to exceed 130
cfs
except that
the natural flow may be
released if it
exceeds
130
cfs.
-- e. Annually
release through
the
Rob Ray Reservoir
outlet a
flushing
flow of 130 cfs
for
a minimum
of 72 continuous hours
(3 days)
coinciding with
the
period of
peak spring
runoff.
f. Maintain, as an instantaneous minimum, the maintenance flow or
the natural flow, whichever is less, immediately below the
diversion structure in each stream as listed in Table I.
g. Provide as a minimum the flushing flow or the natural flow
immediately below the diversion structures in each stream as
listed in Table I for a continuous 72 -hour (3 days) period
each year coinciding with the period of natural peak spring
runoff.

h. Install and maintain an acceptable measuring device immediate-
ly below each diversion structure on all streams listed in
Table I and immediately below the darns of Hog Park and Rob Roy
Reservoirs. The measuring,device shall be such that it can be
readily monitored by visual observation at all times.
i. On all streams not listed in Table I which have diversion
structures, provide a blanket minimum flow by releasing the
entire natural flow during the period of July 1 to November 1
or as late as adequate access is available.
j. Not 'at any time lower the water *level of Lake Owen below its
natural level. This water level is established at an elevation
of 8,948 feet.
k. Provide a screen of one- inch - square openings for the cutlet of
Lake Owen.
1. Annually prepare a full augmentation plan for Bamford Creek
(South Fork of Middle Crow Creek) for approval by the Forest
Supervisor. Flow releases into Bamford Creek during the first
year of operation will not exceed 1 cfs at each drop point or
total more than 2 cfs from all drop points. Releases after the
first year may be increased only if it is determined that higher
flows will not cause undesirable flooding or bank erosion.
Releases from all drop points totaling more than 8 cfs will not
be approved. Releases will not be made during the period of
peak spring runoff.
