When thinking about mapping a lake, it’s good to have a basic background of how the different methods of GPS can affect the quality of your data and ultimately the accuracy of your map. Staff at The Mapping Network have been using GPS technology to map lakes since the 1990’s and we want to quickly cover some basics about the primary GPS collection methods available today. It is important to understand how each type of…
The Mapping Network Hydrographic Survey Team exceeds expectations for Property Owner Association. Sediment problems are inevitable in all lakes and at some point removal is required. Lake dredging and/or excavation can be an expensive process and requires accurate planning to be as cost-efficient as possible. A lake Property Owners Association (POA) had been dealing directly with the challenges associated with sedimentation in their lake. The POA decided they needed to quantify the sediment problem…
The Mapping Network is offering a “recreational level” lake mapping option for people looking for a general understanding of their lake or pond. Data is collected by one of our lake mapping partners (find your closest provider here >> Lake Mapping Partners) using a Lowrance HDS sonar system. We call these recreational level maps where general contours and depths can be seen and should be used as general reference maps. These maps provide insight into…
Greg Grimes (Aquatic Environmental Services, Inc) was contracted to assist with preliminary planning of a lake for a client in Georgia. Greg said “by utilizing the lake design tools available through our partnership with The Mapping Network, we were able to see how large the lake would be, the max depth, average depth, size of the dam and also the watershed.” With the map the client was able to see potential challenges with a limited…
Solitude Lake Management completed a certified hydrographic survey and sediment survey as part of a dredging analysis report. This 29 acre lake, originally built in the early 1900’s has an average water depth of 2.6 feet. Through sediment sampling, the average soft sediment thickness is 2.1 feet. Over time the lake has lost almost half of its original capacity to sediment. The estimated sediment volume was calculated and shown on a map. This will allow…
Here at The Mapping Network, we understand 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 fluffy sediment (in cubic yards) is in each cove? If the lake is drawn down 5 ft, what…

The Mapping Network Hydrographic Survey Team exceeds expectations for Property Owner Association. Overview: A lake property association (POA) has been dealing directly with the challenges associated with sedimentation in their lakes for over 20 years. In 2002 The Board of Directors created a 30 year sediment removal and management plan (2002-2031). They looked at 3 different options: A) hiring a dredging professional, B) leasing dredging equipment and use current POA staff to operate, or C)…
Using a GPS Lake Map to Create Management Plan Jim Darlington, President of Leisure Ponds, mapped a pond in the St. Louis area for a residential Home Owners Association. The pond surveyed was approximately 2.7 acres and had shown warning signs of sedimentation. GPS Lake mapping was conducted on site to reveal the true lake depths of the ponds. In addition to the bathymetric survey, sedimentation depths were collected and a model of sedimentation levels…
