Building a Garden Pond: Planning, Depth & Location

A garden pond is a rewarding weekend project that often becomes a lasting passion. Planning prevents the #1 regret: building too small.

Koi vs. Goldfish Ponds

Koi: Need space and depth. Minimum 1,000 gallons, 4–5 ft deep zone. Large, long-lived fish.

Goldfish: Smaller, shallower OK. Mild winters: 2 ft depth. Cold winters: 16+ inches to prevent solid freeze.

Site Selection

Away from Trees: Leaf litter = constant maintenance.

No Runoff: Fertilizers, chemicals contaminate water.

Sunny Spot: Attracts wildlife, supports aquatic plants that balance ecology.

Plan for the mature vision, not just the starter pond.
