Like Mipcar has suggested a handheld and a ship installed would be the best way. I have both and regularly get 30-40NM range from the mast installed unit, and recently had clear communication with another vessel 80NM away. In comparison the handheld is almost a toy, I doubt if I would get a range of much more than 5NM (it is an ICOM IC-M33). Not sure how big your lake is, however if it was much bigger than 5NM a handheld will only reach other boats around you.
Another options is your cell phone. I am in the process of getting a phone with an external aerial. A friend recently had good (20NM) reception from using this option, however it's hard calling up the boat next door, unless you know their number.
