Eli and LakeTech have been amazing to work with. They advised what chemicals would work best for my pond and even after the sale spent 40 minutes on the phone with me telling me how and when to use them. Pricing and product are amazing and the customer service is even better. Will be ordering from them again. 6 out of 5 stars!!!

LakeTech are a great company and have gone above and beyond to provide support while we were under staffed. Eli and his team were very responsive to concerns about the water quality and come onsite to take readings as well as applying product to help with the algae growth. They were able to look at the diffuser system that was in place and needed to be upgraded. Eli as always went above a beyond in assisting with the removal and installation of the new diffuser system. Eli and his team are easy to work with and responsive to the water quality needs.

LakeTech has been wonderful to work with as our community's lake management consultant. We love that LakeTech is modern - they use real-time buoys for monitoring lake health and have an online lake platform to track historical data, log field notes, and observe trends for our lake.

We have worked primarily with Eli Kersh - President of LakeTech. He is very knowledgeable. He explains our lake's ecosystem and behaviors in a way that all of our residents can understand. He truly cares about doing things the right way while also helping us find cost effective approaches to every decision we make. It has been a great partnership so far and we look forward to continuing work with Eli and LakeTech!

I truly believe that Eli Kersh and LakeTech are the best lake management and consulting firm in the world. When I first met Eli, our poor little Peacock Gap Lagoon was an aging, large, shallow, sediment filled lagoon with depressingly low levels of oxygen, more conducive to supporting plant life than aquatic life. Eli rolled up his sleeves and performed a detailed analysis of our lagoon, which included everything from water quality sampling, extensive mapping (both depth soundings and plant volumes), as well as the study of the existing plant life. He ultimately developed a Lake Management Plan which provided our roadmap to rehabilitation. Eli has been intimately involved every step of the way, his support has been unwavering, and his passion for lake management keeps us motivated during the inevitable ups and downs that are bound to occur. Fast forward to today and I am proud to report that thanks to Eli and LakeTech, we have dramatically increased oxygen levels, decreased sediment levels, and by extension have virtually eliminated algae blooms. We have also implemented the LakeTech real-time monitoring solution which has been an absolute game changer. Now in real time we can monitor everything from our oxygen levels, to the water temperature, to the impact that weather, and more specifically rain, have on our water body. I literally log onto the client portal every morning over my cup of coffee to see how things are doing. I can point to one particular incident during the 2021 heat wave where I noticed that oxygen levels had decreased dramatically in 24 hours resulting in a potential fish kill. Fortunately, having access to the real time information, we were able to perform an emergency water circulation event with the Bay and averted the near disaster, LakeTech literally saved lives that day! I honestly believe that Eli and LakeTech were the Lake Fairy's gift to the Peacock Gap Lagoon, I have no idea what we would have done without him, and cannot recommend both he and LakeTech strongly enough.

Eli is considered yoda among the lake management crowd. He is our guide, teacher and friend in the industry.

If you are lucky enough to be able to even hire him your lake and future generations will thank you. Your lake will be happy and healthy for years to come.

Eli at LakeTech has provided PCA services for me over the past 2 years, assisting me with the diagnosis and treatment plan for a large property in Santa Cruz County dealing with invasive vegetation.
I highly recommend LakeTech for vegetation management and invasive weed consulting.
