Water levels are low throughout California. I would not travel with an empty tank in the hopes that water will be available at my destination. Fill up before you leave home and don't worry about hauling "that extra weight" - your mileage sucks regardless.
As the Convict Lake campground is run by the USFS, I do not believe there is a potable water hookup available. They tend to only have a few spigots around the campground for filling dish pans, etc, not for filling RV water tanks.
Again, with this being a USFS campground and not a state campground, things are a bit more basic. If you have a reservation, there will be a tag on a pole at your campsite. There likely won't be a formal checkin process or kiosk - if there is a host, they might stop by to say hello. If no reservations, first come first sites will be paid for using an iron ranger.
According to one website, there are "challenging moutain bike trails" nearby at Rock Creek. It looks like otherwise bikes are limited to the roads and campground. There are a lot of hiking trails.
It sounds like kayaking would be good. The "no-wake" lake has a 6hp and 10mph speed limit. This is more of a fishing lake than a water sport lake - so it will be a quiet and calm lake.
