Welcome to the wacky, wonderful world of water law-every state is different and there are vast differences as you move west.
Washington recently had a state Supreme Court decision that, in effect said, ‘just because you drill a well (with state Dept. of Ecology permission btw) your aren’t necessarily entitled to take any of the water in said hole’ effectively overturning 100+ years of western water law and numerous legal opinions regarding ‘permit exempt domestic wells’. The decision was ‘to protect minimum stream inflows and senior water rights’-really a way to grab more money from the citizenry.
Legislators ‘fixed’ the resulting chaos a year later. The ‘fix’ entails you paying the state and county more money for less water out of the well.
