Coal Plant Ponds Bathymetry

The Mapping Network team surveyed two ash ponds for a coal power plant.   The purpose was to quantity and locate ash accumulation in the pond because it needed to be removed 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 used the information to assist with bids for dredging contractors to remove all the material.

The hydrographic survey included mapping the current bottom elevation of the ponds and also charting the hard bottom of the ponds.  Comparing the two models produces a map showing the location and amount of material has accumulated.

Sediment Volume Calculation for Dredge Project

The Mapping Network and Aquatic Environmental Services completed a sediment survey for a lake near Atlanta, Georgia.   The current water depths were mapped as well as the depth to hard bottom.  The difference between the current water depth (top of sediment) and the hard bottom is the amount of soft sediment that can be removed to bring the lake back to the original depths.  The client is preparing for dredging proposals for two coves and they needed to know the location and amount of material to be removed to bring the coves back to the original lake bottom.

Bathymetry and Sediment Survey of Lake in Peoria, Illinois

A property association in Peoria, Illinois needed to quantify sediment build-up in their coves.  The Mapping Network created a hydrographic and sediment survey of the two lakes and 20 coves.   The amount of sediment in each cove was calculated along with other vitals stats about the current lake condition.  A watershed map was also generated to help understand where sources of sediment are coming from.

Hydrographic and Sediment Survey of Lake in Cleveland, Ohio

The Mapping Network created a hydrographic and sediment survey for a property owners association in Cleveland, Ohio.   The main lake inlet has shallow water because sediment settles out at the mouth of the stream, creating deltas. These deltas impede fish migration, act as bedding areas for nuisance aquatic species, hinder recreational activities such as swimming and boating, and force property owners to extend their docks.

The POA installed two sediment basins to capture sediment coming from the north but as you can see from the watershed map, much more sediment is arriving from the east (this includes residential areas and a golf course).   The Mapping Network sampled the sediment structure and mapped the sludge thickness to help the client in the dredging bid process.  Part of the report included understanding sources of sediment and how activity within the watershed will ultimately affect the lake.   Below are maps showing the current water depth, sediment thickness, and total watershed.

Hydrographic and Sediment Survey of Lake in Kansas City, MO

The Mapping Network created a hydrographic and sediment survey for a property owners association in a suburb of Kansas City, Missouri.  The client was experiencing an increase in sediment on the main inflow and also 7 other coves.  Residents were having difficulties accessing the main body of the lake from their docks due to shallow water.  The POA needed to know how much sediment had accumulated in each cove to budget for removal in the near future.  As a result of the lake survey the POA not only has an understanding of the amount of sediment in the coves, but they also have an accurate map of the entire lake.  This map will be used by the property owners as a fishing map and as a baseline for future monitoring of sedimentation.

Lake Bathymetry Study of Pond in St. Louis, Missouri

The Mapping Network and Leisure Ponds teamed up to create a bathymetric study for a pond on a commercial property in St. Louis, Missouri.   Up-to-date water depths and volume are required for treatment applications, fisheries management and monitoring sedimentation rates.   Jim Darlington, owner of Leisure Ponds also generated a report on the health of the pond to ensure proper management and continued enjoyment for employees.

Quantifying Sediment in a Lake After a Flood Event

The 2013 Colorado floods were a natural disaster resulting from heavy rain and catastrophic flooding. The impact from this event was a large accumulation of sediment in the areas reservoirs.  One of these lakes near Denver had a remarkable amount of soft sediment and rock deposited into the lake.  In order to receive funding for removal of this new sediment, the ownership of the lake was required to provide quantitative proof. The Mapping Network used professional GPS and sonar equipment to survey the existing lake bottom and also locate the original lake bottom.  Our team generated current lake contour maps, sediment maps and also isolated the main problem areas.  3D models of sediment were created to calculate the amount of material needed to be removed.  The end result provided the lake owner the exact information needed to quantify the amount of sediment that needed to be removed and aid in the bid process for removal.

Having an accurate, up-to-date lake survey on file is critical to managing your resource.  Not only will it assist in making management decisions but it serves as a baseline for monitoring changes in sediment over time.

Drought Highlights Urgency for Understanding Current Water Volume of Lakes and Rivers

Bathymetry Study on Rivers

Widespread drought over the past couple years has resulted in many phone calls from homeowners, engineers and government agencies concerned about water levels in their lakes. Whether it be for recreation, sediment build-up or monitoring sources of drinking water, the importance of having an accurate water depth map has never been higher.

We are highlighting two recent projects involving rivers as drinking water sources. River systems are continually evolving and the need to have up-to-date bathymetry is necessary for municipalities to understand the water capacity.

The first project was for a medium size city needing to construct a new intake on the river. Engineers needed to identify the optimal location of the intake. Bathymetry of the river also gave city engineers the ability to calculate total water capacity in the river and what the capacity would be at each elevation in case of a drought.

The second project was very similar in that the municipality had three segments of a river plus a 75 acre lake that provided the city with water. The city has a large agricultural production plant that consumes a tremendous amount of water. As the recent drought has lingered, the city was concerned about providing enough water to its citizens. They needed to complete a bathymetric survey to make sure adequate water was available, so the pumps don’t run dry. If there wasn’t enough water in their current inventory the city would have to run pipe 3 miles to another water source. The resulting study indicated significantly more water was available than originally thought so for now the city will not need to implement any emergency plans.

Bathymetry and Sediment Survey of a Lake

The Mapping Network and their nationwide group of partners receive many calls each week about sediment issues on lakes.  More often than not, these callers have a fairly good idea about the state of their lake from simply looking at if from the shore on while on the boat.  However, trying to quantify the severity of sedimentation and planning for a potential dredging project is much more difficult.  This is where our experienced teams come into play.  We have the tools, knowledge and experience to accurately survey the current lake depths along with mapping the sediment thickness in the lake.

Below is an example of a lake that had sediment accumulating in the usual spots (inflows) however there were a couple other problem areas where new homes had recently been built.  The HOA used this map to plan for dredging in the main inflow of the lake and also created a bulletin to property owners about the importance of controlling erosion into the lake – eventually this will lead to more dredging in the future.

A lake surveyed by The Mapping Network included creating a contour and 3D shaded depth map of the current lake depths.  Also a sediment thickness map of the entire lake was generated.
