Koi Pros

Pond, lake and water feature contractors for Riverside and San Bernardino counties

Inland ponds live a harder life: 100°F summers, hard water, and wind. We build deeper, filter bigger and aerate more here than on the coast, and we run weekly commercial routes through Riverside, Corona and the Temecula Valley.

    What shapes pond and water feature work in Inland Empire

    Fill water

    Mostly local groundwater in Riverside and Redlands, blends elsewhere; hard, high-alkalinity water that buffers pH well but scales pumps, UV sleeves and nozzles. Some cities use free chlorine rather than chloramine, so we test before every refill.

    Heat, wind and evaporation

    Upper 90s to 100°F+ summers, cold clear winter nights with frost, and the region's signature Santa Ana winds through Cajon Pass and the Santa Ana Canyon. Depth, shade, aeration and windbreaks are standard here.

    Predators and wildlife

    Coyotes, bobcats and the occasional mountain lion on foothill and plateau properties; herons and pelicans from Lake Elsinore, Canyon Lake, the Santa Ana River and the golf lakes; javelina do not reach this far west.
