Eastern Sand Darter
Eastern Sand Darter lives in medium-sized streams and larger rivers with clean sand and low gradient. Earliest reports placed this species in the Erie watershed and in the Salmon River of the Saint Lawrence watershed. The Salmon River population is secure but it has apparently declined in the Erie watershed. Its presence in the Oswegatchie, Champlain, Allegheny and tributaries of the Saint Lawrence farther west than Salmon River date from 1979, which suggests range expansion and possible increases in abundance. It is classified as Threatened; its status should be reviewed.
