Tijeras Canyon extends about 15 miles eastward from the eastern edge of Albuquerque, NM. The canyon is the site of a new part of Interstate Highway 40. The purpose of this report is to present surface- and ground-water data collected prior to and during highway construction. Well and spring data from near the construction site are tabulated, and spring inflow in Tijeras Creek is shown. Water levels in selected wells are shown in hydrographs based on monthly measurements and continuous water level measurements. This report includes all of the data in a similar previous report (U.S. Geological Survey Open-file report 78-238), plus approximately one additional year of data. (USGS).
