Loloff Reservoir - Weld County
Ownership: None Listed
Description: This small reservoir on a private farm seems to be one of the most reliable shorebird sites in the county in both spring and fall. It can also fill with waterfowl and gulls. Indeed, it sometimes can be utterly spectacular. From 2011-2013 alone, it has had Short-billed Dowitcher, Tundra and Trumpeter Swan, Glossy Ibis, Mexican (Mallard) Duck, Sabine's Gull, and large flocks of Whimbrel.

The ponds along CR 59 nearby are mostly marsh with a fair bit of open water and some shorebird potential (producing recent records of Short-billed Dowitcher and Dunlin). These ponds can be excellent, having produced Colorado's first Fulvous Whistling-Duck in 1990 as well as Eurasian Wigeon in 2013. Among the more mundane, this is a good spot for Marsh Wren and Virginia Rail, plus scads of Great-tailed Grackles breed in the marsh. 
Habitat: Pond/Lake/Reservoir, Marsh
Directions: Take US 34 to CR 59 (9.5 miles east of the US 34/85 intersection in Greeley, and 27.5 miles west of I-76), and go south for 1.7 miles to CR 50. Take a right (west) onto CR 50 and travel 1 mile to CR 57. Loloff Reservoir is just north of this intersection.
