You are also supposed to not wash dishes directly in the water source - take it away to do the washing and rinsing, disperse the "dirty" water rather than dumping all in a single spot. Use only biodegradable soap, if any.

Do not do #1 or #2 within that 200 feet of the water source, either.

I have seen people break all three rules - they become very irate when you point out to them what you know the ranger told them when the permit was issued. In some places it's 50 feet, in others 100 feet, apparently where you are it's 200 - and people ignore even the 50 feet.

One of the reasons we have to filter water - people don't pay attention to things like this, water sources are contaminated.

And yes, in some places, the water rises quickly.
