Can we still stage on the B road at the harbor, ride down the lake bed and water skip the river? It's not that far from Chatter.
LOL! Every notice how it looks a lot shorter than it is? FYI, they drop the reservoir from 30-40 ft in the winter. If you hit an ice shelf or a large chunk gives way as you ride over it, even a 20 ft drop is a long way down at 20 mph, nevermind if you slam your face into the other side of the ice shelf that didn't break off or end up underneath something. I have water skipped lots and its not crossing the water that's the hard part, its getting across the snow. "A few" stumps doesn't even begin to cover it, that place is a minefield. Later in the season as things get soft that snow is all rotten on the bottom, at times you will leave a 4ft trench behind you just from where it starts to punch out on the bottom or where the meltwater runs underneath and melts it away leaving big sinkholes that you only find when you drive over them.....it gives me the willies thinking about where you could land if you fell into one.
Seriously, I know it looks doable but it would be a wide open run the whole way and not good at all if something went wrong. Its not advised to try it. If you break something while sledding don't even think about trying to tow across the lake.
Besides all the safety issues, there is legislation for motorized vehicles and their use on water bodies and drinking water reservoirs. Not sure its application to the Kinbasket but I would realllllllly hate to be handed a ticket from the MOE or DFO for violation, because the fines can be pretty hefty. Just because they boat on it doesn't mean anything, your sled has coolant that a boat doesn't and sometimes this can make it classified as a potential contaminant (compared to fuel and oil) so boating regulations may not apply as this would make your sled exempt from the regs and open to all sorts of liability. The DFO are not people you want to mess with. They are the only government branch besides the RCMP that are allowed to possess sidearms and they have huge power.
If you sink your sled they can fine you for introducing a contaminant into the water, which isn't good, you don't want to get mixed up with DFO or the CCG (coast guard), both of which will have jurisdiction in this area, along with MOE since anything with "navigable waters" is under their umbrella as well. Not to mention that you could drown, lose your sled, and surely would find yourself on the news, as well as Like portgrinder says, once you get across the lake, you probably will be on gravel anyway.
Hope that helps.
