About Salt Lake Dam
The primary purpose of Salt Lake Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Robert Anderson (private). It impounds the S Fork Grand River-tr.
The dam stands 11 feet tall and stretches 520 feet across, creates a reservoir covering 14 acres, has a maximum storage capacity of 109 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1954, the structure is well into its service life at over 50 years old.
