Says Candy I think it stinks that you cant go swimming there anymore. I used to love that as a kid. Says Elle The lake is pretty and clear sometimes, our girl lives there Says Cindy Play some mini golf at State Line Golf Center near Diamond Lake. This lake is so wonderful. Stay the night     at Riverside Campground, and for all you boaters, Griffith's Wawasee Marina is an outstanding marina nearby. A quick trip to North Branch Elkhart River right next door to Diamond Lake is a good idea.            Map Detailed Map Marinas Marinas on or near Diamond Lake Weather Local weather forecast
