Servicing farm and agricultural water features to community lakes — including HOAs, apartment complexes, and more. Our services range from custom lake maintenance to complete equipment overhauls. Oftentimes, we’ll service multiple types of water features on one property and offer pond maintenance services when needed.


Offering custom service options for commercial and koi pond maintenance and water gardens. Understanding key elements in a koi pond or lake is a must in order for a healthy ecosystem to thrive and create beauty for your landscape. Offering custom landscape design is a service we also provide, in addition to introduction of native plants and other aquatic management services. LMI has partnerships with some of Southern California’s premier aquatic plant suppliers. You can visit them with water samples to determine which fountain, pond or lake aquatic plant culture you need before installation.


From floating blue-green algae to harmful algae blooms, we have most likely handled it before, or are still currently handling it. Certain types of algae and aquatic weed are difficult to remove. They recede in the colder months / during the winter, and then they break out in full bloom come spring and summertime. For this, we’ve created a “summer-time maintenance plan” and “winter-time maintenance plan” for our clients. The last thing any commercial property wants to do is leave their lake untreated for nuisance vegetation removal during the colder months. Your warmer months could then turn costly when you don’t manage your pond or lake.


With every water feature, comes aquatic pond equipment — from filtration, pumps and UV lights to custom resealing, aeration additional, and more. Our technicians will know what is best for your water features when reviewing your property. We work with commercial contractors when our clients need pump vaults installed, and large pond and irrigation pumps repaired or replaced, in addition to large custom bio-filtration installation and cleaning.

Fish Stocking & Fisheries Management Services

Lake Management Inc. is the leading lake and pond fish stocking source in California and Arizona. Our experienced staff has been helping public and private lake owners with fish stocking programs for well over 40 years. The maintenance support and service we provide, including restocking, is what sets us apart.

Shoreline Restoration & Erosion Control

It should never be overlooked. It is one of the most important aspects of a healthy lake or pond. Proactive buffer and littoral zone management not only helps increase the aesthetics of your lake or pond, but it helps protect your waterbody from the harsh effects of erosion and prevents excess nutrients from entering the water column. If erosion damage has become too severe, erosion repair solutions can be implemented to help restore the shoreline and prevent future damage.

Let’s face it, managing large bodies of water is work! Fortunately, we can help. We specialize in the management of large bodies of water. From equipment to water chemistry and more — Lake Management Inc. is here to help.

Increasing your filtration size can help cover more waste when your system is overpopulated.

Changing your pump from a submersible pump to an external pool pump helps move more water.

Adding an ultraviolet light to your water feature helps improve clarity, kills bacteria, and provides algae control.

Adding larger returns and on either side of your water feature helps heavy sediment make it to the filter.

Feeding your fish and wildlife less helps reduce waste and is therefore less work for your equipment to handle.

Having annual or semi-annual cleanings will help remove excess waste and vegetation that don’t reach the equipment.
