Howdy and welcome, Dan.

I now know that MB is the abbreviation for Manitoba.

You're way North and way deeper that my experience, but you have an interesting situation. I may be able to ask some questions whose answers may help those better equipped to advise you. (Calling Dr. Perca.)

I think SMB will readily eat leeches. Most of the old timers here don't worry much about turtles. What species are they?

Are the two ponds filled by surface water or flow through ground water (like gravel pits). That's likely to make a difference. I would love to know what your dissolved oxygen profiles vs depth looks like in the heart of Winter. How thick do you think the ice will get, and how long a period are the ponds likely to be frozen over?
