Construction Foundation Report for Seepage Control Adits Abiquiu Dam andReservoir, New Mexico

摘要

Abiquiu Dam was completed in February 1963. The spillway was modified and theembankment was raised in 1986. The project now consists of a 1,800-foot-long, 340-foot-high rolled earth filled dam with a 68-foot wide uncontrolled spillway located 4,000 feet north of the left abutment. Seepage through the abutments has been a problem since shortly after project completion. Supplemental grouting programs in 1966, 1978, and 1980; and drainholes drilled in 1966, 1977, 1979, and 1980 failed to provide adequate control of seepage. The adits were constructed to capture and provide controlled drainage of this seepage.
