  All the aquatic and marsh-loving plants just mentioned,
with many others of similar habits, continue to flourish in or
about the lake whenever the local conditions suit their
requirements. Indeed they are rather more abundant and
widely distributed now than they were twenty or thirty years
ago for although the water is higher now than formerly it is
kept at a more uniform level in summer and the shore lines
are becoming better and better defined and established.
