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.

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.

Proper 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.

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 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.
