In terms of outreach, the primary group that we work with is called the Ontario Federation of Anglers and Hunters, and I believe you're going to have one of their representatives speak here, if they haven't already. They try to educate boaters on how to prevent aquatic invasive species from spreading to inland lakes.
There are a couple of things we can do. Sometimes there are certain lakes that we know are either especially vulnerable to being invaded or they are likely the source of the new invasions going somewhere else. I will choose Lake Muskoka in Ontario, as an example. It is used by thousands and thousands of boaters. What we can do is post signs at marinas on that lake to warn people that they must take precautions to make sure they're not taking species out of the lake with them.
The other approach is, if you know you have a very vulnerable system, you can establish boat wash systems. This is now done in Minnesota and Wisconsin. They charge boaters a nominal fee—$5 to $10—and they will power wash their boats before they allow them to put them into new systems.
