The legal framework for the administration of water appropriations in Colorado is known as the prior appropriation doctrine. This doctrine establishes a priority system for water allocation in time, place and amount and thereby regulates the use of water. This system is mandated by Colorado’s Constitution and is also referred to as the “prior appropriation doctrine.” Colorado is perhaps the most stringent of all western states in terms of adherence to the prior appropriation doctrine.
The water appropriation system is based upon the principle of “first in time, first in right.” Water users with the oldest, or “senior,” water rights must be fulfilled before junior water rights can divert. This can result in the curtailment of junior water rights in times of short supply.
