Seminoe is a big reservoir with 180 miles of shoreline fed by two rivers: North Platte and Medicine Bow. Vegetation in the are is mostly of the high desert variety including yucca, greasewood, sagebrush, salt sage, willows, and marsh grasses. No trees, except pine and junipers that can be found on the mountains near the dam. There are also some sand dunes.

Seminoe is the first in series of reservoirs on the North Platte River (next reservoirs are Kortes, Pathfinder and Alcove). When driving to Seminoe State Park from I-80 you can visit Fort Fred Steele State Historic Site.
