I have a list of lakes in Central Florida with slalom courses and information on trophic levels of the lakes as well. I am an avid skiier and a real estate agent in Central Florida (mostly Orange and Seminole Counties with experience in Polk, Ocseola, Volusia and Lake as well). I specialize in Lakefront property and would be happy to help you. Let me know if you are interested in Central Florida and if not I could help you find a lakefront specialist in whatever part of Florida you are looking.
