Bathymetric Studies: The Tools You Need to Help Budget for Lake and Pond Dredging

(Source: Solitude Lake Management Newsletter. http://www.solitudelakemanagement.com/) Did you know that a lake or pond, left to nature, has a distinct lifespan? Sediment in stormwater runoff, grass clippings, leaves, and other yard debris that find their way into the lake or pond add nutrients and accumulate on the bottom. This accumulation of nutrient rich sediment will gradually reduce the depth and volume of the pond while also feeding harmful algae growth. As owners and managers of ponds,…

Hydrographic Survey of Lake in St. Louis, Missouri

The Mapping Network and Leisure Ponds teamed up to create a hydrographic and sediment survey for a property owners association in a suburb of St. Louis, Missouri. The client was experiencing an increase in sediment on the main inflow and also 2 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…

Start a Sediment Plan with an Accurate Lake Map

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…

Certified Hydrographic Survey and Sediment Map – Solitude Lake Management

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…

Property Owner Association Uses Hydrographic & Sediment Surveys to Create Strategic Sediment Removal Plan

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…

New Lake Planning

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…
