Restoring a Large Natural Spring-Fed Pond

Owner of a large, stone-lined fresh/saltwater pond near the ocean wants to remove muck, unclog springs, and restock. Asks about dredging, activated charcoal, and suitable fish/plants.

Restoration Steps

1. Dredge simultaneously—rent equipment that removes water and sediment together.
2. Test water after cleaning for salinity, pH, and contaminants.
3. Stock appropriately—choose species matching the salinity regime (e.g., sheepshead minnows, mollies, or salt-tolerant natives).
4. Plant natives—spartina, pickleweed, or other salt-marsh vegetation.

Activated charcoal won't fix ongoing spring contamination. Address the source first. Professional help may be needed for large-scale dredging.
