Taxonomic Comments
Thought to have evolved from a stock of L. tridentata isolated in Miller Lake after the explosion of Mt. Mazama about 6,600 years ago (Kan and Bond 1981, Miller et al. 1989). However, subsequent data indicate a more ancient separation and a sister relationship with L. lethophaga (Lorion et al. 2000).

Number of Occurrences6 - 20
Rank Reasons
Formerly thought to be endemic to Miller Lake, Oregon, where exterminated in early 1950s through chemical control measures; recent surveys documented this species in several areas within and outside the Miller Lake subbasin in Oregon; no immediate threats. G3 rank was confirmed using NatureServe's Rank Calculator version 7.31.
Range Extent Comments
Formerly this species was thought to be endemic to Miller Lake (16 km northeast of Mt. Thielson), Klamath County, Oregon (Lee et al. 1980), where the species was last collected in the early 1950s. Recent surveys documented populations in Miller Creek, Jack Creek, and the upper sections of the Williamson and Sycan rivers, in the upper Klamath River Basin, Klamath and Lake counties, Oregon (Lorion et al. 2000, Page and Burr 2011).
Occurrences Comments
Lorion et al. (2000) mapped 8 collection sites; these represent probably a half-dozen subpopulations or locations (Oregon Department of Fish and Wildlife 2005).
Threat Impact Comments
Miller Lake was chemically treated with toxaphene by the Oregon Game Commission on September 16,1958 to eliminate tui chub and lampreys (Oregon Department of Fish and Wildlife 2005).

No immediate threats are known (Kostow 2002). Potential threats include impacts from stocked fishes, entrainment in water diversions, and impaired connectivity within and between local populations (Oregon Department of Fish and Wildlife 2005).
Ecology & Habitat

Habitat

Habitat includes clear rocky streams, and gravelly areas in Miller Lake; ammocetes occur in silt, mud, or sand (Page and Burr 2011). A nest in the Sycan River was a pitlike clearing on a gravel-cobble substrate in a sand matrix in water about 30 centimeters deep and about 3 meters from shore (Lorion et al. 2000).

Ecology

Adults live more than one year (Lee et al. 1980).

Reproduction

Spawning was observed June 10 at a water temperature of 12 C (Lorion et al. 2000). Relatively high fecundity (Miller et al. 1989).
