While we are on the topic of lotic (flowing) vs lentic (still) waters, let me
throw out an associated question. Here in Texas, we do not have any natural
lakes (OK, maybe one but even that is open to debate.). All of our "lakes"
are actually reservoirs created by placing a dam across a river. The
resulting reservoirs, are they considered lentic or lotic? I haven't been
able to find any definitive description in the literature but I have developed
my own theory which is that reservoirs are a combination of lotic and lentic
systems. The area of the original river channel usually shows some sort of
current and therefore has lotic qualities while the reservoir edges tend to
more lentic in nature. Does anyone have anyone have any other thoughts on
interpreting this situation?
