[Ontbirds] St. Lawrence River water level

The area from Cornwall, above the dam, to Iroquois is experiencing its
lowest level in a lifetime according to seniors, down likely almost four
feet from the late December level. Once the Seaway was closed for the
season, the water level was reduced to the point that large stretches of
shallow nearshore habitat were exposed. Of course at this time there are no
shorebirds and waterfowl are in  low numbers here this winter. The effort
is intended to gradually lower the level of Lake Ontario. That could bode
well for places like Presqu'ile in the spring but time will tell how
effective this is in the near term or if this is a multi-year exercise.

The shipping season begins again in late March, around the time of the
arrival of Snow and Canada Geese and the Seaway level must be returned to
its previous state before that.
