Revises provisions relating to water. (BDR 48-886)

AB 190 creates a new "Fund for Hydrological Studies" to change how costs are shared for required water-related studies in Nevada counties with under 100,000 residents (all counties except Clark and Washoe). It requires applicants to pay 50% of the study cost upfront, with the state covering the remaining 50% using funds from this new account. If the fund lacks sufficient money, the state uses an existing "Account for Studies Concerning Water" to cover the balance, and applicants can either pay the remaining cost or withdraw their application for a refund. This shifts the financial burden from applicants covering 100% of costs under current law to a shared 50-50 model.
