Completed in 1937, this earth dam spans a length of 7260 feet and reaches a height of 8 feet, providing crucial storage of up to 384 acre-feet of water for various purposes. Situated on Grays Creek-Offstream, the dam's controlled spillway with a width of 92 feet ensures efficient water discharge during peak flows, contributing to flood control efforts in the region.
Despite its significance, the H-1 Pool Dam exhibits signs of wear and tear, with a poor condition assessment noted during the last inspection in July 2018. Recognized as having a low hazard potential but a very high risk level, the dam requires attention to ensure its long-term safety and functionality. With the Michigan Department of Environment, Great Lakes, and Energy overseeing state regulatory aspects, ongoing inspections and risk management measures are crucial to safeguarding this critical infrastructure and the surrounding community.
As a key component of water resource management in Schoolcraft County, the H-1 Pool Dam serves as a reminder of the importance of proactive maintenance and risk assessment in maintaining the integrity of our water infrastructure. With its historical significance and essential role in flood control, efforts to address its condition and mitigate risks are essential for ensuring the continued protection of downstream communities and the environment.
