Distribution
The compiled range includes portions of the Ohio and Mississippi basins and the Ouachita drainage. Historical records also include the Thames system in southern Ontario. A historical range statement should not be read as proof that every locality still supports a population today.
Gravel Habitat
Adults occur in creeks and small to large rivers where gravel forms riffles and runs. The substrate is an important part of the account. A river’s overall size alone does not explain whether a particular reach offers this bottom habitat.
Length and Observation
The reference maximum is eleven centimeters total length. At that scale, a measured photograph retaining the head, body and fins supports better comparisons than an unscaled image. The drainage and precise riffle location are also valuable when documenting a regional minnow.
Keep Historical Records Labeled
A published locality can be historically important without establishing current occupancy. Preserve the observation date when mapping Gravel Chub distribution.
