Due to upstream pollution from a shooting range owned by Highland Ventures, LLC, Blue Hole Creek is now listed as impaired.
MWA's testing has shown lead levels in the creek as high as 400 parts per billion. The water has also been acidic.
Blue Hole Creek was at one time an Exceptional Value waterway. The creek was a reliable source of drinking water for backpackers on the Laurel Highlands Hiking Trail.
Further downstream, it provided plentiful wild trout for anglers.
The actual “Blue Hole” is a deep, rock-lined swimming hole where locals and visitors alike would go to escape the summer heat.
This once-pristine stream is now contaminated with lead and other heavy metals.
The Association said the Department of Environmental Protection has not taken action to hold the shooting range owner Highland Ventures, LLC accountable for the contamination.
The Mountain Watershed Association reported lead and heavy metal contamination in Blue Hole Creek in April 2025. Read more here.
In July 2025, Highlands Ventures received a notice of violation for failing to comply with federally outlined Shooting Range Stewardship Best Management Practices. Read more here.
MWA wasn’t the first to report issues in the creek. DEP received complaints about impacts caused from Highlands Sporting Clays, the prior owner, as early as 2021, and water quality testing showed contamination in 2023. Read more here.
