Lacustuary (original) (raw)

A lacustuary is a freshwater body of water where river and lake waters mix. Lacustuaries are nonmoving or "slack" water, although water in them can ebb and flow due to lake waves moving in and out, and the rising and falling of lake water levels. A lacustuary is that portion of a freshwater river or stream where lake water and river/stream water mix. The upper boundary of the lacustuary is that portion of the river directly affected by rising and falling water levels in the lake. Lacustuaries are generally nonmoving or "slack" water.
