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, we play an active role in maintaining the “healthy lifestyle” of a pond through the management program we choose and implement.

A properly maintained lake or pond often has aeration, healthy riparian buffers and well established populations of beneficial aerobic bacteria. This integrated approach to lake and pond management helps prolong the life of your waterbody, making it healthy and enjoyable for you and the aquatic life which inhabit it. But, even well maintained lakes and ponds, over time, will have to face some amount of dredging, which will likely be one of the most costly projects that a community or pond owner will undergo during the life of their lake or pond.

describe the imageProper planning for a dredging project could mean cost savings. SOLitude Lake Management recommends that you have a bathymetric and sedimentation study performed every three to five years (in conjunction with the community reserve study) to make certain that the bottom of your pond isn’t changing more rapidly than you are anticipating. Having the study performed on a regular basis will help to establish patterns and will assist in determining the size, magnitude, necessary budget, and timing for future dredging projects.

Above and beyond dredging, bathymetry and sedimentation mapping can be used for many other purposes. Bathymetry will provide much needed pond information such as precise surface acreage and depths. This knowledge can provide a new world for pond owners and managers. It can help you properly place aeration or structural fish cover within the pond, provide accurate information for fish stocking and can even give fishermen an idea of where the fish are hiding, should the lake or pond be used for fishing.

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 engineers to create an efficient removal plan.  Dredging contractors can bid with confidence on how much sediment is actually in the lake.  The homeowners will ultimately benefit most from having an initial hydrographic survey because they will be able to control the project from start to finish – taking out the guess work and making sure their lake is restored for the lowest cost possible.

Bathymetry, Dredging and Sediment Maps – Solitude Lake Management

Mapping, Dredging and Reserve Factor by Solitude Lake Management

If you live in a community governed by a Homeowners Association (HOA), or you are a community manager tasked with managing an HOA, I am sure you are familiar with the statutory requirements placed on you to maintain budget reserves and to complete formal Reserve Studies for your community in most states every 3-5 years.

So many important issues are addressed by these studies, all of which help to prepare communities for significant future repair and replacement expenses. In most cases, the Reserve Specialist preparing the report is able to identify very accurate estimates for the expected life of the community assets, and the corresponding specific costs for making significant repairs or replacing those assets as their expected life comes to an end. As valuable as these studies are for communities, we find they are typically missing one key piece of information that will, in many cases, affect the accurate planning and budgeting for the single most expensive expenditure a community will ever face…DREDGING.

All communities have stormwater management facilities incorporated into their overall development designs. In many cases, these BMPs take the form of ponds or lakes. These stormwater ponds and lakes are designed to collect all stormwater flowing in from the community’s impervious surfaces such as roofs, sidewalks, driveways, and streets. In doing so, all of the sediment, grass clippings, leaves, fertilizer, other organic matter, and pollutants contained in this stormwater will settle to the bottom of the pond in between rain events so that the next time it rains, clean water flows out of the outflow as new contaminated water comes in through the inflows.

This is good news for our streams, rivers, bays, and oceans, as these ponds and lakes filter runoff water and make sure that only clean water is discharged into our natural waterways. However, if these stormwater ponds and lakes are left unmanaged, what is a dream for Mother Nature can be a nightmare for the community. The biggest of these nightmares comes when a community realizes their pond or lake has enough accumulated sediment and organic matter that it needs to be dredged in order to continue to function properly and as designed.

Although Reserve Studies will typically address the potential need for dredging, and maybe even go so far as to give you some data on the typical life expectancy of the BMPs and cost to dredge them, these are rarely accurate or specific to your particular site. These numbers are averages, and mostly educated guesses, as the information required for Reserve Specialists to be able to provide you detailed and up-to-date accurate assessments and costs for dredging are not available to anyone without bathymetry having been performed.

As you might imagine, every pond or lake is different, and the demands put on these BMPs vary based on the size of the overall watershed, climate and weather conditions, landscaping and fertilization practices, level of ongoing annual lake and pond management activities, etc.

If you want to accurately evaluate the current sediment accumulation in your lake or pond, and project forward to when it will need to be dredged, and how much it will cost to do so, there is only one choice…BATHYMETRY.

Bathymetry is the process whereby the surface of the lake or pond is plotted using GPS technology, and each of the GPS points recorded is correlated to the corresponding depth of the lake or pond at that specific point. After collecting thousands of surface points with their associated depths, a three dimensional model of the bottom of the lake can be developed. With this information, the current maximum storage capacity (volume of water) of the pond can be quantified, and compared to original design plans to determine how much of the original storage capacity has been displaced by the accumulation of sediment and organic matter at the bottom of the pond.

Once this information is known, it is very easy to get specific cost estimates for dredging, as you will know the exact amount of material that needs to be removed. If you find that dredging is not needed now, which is what everyone hopes, you will then be able to use the bathymetric data to plan for future dredging. Also, now that you know the current amount of sediment accumulation, and you know how old the lake or pond is based on original construction plans, you can figure out the annual sedimentation rate from the time the lake or pond was originally constructed to now and then project that rate forward to compute how many years from now dredging will in fact be required.

Bathymetry provides community managers and boards with powerful information with which to manage their stormwater lakes and ponds, and most importantly, provides them with the tool they need to quantify and plan for what will in many cases be the single most costly expense the community will ever face. No budget or replacement reserve planning is ever complete for those communities with lakes or ponds if they do not perform bathymetry on a periodic basis.

Georgia HOA Uses The Mapping Network for Sediment Mapping and Analysis

Aquatic Environmental Services, Inc (Ball Ground, GA) and The Mapping Network recently completed a mapping project for a home owners association in Georgia.  The lake has a history of significant sediment problems.  Aquatic Environmental Services, Inc mapped the lake in 2007 and the lake had been dredged shortly thereafter.  Now, four years after dredging the lake, homeowners are having difficulties navigating through the coves.  Aquatic Environmental  Services, Inc., updated the lake map a week ago to note current water depths and mark sediment depths.

Another component of the project was to calculate the amount of material needed to be removed in order to make the coves 4 foot deep. 3D models were generated to show how much sediment had accumulated in each cove.  Contour maps were also made for each cove and given to the lake manager and engineer to review for dredging planning.  The Mapping Network then created cut-fill calculations and maps based on the specifications of the lake manager.  The HOA will then use this information as part of the bid package given to dredging companies.  Presenting the precise plans took out the guess work and keep all the dredging contractors on task.

Information gathered during the lake mapping process helped Mr. Grimes’ client better comprehend the level of sedimentation building up over time in the lake.  The resulting map provided the baseline depth profile needed for long-term sedimentation monitoring.

Here at The Mapping Network, 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.  We have a nationwide group of professionals specializing in all facets of lake management.

The bottom line – This powerful information allows for smart management and planning decisions and will serve as a baseline for future projects.  A great value! 

In the maps above, the HOA needed the depths of the cove to be a minimum of 4 foot for boat access. Mapping Network located the areas where the current depth was less than four feet, which was the dredging zone. The Mapping Network calculated the dredging area and volume. The current lake bathymetry (left) and the post-dredge contours (middle)are shown in blue shading. A cut-fill model (right) shows areas of cut needed to reach the goal.

NPDES is Here – Pond Owners and Managers Take Notice!

SOLitude Lake Management reminds pond and lake owners to follow the new NPDES permit rules…

After many years of judicial and legislative battling, the NPDES permit for aquatic pesticide applications has been finalized and went into effect on October 31, 2011and there is a high probability that this new permit will directly affect you and your pond. NPDES stands for National Pollutant Discharge Elimination System, and it is the primary federal legislation that regulates point source pollution to the waters of the U.S. Although aquatic pesticide applications were previously exempt from this permitting requirement, recent judicial reinterpretation of the law has mandated that the residues resulting from these applications should be regulated within the same framework as other water pollutants. So basically, if you own or manage a property with a pond, then you will be responsible for making sure that all pesticide applications related to the pond meet the requirements of the new permit. Some of the activities that will be regulated under this permit include algae and weed treatments in the water, shoreline vegetation control, and mosquito control. And the most important part of this new law is that as a decision maker or financier for the applications, you are just as liable for permit compliance as the applicator. SŌLitude Lake Management utilizes a specialized lake management software program to manage our application data, and many facets of permit compliance are already part of our daily operations. We will work with our clients and our industry partners to ensure that all of our operations are compliant with the permit requirements, and can provide consulting services for any operator in the development of a NPDES Pesticide General Permit compliance program

Contact our office today to schedule a consultation with our staff to make sure you are prepared to answer those VERY important questions from homeowners and Board members.
