I think we emailed a little last year, I believe I went to school with your wife. Lake Malone has a 21.5' length and 150 HP limit. I have put my boat in a few times and never got a ticket, but thought you should know. Lake Malone is OK for wake boarding during the week, but is not the place to try and do it on the weekend. The ski area is too small and there is a lot of tube traffic. If you just want to go out on the lake and have a good time in the boat or swimming it is great though.
The closest ramp for the Green River would be in Central City. There is no dock however so getting in and out is a little tricky. Livermore would be the next closest, they have two ramps. I have not been there yet this year, but at least one of them should have a dock.
Green River is usually some of the best water you will ever find. Almost always glass or small ripples at the most. However, with the weather we have had this year there has been quite a bit of debris. I went out on it last Saturday and as long as you paid attention to where you were going it was fine. We have had no major storms since then so it should be all clear.
If you don't want to pull you boat up here, email me and I'll give you a pull. I can always use some more ballast.
