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.

Hydrographic Survey and Sub-Bottom Sediment Mapping as Part of Water Management Plan

Widespread Drought Highlights Several Needs for Accurate Lake Maps

As a widespread drought continues on throughout much of the country we are receiving 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 and accurate lake map has never been higher.  One agency told us they needed to have an idea as to what the lake surface area is and how the lakes elevation compares to lake volume.   They needed to complete a lake survey to make sure adequate water was available, so the pumps don’t run dry.  Another common challenge deals with the impacts of sedimentation in lakes.  A sediment survey can point out patterns and masses of build-up that can allow for a more focused dredge rather than a full-scale project.

Dredging is one of the most costly projects that a community or pond owner will incur during the life of a pond. Proper planning for a dredging project could mean cost savings. The Mapping Network understands the challenges and costs associated with locating and removing sediment. We specialize in accurately mapping bodies of water, calculating the water volume, collecting sediment depth samples at critical areas and monitoring the distribution of sediment over time.

Common questions from our clients:

  • Where is the highest sedimentation occurring?
  • How much sediment (in cubic yards) is in each cove?
  • If the lake is drawn down 5 ft, what would the shoreline look like?
  • How much water (gallons and acre-ft) is in the lake?
  • If we make each cove a minimum of 4 feet deep for boat access how much material do we need to remove?
  • By undertaking this mapping process will it save us money in the end?

Each of these questions can be answered by mapping the lake using The Mapping Network’s system. We are able to locate the problems areas and calculate the volume (in cubic yards) of material to be removed. The lake mapping data allows us to show the new shoreline if a lake is drawn down 1 ft, 5 ft, 10 ft, etc. Also, calculating water volume at various lake levels can be done.  One of the best aspects of the mapping process is it allows the owner and contractor to be on the same page. Successful planning and execution of the dredging project can ensue. We have seen clients save tremendous amounts of money by using The Mapping Network to survey their lake before undertaking the dredging process.

Below are a set of maps for a drinking water reservoir.  Originally built in the 1930’s, this lake has filled in substantially over time.  Now less than half the original lake capacity remains.  With a sustained drought there is a fear the lake will not be able to produce enough water for the city.  Engineers and the local government used The Mapping Network to survey the current lake depths along with charting the original lake bottom.  The final maps revealed a substantial sediment problem throughout the entire lake.  Plans are underway to remove sediment and regain much of the carrying capacity of the lake.

Sediment Survey for Dredging
