 “Alex Takes Care of a Lake” is a creative work designed, written and illustrated by Joanne Diglio, a local children’s author, illustrator and teacher, and Pat Rector,  a county Environmental and Resource Management Agent.


One day a curious boy named Alex is kayaking on a lake when he comes across a water chestnut, an aquatic invasive species.  After learning about the harm aquatic invasive species cause nature, he decides to help take care of the environment.

This is the story of a curious boy who goes kayaking with his dad and asks questions, teaches about aquatic invasive species, ecology of lakes and the environment.  The curious boy learns what he can do to help and takes action.

Beautiful watercolor illustrations are included with the text.
