A backyard pond adds a completely different dimension to a Pittsburgh yard. The sound of moving water, the texture of aquatic plants, visiting wildlife — it's one of the most rewarding landscaping projects you can take on.
Pittsburgh's climate (USDA Zone 6b) and abundant rainfall actually make it a good region for backyard ponds, as long as you plan for the winters.
Types of Backyard Ponds
Preformed pond. A rigid plastic or fiberglass shell you bury in the ground. Cheapest and fastest to install. Limited shapes and sizes, but a good starting point for a small water feature.
Liner pond. A flexible rubber liner (EPDM or PVC) laid over a dug-out shape. Allows custom shapes and sizes. The most popular choice for residential ponds.
Concrete pond. Permanent, durable, and expensive. Best for larger or formal installations. Requires professional construction.
Container pond. A large pot, half-barrel, or stock tank placed on a patio or deck with a few aquatic plants and a small pump. No digging required. Great for small spaces.
Cost Breakdown
Pond costs vary widely based on size and complexity:
- Container pond (DIY): $50–$200
- Small preformed pond (DIY): $200–$800
- Medium liner pond (DIY, 6x8 ft): $500–$1,500
- Professional install, small-medium: $1,500–$5,000
- Professional install with waterfall: $3,000–$8,000
- Large custom pond: $8,000–$15,000+
Ongoing costs include electricity for the pump ($5–$15/month), fish food if you add fish, and seasonal maintenance supplies.
Best Pond Plants for Pittsburgh
Pittsburgh's freeze-thaw winters mean you need plants that can go dormant and come back reliably. These all work well in Zone 6b:
Aquatic plants (in the water):
- Hardy water lilies — the classic pond plant, overwinters at the bottom of the pond
- Pickerelweed — blue flower spikes, thrives in shallow water
- Water hyacinth — floating plant, treats as annual in Pittsburgh (won't survive winter)
- Hornwort — submerged oxygenator, helps keep water clear
Marginal plants (pond edges):
- Blue flag iris — native to Pennsylvania, beautiful purple blooms
- Marsh marigold — bright yellow spring flowers, loves wet feet
- Cardinal flower — red spikes, attracts hummingbirds
- Japanese iris — elegant, handles Pittsburgh winters well
Surrounding plantings:
- Ferns — natural look along pond edges
- Hostas — shade-tolerant, lush foliage
- Ornamental grasses — add movement and texture
- Astilbe — feathery plumes, thrives in moist soil
Pittsburgh-Specific Considerations
Winter care. Ponds deeper than 18–24 inches generally don't freeze solid in Pittsburgh. If you have fish, keep a small area of the surface ice-free with a pond de-icer or aerator so gases can exchange. Move the pump to shallow water in winter so it doesn't circulate the coldest bottom water.
Slope and drainage. Many Pittsburgh yards slope, which can actually work in your favor — a natural grade makes it easier to create a waterfall or stream feature. Just make sure runoff from the yard doesn't wash soil and debris into the pond.
Clay soil. Pittsburgh's clay-heavy soil holds water well, which means your pond liner won't dry out easily. But it also means digging is harder — consider renting a mini excavator for anything larger than a small preformed pond.
Mosquitoes. Not a problem if you have moving water (a pump or fountain) or fish. Goldfish and mosquito fish eat larvae aggressively. A stagnant, unpumped pond will attract mosquitoes — avoid that.
DIY Supplies
If you're building your own:
- Pond liner EPDM — flexible rubber liner for custom shapes
- Pond pump — keeps water moving and prevents stagnation
- Pond filter — keeps water clear, especially if adding fish
- Pond de-icer — keeps a hole in the ice during Pittsburgh winters
- Aquatic plant baskets — contain plants while allowing root growth
- Pond water test kit — monitor water quality
