Red Marker Silvies River Floodplain
An area of flood-irrigated meadows and haylands between Burns, Oregon and Malheur Lake in Harney County, southeastern Oregon.

Location: The Silvies River Floodplain is an area of flood-irrigated meadows and haylands 20 miles southeast of Burns, draining into Malheur Lake in southeastern Oregon.

Description: The Silvies River area was historically a shallow, slow moving river system of sloughs and swales interspersed with meadows. In wet years, the flooding banks of the Silvies River creates an extensive wetland system in the valley. This region is characterized by miles of privately owned grasslands and open pasture, with some sagebrush uplands scattered throughout.

Ornithological Highlights: Silvies River supports nesting Sandhill Crane, colonies of Great Egrets, White-faced Ibis, Double-crested Cormorant, Black-crowned Night Heron, Snowy Egret, and hundreds of nesting shorebirds and ducks. Peak migration counts include 300,000 spring-staging Snow and Ross' Geese, 1,000,000 ducks, 10,000 swans, 12,000 Lesser Sandhill Cranes, and 300 spring-staging Bald Eagles.
