Prior-appropriation water rights

Shortly afterward, Robert Phillips started a mining operation downstream and eventually tried to divert the water back to its original streambed.

[4] For water sources with many users, a government or quasi-government agency is usually charged with overseeing allocations.

The doctrine has historically excluded ecological purposes, such as maintaining a natural body of water and the wildlife that depends on it, but some jurisdictions now accept such claims.

Therefore, during times of drought, users with junior appropriation dates might not receive their full allocation or even any water at all.

[9] Withdrawal rights can be lost or shrunk over time if unused for a certain number of years, or if a litigant can demonstrate that the water's use is not beneficial.

[3][5] Abandonment of a water right is rare, but occurred in Colorado in a case involving the South Fork of San Isabel Creek in Saguache County.

[13][failed verification] Alaska, Arizona, California, Colorado, Hawaii, Idaho, Kansas, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, Wyoming all use the prior appropriation doctrine, with permitting and reporting as their regulatory system.

[12] Of these, California, Texas, and Oregon recognize a dual doctrine system that employs both riparian and prior appropriation rights (see § Interaction with other allocation methods).

Eight states (Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming) engage in prior appropriation without recognizing the riparian doctrine.

[14] However, prior appropriation does not always determine water allocation in these states because various federal regulations also have priority over senior users.

The question was not squarely presented again to the Colorado Court until 1882 when in the landmark case, Coffin v. Left Hand Ditch Co., 6 Colo. 443 (1882), the court explicitly adopted the appropriation doctrine and rejected the riparian doctrine, citing Colorado irrigation and mining practices and the nature of the climate.

You will be preventing those raindrops from entering the watershed, depriving people downstream from the surrounding creeks and rivers of their rights to use their apportioned amounts of streamflow.

But, in Utah and Washington (with the exception of Seattle), harvesting raindrops is still a crime.Even though water markets increasingly gain ground, many criticize the prior appropriation system for failing to adequately adjust to society's evolving values and needs.

[28] Environmentalists and recreational river-users demand more water be left in rivers and streams, but courts have been slow to accept these requests as beneficial uses.

The same first in time, first in right theory has been used in the United States to encourage and give a legal framework for other commercial activities.

Because appropriation theory in mineral lands and water rights developed in the same time and place, it is likely that they influenced one another.

The Homestead Act of 1862 granted legal title to the first farmer to put public land into agricultural production.
