Additionally, my family are veterans of the California water wars, railroad wars, and claim jumping days, and I can take you on tour of central California graveyards, and point out the graves of several citizens that thought all the water was theirs. Interestingly, most were not put there by government agents, but by their neighbors during the period of time that water rights law was being formed.
Keep in mind that flooding and flood control policy and law was also formed during this period using a similar rights/responsibility balance.
Your personal opinion on private property water rights is worthless unless you are King, and certainly not evidence that my statement is inaccurate in any way.
You can go back to snuggling with big brother. I agreed that some cases would be more complex than others, but at least they ought to be able to store some of the rainfal on their own property to use later.
But if you like big brother telling you the water that falls on your land, you can’t touch it without their permission, then more power to you. It’s good to admit who you really are.
