According to Lyons, Cochran and Fago (2000), the species in "has become less
common in southern Wisconsin in recent years" and "has declined greatly in
abundance and possibly disappeared" from at least two lakes.

Lyons, Cochran and Fago (2000) credit an aquarist (Ray Katula) with
discovering a new population, and acknowledge that the species is more
widespread than Becker (1983) indicated, but also note that the Coon Creek
population may be gone, and that a resampling of the Sugar River tributary
in Rock Co. failed to yield specimens.
