Lake Lowell is managed by both the Bureau of Reclamation and the US Fish and
Wildlife Service. Part of the Boise Project this 14.5 square mile (9,800-acre)
reservoir with 28 miles of shoreline lies within the Deer Flat National
Wildlife Refuge. Boating, fishing, and wildlife viewing are the major
recreation activities at Lake Lowell, located 5 miles southwest of Nampa. Lake
Lowell, originally called Deer Flat Reservoir, was the first storage reservoir
completed for the Boise Project, one of the earliest Reclamation projects.
Historic features include the embankment dams which are on the National
Register of Historic Places. The embankments include the headworks for four
canals. Repairs made to the dams in 1938-39 by the Civilian Conservation Corps
include rustic lava-rock parapet walls with decorative designs embedded in
them. Lake Lowell is a great birding spot with over 200 recorded avian
species. Spectacular bird concentrations occur on the lake during peak
migration periods. During state seasons, upland birds, ducks, coots, and
mourning doves may be hunted on the East Side and South Side Recreation Areas.
Available fish species include rainbow trout, largemouth bass, smallmouth
bass, crappie, yellow perch, bluegill, and bullhead and channel catfish.
Season open year-round. Reservoir acre feet and total reservoir capacity and
cubic feet/second release rates for rivers below Boise & Payette River Basins
reservoirs and select river locations are updated daily and graphically
provided. Power craft permitted April 15 through October 1. Site offers boat
ramps and docks, and parking at the upper and lower dam sites and at the
visitor center. The refuge Visitor Center is open all year on Monday through
Friday from 8am to 4pm and Saturdays from 9am to 4pm. For additional
information, please see the  Deer Flat National Wildlife Refuge or  The Bureau
of Reclamation's information on Lake Lowell.

Lake Lowell

Deer Flat National Wildlife Refuge is one of the oldest refuges in the
National Wildlife Refuge System. It was established in 1909 to designate the
new irrigation reservoir as a refuge and breeding grounds for migratory birds
and other wildlife. The refuge now serves as an urban oasis for both wildlife
and Treasure Valley residents and visitors.

Deer Flat National Wildlife Refuge has two units–-Lake Lowell and the Snake
River Islands. The Lake Lowell Unit encompasses over 10,500 acres, including
the almost 9,000-acre Lake Lowell and surrounding lands. The Snake River
Islands Unit contains over 1000 acres on 104 islands. Refuge islands are
distributed along 113 river miles from the Canyon-Ada County Line in Idaho, to
Farewell Bend in Oregon.

The Refuge protects a wide range of wildlife habitats: the open waters and
wetland edges of Lake Lowell, the sagebrush uplands around the lake and the
grasslands and riparian forests on the Snake River islands. The variety of
habitats makes the refuge an important breeding area for resident and
migratory birds, including providing one of the few nesting areas for western
and Clark’s grebes in Idaho. The refuge is also a significant resting and
wintering area for birds migrating along the Pacific Flyway, including
spectacular concentrations of mallards and Canada geese. Because of its value
to birds, Deer Flat National Wildlife Refuge has been declared an Important
Bird Area by the National Audubon Society.

The refuge welcomes diverse communities to connect with nature and each other
through free educational and outdoor recreational experiences.

The Owyhee Project lies west of the Snake River in Malheur County, Oregon, and
Owyhee County, Idaho. The key feature is the Owyhee Dam, on the Owyhee River
about 11 miles southwest of Adrian, Oregon. The dam is a concrete, thick-arch
structure which was designed to carry about three-fourths of the water load by
arch action, and the remainder by gravity action. The dam rises 417 feet above
foundation in the river section and, at the time of its construction
(1928-1932) was the world's highest dam. Owyhee Dam became a proving ground
for theories being developed to assist with the design and construction of
Hoover Dam, whose unprecedented size, 300 feet higher than Owyhee, required
totally new construction methods.This 52-mile-long, 13,900-acre reservoir is
located approximately 50 miles south of Ontario. Vehicle access is limited to
the dam gravel road access to Leslie Gulch, Dry Creek, and Red Butte. Owyhee
Irrigation District operates a visitor information center located in the
historic construction office below the dam. Displays primarily focus on
construction of Owyhee Dam and Irrigation Project. The facility is handicap
accessible. Available fish species include largemouth bass, smallmouth bass,
crappie, rainbow trout, brown bullhead, and yellow perch. Season open year-
round. For reservations call 1-800-452-5687.
