Aqua Sierra, inc.

Aqua Sierra, Inc., based in Colorado with over 30 years of experience, is a fisheries management and water quality consulting firm staffed exclusively by degreed biologists, geologists, and engineers, serving clients in Colorado, New Mexico, Arizona, and internationally. The company designs and installs custom-engineered bottom-diffused aeration systems featuring fine-bubble technology with independently certified approximately 3% oxygen transfer per foot of water depth per ASCE standards, claiming one-sixth the energy cost of surface aerators, no sludge removal for 20 years, no odor, and a single moving part with 30% oxygen transfer at 10-foot depth. Their Aerated-Facultative Lagoon systems use fine-bubble bottom-laid aeration with a 5-year manufacturer guarantee for target BOD and TSS levels. Each aeration system is site-specifically engineered for water body size, depth, shape, temperature, and species, with dual compressor redundancy and warranties including lifetime coverage on aeration tubing, 5 years on aeration modules, and 1 year on the overall system. Additional treatment offerings include ozone-enhanced aeration, copper ion treatment systems, and beneficial bacteria injections. Beyond aeration, Aqua Sierra provides comprehensive fisheries management including professional fish stocking with less than 1% mortality, trophy fishery development, fish population surveys, invasive species removal, and full laboratory water chemistry analysis covering 23-plus parameters. The company also offers lake, stream, and pond design services with bathymetry and GIS mapping, and is a licensed herbicide applicator for aquatic vegetation and algae control. Notable clients include the Smithsonian Institution, with projects spanning from Colorado to Russia, China, South America, and Africa.
