Water quality adversely affects electrofishing survey catch rates – if your using inadequate electrofishing equipment. West Texas and Oklahoma water is high conductivity water. East of I-35 in East Texas, water conductivity falls rapidly. It’s due to high TDS (total dissolved salts) in the west region and low TDS in the east region. Electrical conductivity
Humminbird and Lowrance have recently tried to join the custom lake mapping business in the last 18 months – creating custom bathymetry and bottom hardness maps while you travel through the water collecting data. Although the aesthetics of their maps are enticing, the data behind the pretty-looking maps is lacking for professional purposes. Two main

Our drones are extremely useful for analyzing vegetation densities for planning purposes, quoting the project and determining project success. Here’s an example of a lake that was inundated with floating algae, coontail and bushy pondweed. The client wanted quick results without harming the fish, so we opted to use the Truxor to perform triage to

Infrared sensors on our drones help us detect and assess aquatic vegetation infestations in ponds and lakes. Here’s a survey we completed today to gather data before removing aquatic vegetation. A post removal survey will be done to show the completed project results to the client as well as continue to monitor future growth for
There are many factors that cause ponds to fill with silt and sediment – storm water runoff carrying soil is one of the most common. The question is, how much sediment is your pond or lake collecting? Where is it collecting? At what rate is it collecting? How much original capacity is left? When will
