Many of these records are referenced to one of our one hundred eighty nine (189) MRGCD property maps that span from Cochiti Pueblo and Reservoir to San Marcial, north of Elephant Butte in central New Mexico.

Each MRGCD Property Map typically illustrates two square miles of real property records. These maps have been drawn and updated to reflect current property records since 1927 by MRGCD mapping staff.  Staff works closely with the county Clerks and Assessors that overlap with MRGCD.  Early MRGCD property maps are some of the first cadastre maps drawn in New Mexico that describe real property within Land Grant boundaries in New Mexico.

This map collection and repository for real property records has tracked all real property changes within the MRGCD jurisdiction in order to protect MRGCD rights-of-way and provide for drainage, irrigation and flood control in the Middle Rio Grande valley.  The department houses many of the plats, surveys and deeds used to locate and reference these properties.

Much of the property in the valley was unplatted at the time the MRGCD was formed. In order to appraise the properties, these lands were given unique legal descriptions. A Property Map and tract number was then associated to each unplatted parcel. These MRGCD Map and Tract designations are still found throughout the valley as a part of the legal descriptions on current plats and deeds.

The Mapping and GIS Department maintains specific information on all of its facility rights-of-way, including Plan and Profile (P&P) sheets, easement records, rehab drawings, tax dockets and deeds. Other current and historic documents are available as well.

GIS (Geographic Information System) Staff are responsible for the preservation and continuation of Mapping and GIS Department records. Since 2000, the MRGCD property maps have been maintained as a Cadastral layer using Esri ArcGIS software. Staff statutorily collaborates with the offices of the County Clerk and the County Assessor in each of the four counties that fall within the jurisdiction of the District in order to access the most current property and ownership information. Links to these counties are here:


Sandoval County


Bernalillo County


Valencia County


Socorro County

The MRGCD relies on these connections to the county Clerk and Assessor offices for access to current real property records such as filing number, filing date, county parcel number (UPC), ownership, address and tax district designations.

The incorporation of GIS into the Mapping Department supports many District functions, including: maintaining historic and current irrigation records; mapping and analysis for MRGCD Division field operations; Engineering and Assessment Department support; and Qualified Elector lists for MRGCD elections

Online access and digital preservation of MRGCD maps and documents is an active area where staff uses GIS to inventory and provide a spatial component to MRGCD records.
