This dam was inspected on 8 November 1979 by Anderson-Nichols Co., Inc., under contract to the State of New Jersey. The State, under agreement with the U.S. Army Engineer District, Philadelphia, had this inspection performed in accordance with the National Dam Inspection Act, Public Law 92-367. Subsequent inspection of Sunset Lake Dam on 31 January 1980 by Corps and State personnel revealed the dam to be in an UNSAFE, non-emergency condition. This condition, seepage and wet, soft areas on the downstream toe of the dam, if left uncorrected, could result in failure of the dam resulting in possible loss of life and property damage. Until further study can determine the full extend of the problem and possible permanent remedial action, temporary measures were recommended to preclude serious property damage and possible loss of life. The District Engineer notified the Governor's representative by telegram of the UNSAFE condition on 1 February 1980 (Copy attacted to this assessment) (Also, an 'UNSAFE DAM' data sheet was submitted to the U.S. Army Engineer Division, North Atlantic on 4 February 1980. A copy of this sheet is attached). Meanwhile, the State notified of owner by letter of the recommendations. The owner has lowered the level of the lake as recommended.
