Daily Water Loss in a 3,000-Gallon Waterfall Pond: Normal Evaporation

Evaporation Math

A 5-ft waterfall in 80–90°F sun with 3,000 gallons can easily lose 1 inch/day (≈100–150 gallons). Wind increases it. No external moisture = likely not a leak.

Confirm with Bucket Test

1. Fill a bucket with pond water; mark level.
2. Place beside pond (same sun/wind).
3. Run waterfall 24 hrs.
4. Compare loss. If pond loses significantly more, you have a leak.

Auto-Fill Option

Rain barrel fed by downspout → float valve → pond saves tap water and effort.
