Interesting, I wonder how widespread this is? (Trying to prevent ANY body contact because it's a municipal water supply.) And what their reasoning is?
Here (OKC, OK) they don't allow swimming but haven't said anything about us "falling in" - er, practicing our reentry skills! On a windy day the sailboarders are out. I get thoroughly drenched playing in the waves on my Outback. I've seen plenty of cats on their sides with the riders swimming around getting it back upright.
Other communities don't even restrict swimming. Though in many of our lakes everything you wear into the water is likely to come out a reddish-brown...
The muni supplies all use some pretty nice filtration / treatment plants, since the water in most of the lakes is never very clean to begin with (only a handful in the state actually have "clear" water you can see more than a few inches into) and can occasionally get downright nasty after a long hot summer with no fresh inflow.
Actually, that's more often the motivator to keep out of the water - not that the city doesn't want us in it, rather WE don't WANT to be in it!
