I strongly suggest using native species. This is a lake and not
an isolated backyard pond, so there may be environmental regulations
that only allow native species as well. In my state, one is
prohibited against planting any non-native water lillies in
water that is part of a water shed.

Native species will be much likely to grow well since the area
has already proven able to support that species.
