The State of Oregon, which micromanages everything, has The Water Master. You have to get a permit to use your own water from a well, a pond, a spring, a stream, even rain barrels. The Water Master tells you your limit and you have to put a meter on to measure it. At my place in Curry county I captured a spring, diverted a small amount to a tank, overflowing to a horse trough which overflows on the ground and returns to the little stream. I had to pay $5000 in permits, am allowed to use 350 gallons a day for household use only. No irrigation allowed. This in an area of coastal Oregon where the annual rainfall is measured in feet.
Every year we have to fill out reports of monthly water use. At the home place in the next county we have water rights to the river and allowed 500 gallons a day. It rained 5 3/4' feet here last year. Everybody in the countryside hates the Water Master and probably falsifies their reports. Water Master - Sounds like the name of a boat doesn't it? I wish it would sink.
