' updates to these documents will guide the use of floodplain ponds.
These documents include: Reconnaissance Inventory and
-Prioritization of Existing and Potential Bottomlands in the Upper
Colorado River Basin 1993-1994 (Irving and Burdick 1995): Levee
Removal Strategic Plan (Lentsch et al. 1996): Genetics Management
Guidelines (Williamson and Wydoski (1994): Genetics Management Plan
(Wydoski 1995) and annual propagation plans prepared in accordance
with this plan: Augmentation Plan for the Razorback Sucker in the
Middle Green River 1996-1997 (Wydoski 1996): Stocking Plan for
Razorback Sucker in the Upper Colorado and Gunnison Rivers (Burdick
i et al. 1995): and all future stocking plans prepared through the
! Program.
11. Ponds are considered to be outside a designated floodplain if they
are naturally above the floodplain in question or if they lie in
the floodplain in question but have FEMA approved dikes
functionally separating the pond from the floodplain.
12. Concurrent with implementing these stocking procedures, the
Recovery Program will conduct a peer-review study to evaluate the
effectiveness of the Interagency Standardized Monitoring Program
(ISMP) to detect changes in the survivability and/or abundance of
routinely stocked fish. Unless the study demonstrates that the
ISMP is effective for tracking nonnative fishes, a program would
have to be implemented to do so. If it is determined, by peer
review analysis by the respective State and the Service, that
nonnative fish escapement is occurring from an approved location,
then routine stocking of that species in that location would be
discontinued. Subsequent stockings at that location would then
require case-by-case review by the State wildlife agency and the

j Fish and Wildlife Service (until the escapement problems are
corrected) to ensure that escapement has been adequately addressed.
I IV.
1. Nonnative fish species that occur and are managed by stocking in
the Upper Colorado River Basin can be routinely stocked (i.e., are
not subject to procedures outlined in Section IX) in the
locations/situations identified within this section. Stocking of
nonnative fish species in these locations/situations are considered
to be consistent with recovery of the endangered fishes.
Explanations of the terms/acronyms are provided in Appendix B.
2. Trout can be routinely stocked directly into riverine habitats
upstream of critical habitat. Stocking of trout into private
floodplain ponds is also allowed. Stocking of trout within
riverine portions of critical habitat is not allowed under these
procedures.
