Why Lake Mapping?
We collect data with the high-tech, yet low-cost sonar/GPS hardware which keeps project costs low without sacrificing accuracy. The data will be used to calculate water volumes and other important lake measures of an entire body of water or a specific area you define. With standardized report formats, you will be able to quickly analyze data and view layered maps with bathymetric, vegetation and bottom hardness metrics. Additionally, each report has its own permanent web address, so you can easily access them from anywhere and share them with others.
We use a powerful cloud-based software to process and create reports and layered maps from this sonar data. These reports will allow you to establish a lake “baseline” so you can monitor changes in water volume, contour, sedimentation, and plant biomass. The resulting maps can be used to identify areas of concern, evaluate results of management activities, and develop data supported-recommendations to improve lake conditions over time.
We use a few maps to manage lakes:
- Bathymetric Map
- Bottom Hardness Map
- Submersed Aquatic Plant Map
This map depicts the submerged topography and physiographic features of ponds and lake bottoms to show detailed contours.
This map is valuable for lake managers because it provides adequate information on dissolved oxygen loss during the summer and the amount of plant material that inhabits the bottom of the lake. This allows lake managers to decide the correct application of herbicide treatments as well as harvesting activities and alum treatments.
Bottom Hardness Map
A bottom hardness map is created to help lake managers understand the material(s) at the bottom of a lake or pond. Hard bottoms consist of sand, gravel, and rock, which soft bottoms are muck and dense vegetative areas.
Ultimately, bottom hardness maps can help explain part of water clarity issues and overall health.
Lake Mapping: Submersed Aquatic Plant Map
Knowing which aquatic plants and their density is extremely important to lake and pond health. Native aquatic vegetation provides habitats for fish and other wildlife, whereas non-native or invasive species can pose a risk for their ecosystem by pushing out native species.
The submersed plant bio volume maps provide information about location, density, and the percent of the water column filled by plant material. These metrics are imperative to targeting plant control resources in problem areas that may not yet be visible from the surface. Repeating the mapping process after mechanically harvesting or using aquatic herbicides is a valuable evaluation tool to provide accountability and if necessary make adjustments to future management strategies.
