What this page is, and is not
Every line and point here is a feature the Office of the State Engineer publishes, placed inside this region by its own geometry — nothing is drawn or assigned by hand. The state maps 111 ditches here and names 10 of them. That is a count of what one dataset records, not a count of how many acequias run in this valley — the OSE's named-acequia layer covers some regions richly and others barely at all. Where this page is thin, the valley is not.

Mora County: two acequias are fighting a state cut to their irrigation water

Las Acequias de Cañoncito y Encinal say the Office of the State Engineer ordered their headgate closed and set a valley-wide water allowance well below what their own hydrologist found the land needs.

Live from the USGS National Water Information System. Cubic feet per second — one cfs is about 449 gallons a minute. A tile that says no reading means the gage did not report, which is not the same as a dry ditch.

What this desk covers

An acequia is a community-governed irrigation ditch. In New Mexico it is also a political subdivision of the state, with elected commissioners and a mayordomo, and many of them are older than the state, the territory, and the counties drawn around them. Their business happens at the ditch, at the county, and at the Office of the State Engineer — almost never at a city council, which is why the rest of this site cannot carry it.

Office of the State Engineer (OSE)
The state agency that administers New Mexico's water rights, issues permits, and enforces compliance orders.
Adjudication
The court process that decides, for every user on a stream system, how much water they have a right to and how old that right is. Seniority decides who gets water in a dry year.
Consumptive Irrigation Requirement (CIR)
The state's estimate of how much water a crop actually consumes on an acre in a given place, in acre-feet per year. In an adjudication it becomes the ceiling on a water right — so the number itself is often what the fight is about.
Headgate
The gate where a ditch takes water from the river. Ordering one closed stops the whole ditch.
