Just because the water lies under your property, does not mean you automatically own it.
Dutch here is an expert on this issue. as he uses lots of spring water for his operations, and has dealt with varying flow rates.
It has been in the news over the last few years, that the aquifer in the Magic Valley Idaho has been dropping, as large ag producers punch wells for irrigation. But the water rights to those wells are in many cases junior to the guys depending on spring flows where the aquifer resurfaces.
When the guy with senior water rights starts losing his flow. The guy with junior water rights loses his water first.
