The Upper Butte Basin Wildlife Area is approximately 9,600 acres and consists of three units: Llano Seco, Howard Slough, and Little Dry Creek. It is located within the Butte Basin, a low-lying area extending from the Sacramento River south and east to the Butte Creek drainage and southward to include the Butte Sink.
Historically, this basin consisted of a braided network of sloughs, channels, and oxbows resulting from the meanderings of the Sacramento River and Butte Creek, and comprised a significant portion of the wetland habitat available for wintering migratory birds. Today it is still considered one of the finest wetland habitat complexes in North America. The Wildlife Area was created to protect and/or restore some of these historical wetlands.
