3. The following conditions apply to stocking of nonnative fishes
within the 50-year floodplain :
A. Private Ponds: The stocking of largemouth bass, bluegill,
black crappie, and triploid grass carp for ponds within the
50-year floodplain in the Upper Colorado River Basin will
require that the ponds be bermed to FEMA standards to the
50-year floodplain. If an outlet exists on the pond, the
outlet must be screened prior to stocking. The stocking plan,
screening, and berming must be approved by the appropriate
State wildlife agency and the Fish and Wildlife Service. Once
approved, future stocking of that pond is considered routine,
not requiring further approval. Screens and berms will be
inspected annually by State wildlife agency personnel. If
berming or screening fail to control escapement of nonnative
fishes, then that pond will require a case-by-case review prior
to any additional stocking.
B. Public Waters: Stocking of nonsalmonid, nonnative fishes in
public waters within the 50-year floodplain will not occur
except for the following exceptions.
(1) The State of Colorado has developed lake management plans
or stocking plans for the following waters in the Upper Basin,
excluding the San Juan River Basin, that have been approved by
the Service since the inception of the Recovery Program.
Stocking of approved species into the following these waters
will be routine:
Rio Blanco Reservoir, Colorado
Purdy Mesa Reservoir, Colorado
Mack Mesa Reservoir, Colorado
Chipeta Lake, Colorado
Crawford Reservoir, Colorado
McPhee Reservoir, Colorado
Harvey Gap Reservoir, Colorado

(2) Routine stocking of largemouth bass, bluegill, black
crappie, and triploid grass carp can occur in Corn Lake, the
upper Connected Lakes, and Duke Lake once the Colorado Division
of Wildlife and the Service have approved for these waters: 1)
berming to FEMA specifications to functionally remove them from
the 50-year floodplain: 2) screening of the outlets: and 3) the
Lake Management Plans. These waters provide important
recreational fishing opportunities for kids and others through
programs such as Pathways to Fishing.
1 In areas where the 50- or 100-year floodplain boundary are not known,
the point 5 feet above the OHWL may be used as the boundary location
for the 50-year floodplain and 5 % feet above the OHWL can be used to
represent the 100-year floodplain (see Appendix B).
