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.

For the best results in mapping, it’s best to consult with a lake management company equipped with the very latest in GPS mapping technology.  Along with standard contour maps, The Mapping Network creates virtual media solutions on YouTube including a fly-over video and virtual underwater virtual swim-through.  With this knowledge, you can add layers of depth to the information you seek to maintain a beautiful lake.

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.

Lake Volume Analysis Study

GPS Lake Mapping Accurately Accounts for Current Water Capacity

It is critical to know the exact acreage and depth range of your lake to make sound management decisions.  Precision GPS lake mapping conducted by The Mapping Network utilizes highly accurate procedures and equipment for data collection.  Utilizing sub-foot accurate GPS units and hydro-acoustic depth-sounding equipment, our team logs data points for extremely accurate location mapping.  Our clients are able to accurately understand how much water is available in their lake at any number of water levels.  Best of all, this information is up-to-date and can be customized to any requirement.  Need to know how many gallons of water are available when the lake is at full pool?  How about if the water level is down 5, 10, or 15 feet?  We can even calculate the amount of water in certain depth ranges (example: volume for 5 to 6 feet).  Current, accurate results are our specialty.

A GPS Bathymetric Lake Map and Volume Analysis Study by The Mapping Network will help optimize your efforts to manage your lake or pond.
