Coregonus prognathus Smith: a nomen dubium
Thomas N. Todd
1981, Copeia (1981) 489-490
No unique phenotypes were observed among the specimens and no single species clearly dominated the samples. I conclude therefore that the species Coregonus prognathus has no taxonomic validity. Because of the poor condition and uncertain identity of the holotype, Coregonus prognathus should be considered a nomen dubium....

Water levels in most wells measured in September 1981 are equal to or higher than in May 1981. Levels averaged about 26 feet higher in the southern part of the area and...
