• Recreational Experience
• Sediment
• Tribal Resources
• Rainbow Trout Fishery
• Riparian Vegetation
• Water Quality and Food Base (added, part of KA)

• Natural Processes: Not used (is an evaluation of above resources as related to “natural” benchmarks)

Humpback Chub

Ongoing actions:

• Translocations of humpback chub into tributaries of the Colorado River in Marble and Grand Canyons
• Spring and fall humpback chub population estimate
• Control or removal of nonnative fish in tributaries prior to chub translocations
• Humpback chub refuge population at a federal hatchery
• Ensure that a stable or upward trend of humpback chub mainstem aggregations can be achieved by:

1. Annual monitoring of the Little Colorado River humpback chub aggregation (e.g., juvenile chub monitoring parameters).
2. Annual monitoring in the mainstem Colorado River to determine status and trends of humpback chub.
3. Periodic surveys to identify additional aggregations and individual humpback chub.
4. Evaluate existing aggregations and determining drivers of these aggregations.
5. Explore means of expanding humpback chub populations outside of the Little Colorado River Inflow aggregation.

• Disease and parasite monitoring

New actions:

• Feasibility study for translocation of humpback chub into Upper Havasu Creek (above Beaver Falls).
• Evaluate other tributaries for potential translocations.

Razorback Sucker

Ongoing actions:

• Larval and small-bodied fish monitoring.

Actions to benefit all native aquatic species

Ongoing actions:

• Investigate the possibility of renovating Bright Angel and Shinumo Creeks with a chemical piscicide.
• Remove brown trout (and other nonnative species) from Bright Angel Creek and the Bright Angel Creek Inflow reach of the Colorado River, and from other areas where new or expanded spawning populations develop.

New actions:

• Explore the efficacy of a temperature control device at the dam to respond to potential extremes in hydrological conditions due to climate conditions that could result in nonnative fish establishment.
• Preventing the passage of deleterious invasive nonnative fish through Glen Canyon Dam.
• Fund the NPS and GCMRC on the completion of planning and compliance to alter the backwater slough at River Mile (RM) 12.
• Develop a plan for implementing rapid response control efforts for newly establishing or existing deleterious invasive nonnative species.
• Experimental use of TMFs to inhibit brown trout spawning and recruitment in Glen Canyon

Southwestern willow flycatcher and Yuma Ridgway’s rail

• Conduct Yuma Ridgway’s rail surveys
