This earth dam stands at a height of 27 feet, with a structural height of 32 feet and a length of 395 feet. With a storage capacity of 94.8 acre-feet and a drainage area of 128 square miles, this dam plays a crucial role in protecting the surrounding community from potential flooding events.
The dam features an uncontrolled spillway with a width of 30 feet and a hazard potential rated as low. Despite being labeled as not rated in terms of condition assessment, the dam has undergone regular inspections with the last one conducted in May 2005. With a moderate risk assessment score of 3, efforts for risk management measures and emergency action plans are yet to be fully developed. Grassy Creek Watershed Dam G-79 stands as a testament to the importance of sustainable water resource management in mitigating flood risks and ensuring the safety of local communities in the face of climate variability.
