Dams play an integral role in the hydrological system of any region, especially in South Carolina with its impressive count of over 10,000 dams. These structures serve multiple purposes – from flood control and water supply to irrigation and electricity generation – thereby contributing significantly to the economic and social well-being of the communities they serve. However, with such a crucial role comes an immense responsibility for safety and structural integrity. Inspecting these dams regularly and particularly after high-water events is therefore of utmost importance. Routine inspections can detect signs of wear and tear, material degradation, or structural anomalies that could compromise the dam’s integrity, ensuring the safety of those living in downstream communities.
Given the vast number of dams in South Carolina, the task of inspecting them all is a considerable logistical challenge. Thankfully, The South Carolina State Guard (State Defense Force) has taken up the responsibility to assist with Dam inspections. The force has qualified engineers who have the skills and experience necessary to perform these vital missions and have been doing it for some time. These personnel are equipped with a wide range of inspection tools, from simple folding engineer rulers to sophisticated aerial drones, to access and evaluate even the most hard-to-reach locations. This innovative blend of traditional engineering methods and advanced technology maximizes inspection efficiency and minimizes the risk of oversight, thus ensuring that all possible deficiencies are identified.
The importance of dam inspections extends beyond the immediate safety considerations. Unaddressed structural deficiencies can lead to dam failure, a catastrophic event that can cause extensive loss of life and property in addition to environmental degradation. Additionally, the repair or replacement cost of a failed dam is significantly higher than the cost of routine maintenance and minor repairs identified through regular inspections. Furthermore, inspections also serve a critical function in ensuring the longevity and sustainability of these structures, contributing to the economic stability of the regions they serve. By investing in robust inspection practices, The South Carolina State Guard is not only safeguarding its citizens but also its environmental resources and economic prosperity.
South Carolina is filled with dams. There are over 10,000 locations throughout the state. About 34 of the 10,000 are federally regulated, while 2,317 are state regulated. S.C. State Guard personnel, including the SCSG-2BN-Highlanders and 1st Battalion underwent Dam inspection training with the SCSG Engineer Detachment, including use of imspection tools ranging from a simple folding enginneer ruler up to aerial drones for inspections in hard to reach locations. Dams needs to be inspected on a regular basis and after any high-water event. The purpose is to look for changes that may indicate the need for repairs or even the existence of serious deficiencies that if left unaddressed could lead to failure of the dam.
