Pond builders, water feature care and lake management across Orange County
Koi Pros is based in Orange, so Orange County is home turf. Our crews run routed maintenance through north, central and south county every week, and construction and repair crews are usually on-site within days. Coastal humidity, inland heat and Santa Ana winds each change how a pond behaves, and we've serviced ponds in every part of the county for four decades.
What shapes pond and water feature work in Orange County
Fill water
Most of the county drinks a blend of Orange County groundwater basin wells and imported Metropolitan water, moderately hard and chloraminated; a few cities (Costa Mesa, Villa Park) run on local sources with their own quirks. Recycled water irrigates most HOA common areas and must stay out of ponds and lakes.
Heat, wind and evaporation
Marine on the coast (70s), inland-valley heat in north and east county (low-to-mid 90s), and Santa Ana wind events every fall that load skimmers overnight and spike evaporation. Frost is rare outside the canyons.
Predators and wildlife
Great blue herons, night herons and egrets commute from Upper Newport Bay, Bolsa Chica, Irvine Lake and the county's dozens of HOA lakes; raccoons are the top residential koi loss in every city; coyotes and bobcats patrol the foothill and canyon edges.

Customer story
Victoria's raised koi pond in Garden Grove
“My son found Wes with Koi Pros online, and Wes built this above-ground fish pond for me. It's come out very nice. Every day my husband will come out here and relax and sit by the pond and enjoy the sounds and beauty of the Japanese-style koi pond Wes built for us. We also use it to water our plants with the fish waste, and our plants are very beautiful because of that. We are very pleased with Wes and his team.”
Victoria, homeowner for 30 years, Garden Grove, CA
Victoria has lived in her Garden Grove home for 30 years. Her son found Koi Pros online, and Wes built a raised, Japanese-style koi pond with a waterfall for her backyard. Her husband sits by it every day, friends come over to see it, and the fish water feeds the garden.
