Water Rights

The Town of Castle Valley owns four large water rights which it holds for the long-term development of the Town. The priority of the Town's water rights date from the 1960's.  

Through the issuance of Water Permit Agreements, property owners can be assigned portions of the Town's water rights so that they can drill wells and use water for their households, for irrigation and for livestock.  Water Permit Agreements do not create a separate water right for an individual lot or for a property owner.   They allow the lot owner to use a specified amount of water on the lot under a Town water right.   Owners can request changes in allocated amount as activities on the lot change.  Also, the allocated amount registered with the Town passes with the land as lot ownership changes.

The Town believes that with proper management there should be sufficient water rights for the development of all the platted lots in the Town, and that is our goal in managing our water rights.   However, the Town cannot absolutely assure property owners that that will be the case over the long run.   

As a result of state legislative changes in 2008, by holding water rights for the development of the Town, the Town is acting as a "public water supplier" even though the property owners must drill their own wells.   As a "public water supplier" the Town must be diligent in assigning and tracking the use of its water rights.  In 2009, the Town Council worked on the procedures the Town will follow as a result of the new legislation in order to assure the most effective management of these rights.  It completed this work in the winter of 2009.

Property owners who seek to drill wells and start development of their property may sign an Water Permit Agreement with the Town in order to receive a start card from the State.   Property owners who wish to sign an Water Permit Agreement or who have questions should contact Mayor Dave Erley.

Watershed Protection

Thebof the Town of Castle Valley states the following to be our Goal with regard to water: To maintain or enhance water quality and quantity in the Castle Valley watershed by improving our knowledge, developing policies, and taking action as needed.

The source of well water for Town residents, depending on location, is either the valley-fill aquifer or, for those who live closer to Porcupine Rim, the Cutler formation aquifer. The latter tends to have significantly more solids and salts in it, and it impacts the quality of valley-fill aquifer in the lower part of the Valley.

The quality of the water varies in different parts of the Town. The Utah Division of Water Quality has officially classified the water quality based on a classification system focused primarily on total dissolved solids (see Water Classification Map).

The Valley-fill aquifer is fed from a large watershed in the La Sal Mountains whose boundaries were defined by the Federal Environmental Protection Agency in 2001 (see Watershed Map) when it declared the watershed to be a sole source aquifer. This means that the aquifer system is the sole and principle source of drinking water for the residents of the Town and that contamination of this aquifer system would be detrimental to the health and safety of the town residents.

In 1996, the Town passed a Watershed Protection Ordinance. The Town is committed to working with private landowners, agencies and authorities that own property in the Town's watershed to protect water quality and quantity. The Town also tries to use the EPA sole source aquifer designation as much as possible in these interactions.

At this point, there are no good firm estimates of the Valley's overall water capacity, i.e. size of aquifer, quantity of recharge, amount of usage. The Town now has six monitoring wells for measuring water quality changes over time. Obvious potential hazards include: herbicides/ pesticides, septic discharge, poor agriculture and livestock practices, organic chemicals from fuel storage/cars, etc. In the Town General Plan, there is a commitment to address potential hazards by using education, incentives and/or regulation.

A number of publications regarding what we know and don't know about our watershed and its process are gathered in the Town Building and are available to the public.

In 2006, Alice Drogin formed a Watershed Protection Group, which is the latest in a series of groups and task forces which have looked into how to best protect the quality and availability of Castle Valley's water. This group is working on a draft Water Protection Plan to strengthen and add to elements of the Watershed Protection Ordinance passed in 1996.


Water Quality Data

These results are test site specific and are used to gain a general understanding of changes in, and trends of the water in Castle Valley.

These results may not be representative of any individual well. To determine if your water is within drinking water standards you should have your water tested by a testing service.

General information on drinking water standards is available from the EPA.
