Lake Ilo National Wildlife Refuge
Description: The Refuge contains prairie, grasslands, and wetlands. The uplands are characterized by gently sloping hills and terraces with creeks and an occasional slough. The average rainfall of 16.8 inches supports a prairie environment with a climate of hot dry summers, occasional thunderstorms, and cold winters. All of these factors influence the plants and animals that make Lake Ilo NWR their home.

Wildlife to Watch: The Refuge is home year-round to many species of wildlife and is visited by many migratory birds during the spring and fall. The Refuge checklist includes 226 birds, 36 mammals, 6 reptiles, 3 amphibians, and 11 fish species.

Large flocks of birds utilize Lake Ilo in the spring and fall. Peak concentrations can reach 100,000 waterfowl in the fall and 20,000 in the spring. The principle waterfowl nesting species are Canada geese, mallards, pintails, blue-winged teal, shovelers, and gadwall. Other nesting marsh and waterbirds include eared, western, and pied-bill grebes; double-crested cormorants; great blue herons; black-crowned night herons; and American bitterns. Shorebirds, such as killdeer, plovers, sandpipers, willets, yellowlegs, marbled godwits, American avocets, and phalaropes are plentiful during migration.

Some songbirds, such as meadowlarks, sparrows, and swallows, are easily seen from roads, while others are best found by hiking and quietly observing. Ring-necked pheasant are common, while sharp-tailed grouse and gray partridge are not as plentiful. The Refuge is home to white-tailed deer, badger, skunk, beaver, raccoon, mink, and muskrat. It is a special treat to see the less common pronghorn antelope, mule deer, coyote, and secretive weasel on the Refuge.

Special Tips: Located on the north shore of Lake Ilo, the Lake Ilo Park provides visitors with daytime facilities including tables, charcoal grills,litter receptacles, and a rest room. A 1-mile interpreted nature trailbegins in the park and winds along the north shoreline of Lake Ilo.
