Operate and maintain a total of 6 wetland enhancement projects on the Desert Wildlife Area that have been funded, in part, by the BPA. This contract will provide funding to operate and maintain the enhanced wetlands for one year to ensure they remain functional.

TD-1: The identified enhancement project is completed, which includes a recent BPA approved expansion in 2017. Annual
regular and recurring O&M activities and costs include the entire TD-1 project.  When operated in the fall, 9 wetland basins
are filled by diverting surface water from the Frenchman Hills wasteway into wetland basins. The Frenchman Hills wasteway
is considered a flow-through system that diverts irrigation water return flow from the wasteway into the project, with return
flows back to the wasteway downstream of the inlet structure. Current enhancements at the TD-1 Project include:
installation of 9 water control structures, construction of ditches and dikes for water management, sculpting wetland
basins to optimal depth for wetland obligate birds, island development, armoring 400 ft of dikes to protect against beaver and
burrowing mammals, seeding disturbed soil resulting from construction activities, and tilling wetland cells to promote desirable
moist soil vegetation.

TD-1: Regular annual operation and maintenance includes: coordination with BOR and Quincy Irrigation District,
inspecting/repairing enhancements, establishing desirable vegetation through varied methods, controlling undesirable
vegetation and noxious weeds, operating water control structures, inspecting and maintaining dike and water control
structure integrity and function, producing required BPA reports, and administering the contract.

TD-2: The Winchester Wasteway Project basins historically had a high enough water table that many would develop
into shallow ponds annually in the late summer/fall as the wasteway elevation was higher due to lessening agricultural
use, with a 3 week peak wasteway flow at the end of the irrigation season when the canals and laterals are being
dewatered. The Winchester project has an off channel inlet structure that feeds a single delivery ditch, which has a
number of control structures that feed the basins. Over the last three years, shifts in the wasteway channel and new
deep well irrigation adjacent to the project have combined to significantly affect our ability to seasonally divert water as
well as impacting the water table (we believe). It is not a flow through system, passive screens were installed at the
inlet. Carp are by far the most prolific fish in the wasteway. The enhancement project included: enhancement of 19
late-succession stage wetlands by excavation of organic material, construction of dikes to isolate enhanced wetlands
from the Winchester Wasteway, allowing for control of unwanted fish populations in the project wetlands, armoring over
1,200 feet of isolation dikes to protect against beaver damage and burrowing mammals, and seeding disturbed soils
resulting from construction activities.

TD-2: Regular annual operation and maintenance includes: inspecting and repairing enhancements, controlling
undesirable vegetation and noxious weeds, producing required BPA reports, and administering the contract.
Management of all project ponds will attempt to maximize habitat quality for waterfowl, shore birds, and other wetland species.

TD-3, TD-4, TD-5, and TD-6 were identified and included in the original project proposal as areas for potential migratory
and residential wetland associate species benefit through strategic management techniques.  Annual activities on
these sites have been limited to monitoring and treating invasive and non-desirable vegetation.  No significant
development of these sites has occurred to date.
