About Pine Hollow
The primary purpose of Pine Hollow is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Badger Improvement District (local government). It impounds the Badger Creek & Pine Hollow Creek near Tygh Valley.
The dam stands 66 feet tall and stretches 800 feet across, creates a reservoir covering 235 acres, has a maximum storage capacity of 5,300 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1969, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam.
