' 3. Water temperature of 5-8C by early July.
4. Adequate water flows.
5. Ability to sustain more than 500 adult fish and 22 kg/ha of
' biomass.
6. Ability to sustain reproduction.
2.3 Consult with landowners or agencies responsible for land management
of candidate habitats. Determine if the establishment of a
greenback cutthroat trout population in a candidate area would be
compatible with landowner or agency management goals.,
2.4 Prepare habitats listed in Tables 6 and 7 for reintroduction. Carry
out remedial actions necessary and appropriate to make candidate
waters listed in Tables 6 and 7 suitable for the introduction of
pure (Type A) greenback cutthroat trout. Aquatic habitats that have

' been selected for the introduction of greenbacks may be lacking in
some phase of preferred or essential habitat requirements. Special
emphasis should be given to Arkansas River projects (Table 7), since
only two stable reproducing populations currently exist in this
drainage.

pulation. If necessary and appropriate,
enhance candidate habitat to restore pool/riffle ratios,
riparian vegetation, spawning habitat, water quality and
protection from excessive disturbance.
2.42 Construct or improve barrier(s). Although natural fish
migration barriers are preferred, some areas may require the
' construction of artificial barriers or improvement of existing
barriers.
2.43 Remove all non-native salmonids. Use piscicides to remove all
non-native salmonids from the candidate habitats. Review the
' success of this removal and repeat the application of
piscicides, if necessary. Special emphasis should be given to
completing removal of non-native salmonids in candidate
habitats within the Arkansas River drainage. Allow treated
' habitats to remain fishless for a minimum of 6 months prior to
proceeding with the reintroduction of greenbacks and other
native fish (Task 2.5).

2.5 Introduce pure (Tvpe Al greenback cutthroat trout
Introduce pure (Type A) greenback cutthroat trout into the candidate
waters using the greenbacks most representative of the drainage
being stocked. Greenback cutthroat trout populations introduced
within the South Platte drainage (Table 6) should be established
with trout from Como Creek, South Fork of the Cache La Poudre River,
' Hunters Creek, Upper Hutcheson Lake, their descendants, or from yet
to be determined Type A South Platte populations.
Greenback cutthroat trout populations established within the
' Arkansas drainage (Table 7) should be established with trout from
Cascade Creek, South Fork Apache Creek, their descendants, or from
yet to be determined Type A Arkansas River populations.
2.51 Uae appropriate stocking rates for fish from wild populations.
Stocking rates for greenbacks from wild populations should be
100-200 sub-adults or adults per site, with 200 being the most
' desirable number. Removal of any greenbacks from pure (type A)
