Willard Bay is a man-made fresh water reservoir in the Great Salt Lake, in northern Utah. The bay was separated from the Great Salt Lake in 1964, and has since served as a source of irrigation, drinking water, and recreation for the northern Wasatch Front metro area.
Willard Bay is a 9,900-acre (40 km2) freshwater reservoir located in eastern Box Elder County, Utah, north-west of the city of Ogden, on the north-eastern floodplains of the Great Salt Lake.
The reservoir is operated by the Weber Basin Water Conservancy District and recreation activities are administered by Utah State Parks and Recreation. Fish in Willard Bay include black crappie, walleye, wiper, smallmouth bass, channel catfish, bluegill, and gizzard shad (which are unlawful to possess). At an elevation of about 4,200 feet (1,300 m), the area around Willard Bay features cottonwood and other high desert trees. In winter, the area is a wildlife area for watching nesting eagles.
