As Summer Fades, Autumn is the Time to Clean Up Your Waterfront. Here’s Why.

The summer season saw lots of fun on the Central Texas Highland Lakes. The draw down which occurred early in the year provided opportunity for waterfront homes and business owners to see their waterfront channel and cove bottom areas for the first time in 9 years. Subsequent cleanup efforts paved the way for summer fun.

Hurricane season struck the Texas and Florida Gulf Coast areas hard this year. For those most affected by the storms, waterfront cleanup efforts will most likely take a back seat to other priorities such as property cleanup and reconstruction. For those who were not affected as much, now is the time to begin thinking about cleaning up that waterfront, cove, or channel.

If your waterfront is socked in with vegetation, cleaning it now makes good sense for two reasons. Growth is dormant in the winter months, so the fall cleanup will last through early spring. When growth of aquatic vegetation resumes in the spring, it will not have a substrate to grow in if it has already been removed. Most aquatic plants require three elements for growth: water, light and a substrate of sediment to grow in. Take one of these away, and growth is hindered.

The technology we use is portable, efficient, environmentally friendly, and most of all, very effective. Contact us today to get your waterfront ready for next year.

Even Though the Draw Down is Over, You Can Still Get Your Waterfront Cleaned for the Summer

BeforeandAfter_Dredging_Results_TexasSo the Lake LBJ draw down this year was the first one in nine years. It lasted about six weeks, but it did not offer the opportunity we had hoped for removing exposed sediment from your waterfront. This was mostly due to bad weather during the first three weeks of it.

Some lucky ones got work done. Others got equipment stuck in the mud. And most did not benefit from it at all. I’m happy to say that Clean Channel Dredging stayed busy, getting work done and did not get any equipment stuck in the mud.

The good news is this: you don’t need a draw down in order to get your waterfront cleaned for summer. In fact, 95% of the dredging on the lake happens when the lake is full. The technology we use is portable, efficient, environmentally friendly, and most of all, very effective.

Meeting the Challenge: Retention Ponds at Hill Country Galleria

portable-dewatering-plantOne of our most challenging assignments during Thanksgiving 2016: retention ponds at The Hill Country Galleria. Cleaning out the forebays for three ponds using what we now call the Elephant Trunk adapted to our primary work platform at Clean Channel Dredging.

The system normally uses a horizontal roto-tiller to lift silt and sediment from the bottom of the pond. It then uses a 6″ impeller and suction pump to draw in the sediment and discharge it up on the bank via a 6″ pipe into a mobile dewatering plant where solids are separated from the water. Dry solids are discharged on the bank ready to haul off. Clean water is returned to its source. Although geotubes are often more efficient, this portable dewatering system can be used where it is not feasible to use geotubes.

One of the ponds has a forebay with no access for our floating platform. The forebay is only about 75′ in diameter, but it has steep slopes on three sides and a rock gabion on the pond side. These conditions prevent us from moving our platform into the forebay directly to use the roto-tiller. In this case we removed the roto-tiller and adapted a suction hose assembly to the intake pump. We call it the Elephant Trunk. See photos.

LCRA’s Lake LBJ Draw Down Scheduled for January

As you may know LCRA will draw down Lake LBJ about 4 feet starting January 2, 2017 for six weeks. LCRA is doing this as a service to customers and waterfront homeowners as an opportunity to repair docks & retaining walls, as well as to dredge, remove debris and perform other maintenance work.

According to LCRA:

A permit is not needed for dock repairs, but all work must comply with the Safety Standards for Residential Docks on the Highland Lakes.

Residents and property owners wanting to perform dredging, remove debris or work on existing retaining walls during the Lake LBJ draw-down may do so under LCRA’s lake-wide permit from the U.S. Army Corps of Engineers, providing the work meets the requirements of the permit. This fact sheet has information on activities allowed under the lake-wide permit. Anyone wanting to conduct work under the permit must register with LCRA.

Please click on this link (or copy to your address bar) to view all of the information and complete any permits you might need:

Clean Channel Dredging will not be operating on Lake LBJ during the draw down period as we already have work scheduled at other locations. If you plan to use excavation equipment at your waterfront, be extremely careful. Surfaces that appear to be dry can have a water table just a few inches below.
Good luck with your draw-down opportunity.

Let us know if we can provide any information or assistance prior to or following the draw-down.
