Ouch!
Bare lie, just short of the water, tough pitch to a green that appears to have no grass upon which there is probably no bite. If you skull the shot, you're wet. If you somehow loft it with spin and it does check up, it'll roll all the way to the lake, given the apparent slope of the green (or is it brown?). If you land it past the flag, you'll be putting downhill and will probably also end up in the water anyway.
Pick it up, card an equitable 8, move on to the next tee and consider yourself richer for not having sacrificed an otherwise serviceable ball. You can thank me later.
