Abstract
Painted Rock Dam, a 181 ft (55.2 m) high, zoned earth embankment detention structure near Gila Bend, Arizona, retained approximately 2.3 million acre ft (2.8 x 109m3) of water for an extended period during the winter of 1978- 1979. Several areas of seepage developed over major portions of the downstream valley and in a minor area on the right abutment. These areas were monitored while instrumentation was installed and investigations made to determine the nature of the seepage and provide the basis for evaluation of structural performance and design of necessary relief and control measures. Construction of seepage relief and control measures and stabilizing berms was accomplished in the fall of 1979. Performance of the project has been evaluated during subsequent storage periods through 1986, with the conclusion that the control measures are functioning satisfactorily, and in general accordance with design concepts. Site conditions, original design and construction, seepage observations, instrumentation, investigations, evaluations, and design and construction of remedial measures are summarized and lessons learned are presented.

Underseepage Control Measures at Painted Rock Dam
Painted Rock Dam, a 181 ft (55.2 m) high, zoned earth embankment detention structure near Gila Bend, Arizona, retained approximately 2.3 million acre ft (2.8 x 109m3) of water for an extended period during the winter of 1978- 1979. Several areas of seepage developed over major portions of the downstream valley and in a minor area on the right abutment. These areas were monitored while instrumentation was installed and investigations made to determine the nature of the seepage and provide the basis for evaluation of structural performance and design of necessary relief and control measures. Construction of seepage relief and control measures and stabilizing berms was accomplished in the fall of 1979. Performance of the project has been evaluated during subsequent storage periods through 1986, with the conclusion that the control measures are functioning satisfactorily, and in general accordance with design concepts. Site conditions, original design and construction, seepage observations, instrumentation, investigations, evaluations, and design and construction of remedial measures are summarized and lessons learned are presented.
