Water loss around the edges of a waterfall is often caused by low liner edges, splashing water, or rocks and debris redirecting water outside the waterfall. Inspecting the waterfall while it is running can help identify where water is escaping.
How to check for water loss
- Inspect the waterfall edges. Look for wet soil, mulch, gravel, or muddy areas along both sides of the waterfall and stream.
- Check for low liner edges. Soil beneath the liner can settle over time, allowing water to flow over the edge of the liner and into the surrounding ground.
- Look for splashing water. Watch where water flows over rocks and waterfall drops. Water may be splashing beyond the liner instead of returning to the pond or reservoir.
- Check for obstructions. Rocks, leaves, algae, and excessive plant growth can redirect water toward the edges of the waterfall.
- Follow the water flow. Observe the entire waterfall, starting at the top and working downward, to identify areas where water may be escaping.
How to correct water loss around the edges
- Low liner edges: Carefully lift the liner and add compacted soil underneath to raise the edge and keep water contained.
- Excessive splashing: Reposition waterfall rocks to direct water back into the waterfall or stream.
- Obstructed water flow: Remove debris and trim excessive plant or algae growth to restore proper circulation.
After making adjustments, run the waterfall and inspect the surrounding areas for continued water loss.
Important: Some water loss from evaporation and splashing is normal. However, excessive or frequent water loss may indicate a leak that requires additional inspection.
