Impoundments are artificially constructed water bodies, and they share the basic ecological processes seen in natural lakes. We do observe differences, however, which are typically due to the fact that artificial water bodies are constructed for particular purposes. Witrynaan impounded stream is disturbed at the reach or val-ley segment scale (Frissell et al., 1986). Lake (2000) indicated that ﬂow cessation, mainly through drought, reduces water quality such that only the more toler-ant macroinvertebrate taxa are able to colonize and survive.
