Office of State Engineers (OSE) Deep Piezometers

Science Center Objects

In 1996, the U.S. Geological Survey, in cooperation with the New Mexico Office of the State Engineer (OSE), began a drilling program to install specialized monitoring wells in the Middle Rio Grande Basin and the Espanola Basin.


The purpose of the program is to monitor hydraulic head at specific depths in the aquifer. Most of these specialized wells, called piezometers, are located in areas between major water-production wells, so that data collected are more representative of general conditions in the aquifer than of conditions influenced primarily by the daily on-and-off cycles of the production wells.



  • Collect continuous water-level data from data loggers at 12 sites with 31 piezometers every two months.
  • Maintain collected data in USGS databases.
  • Make all data available on line.



Provide OSE with continuous water-level data from piezometers nests at the Lincoln Middle School, Matheson Park, Mesa del Sol, Dome Road, Nancy Lopez, Tome, Bernalillo, Phoenix Road, Archery Range, OSE  County, Fairgrounds, Jail and Cuyamungue sites. Activities to achieve this objective include operation and maintenance of water-level data collection equipment; retrieval, quality assurance, and entry of water-level data into the ADAPS and GWSI database; and provision of electronic access to data by the OSE via the web.
