Completed in 1968, this 29-foot high structure serves the primary purpose of flood risk reduction and has a storage capacity of 1,005 acre-feet with a normal storage level of 98 acre-feet. The dam has a controlled spillway and is equipped with one valve outlet gate.
Despite its low hazard potential, the SCS-Upper Clear Boggy Creek Site-50 poses a very high risk due to its location and design characteristics. The dam has not been rated for its condition, and the last inspection was conducted in 1980 with an inspection frequency of every 5 years. While it meets state permitting, inspection, and enforcement requirements, there is limited information available on emergency action plans, risk management measures, and inundation maps for this structure. Given its critical role in flood risk reduction, ongoing monitoring and maintenance are crucial to ensuring the safety and effectiveness of this dam.
