Why Lake Mapping?

Lake mapping helps us see and understand what affecting water quality and overall lake health. We use a few maps to manage lakes:

  1. Bathymetric Map
  2. Bottom Hardness Map
  3. Submersed Aquatic Plant Map

Bathymetric 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.
