Pond Water Depth and Excavation Plan in Atlanta, Georgia

The Mapping Network and Aquatic Environmental Services teamed up to create a bathymetric study and excavation plan for a homeowner near Atlanta, Georgia.  The owner wants to achieve a minimum 3 foot water depth in the entire pond.  3D models comparing the proposed lake bottom with the existing lake bottom and calculated the amount of hard material to be removed.  This critical information will be used to assist with bids for dredging contractors to remove all the material.

Proposed excavation plan to achieve minimum 3 ft depth in pond.

Water Pump Intake Bathymetry

The Mapping Network has extensive experience performing hydrographic surveys on intake channels for power plants and drinking water intakes. On the example below The Mapping Network conducted a pre-dredge bathymetric survey along with calculating the amount of material needing to be removed.  This information will be used to collect bids for dredging the area.

Tracking Lake Sediment in Virginia

Solitude Lake Management created a bathymetry and sediment volume study for a property owners association in Virginia. The pond was mapped to understand current water depths and to calculate the amount of accumulated sediment.  This timely analysis can facilitate future dredging and appropriate actions for maintaining a stable environment.

Post-Dredge Water Depth Verification

The Mapping Network completed a post dredge bathymetry survey to show the status of a  dredging project on a lake near Kansas City.   A comparison map of the pre-dredge and post-dredge depths was generated to verify the amount and location of material removed.   Areas still needing to be dredged are located and the dredging contractor will focus their efforts on those locations.  This verifies the dredging has reached the planned depths.

Bathymetry and Sediment Mapping in New Jersey

The Mapping Network was contacted by Solitude Lake Management to perform a bathymetric and sediment evaluation of a specific pond. This evaluation will then be used for Dredging of the area. We converted their Trimble SSF file of bathymetric data over to GIS data to then be used for mapping. Our Geospatial Analyst then produced three visuals: 3D Bathymetry Map, Contour Bathymetry Map, and a Sediment Thickness Map. These will provide the Technicians in the field great guidance for their dredging purposes.

Texas Sediment Survey for Dredge Planning

Pond Medics created a bathymetry and a sediment volume study for a property owners association in Texas. The lake was mapped to understand current water depths and to calculate the amount of accumulated sediment.  This is essential information to plan and help the POA manage the future dredging project.

Power Station Predredge Survey for Ash Pond Dredging Project

The Mapping Network team performed a hydrographic predredge survey on a large ash reservoir for a power station in Kansas.   The purpose was to quantify and locate ash accumulation that needed to be dredged per EPA regulations.   By comparing the original bottoms of the ponds with the current bottom depths, a computer model calculated the location and amount of material.  The power company and dredge contractor will use this information to assist in validating that all the material has been removed.
