Hello, Preparing to add two sections to this article with several sources.

Range and Habitat

Gammarus acherondytes is native to underground streams and waterways in Illinois. It has been recorded from five cave streams located in the Monroe and St.Clair counties. Fogelpole Cave, Illinois Caverns, Krueger-Dry Run Cave, Madonnaville Cave, and Pautler Cave in Monroe County. Along with Stemler Cave in St. Clair County. With Pautler Cave being closed down by the landowner. The largest population is recorded in the Illinois Caverns while no specimens were collected in Modannaville and Stemler Cave since 1986 and 1965 respectfully. Genetic evidence implies that none of these cave systems are interconnected due to the genomic pool of the populations being quite varied.

Threats and Conservation Efforts

Human pollution and runoff is the main threat to the species. With chemical pollution being the major threat to quality of water where they reside. Although research shows that Gammarus acherondytes breed all year-round. With juveniles constituting more than 50% of the population and strongly influence population density. Giving reason to believe that if they are allowed to remain undisturbed the population could feasibly bounce back to pre-pollutant levels.
