Directly below the county's flood-control reservoir
Mount Holly's location on the Catawba River goes back to Catawba Nation settlement and 1770s European arrival, with John L. Tate's 1848 Mountain Island Mill the first river-powered mill on the site and the Mount Holly Cotton Mill following in 1875. That river-falls location is also why Mount Holly sits immediately downstream of what is now Mountain Island Lake.
What sitting below the reservoir means for storm response
During Hurricane Helene in September 2024, Mountain Island Lake rose roughly 10 feet above its normal maximum level, reaching its sixth-highest recorded level at the dam, and evacuations were ordered along the Catawba in both Gaston and neighboring Mecklenburg counties as floodwater affected roughly 170 homes in the floodplain. A Mount Holly property's exact elevation and distance from the river matter more here than almost anywhere else in the county, given the town's position just below that reservoir.

What to include in your message
Share the water source, how long it's been present, affected rooms and materials, the home's age if known, and access conditions. Confirm licensing and insurance directly, since provider availability shifts fast after a regional flood event.
Reservoir and flood-history context
Mountain Island Lake's normal elevation runs around 96 feet with a maximum of 100 feet; Helene pushed water roughly 10 feet past that ceiling in 2024, a scale of rise worth understanding for any Mount Holly property near the river.
