What is the extent of the dredging?

To remove approximately 17,500 cubic yards of sediment from the three inlet tributary streams: Browns Creek, Waterlick Creek, Buffalo Creek, and two minor coves. The goal is to increase the water depth to approximately five feet.

What method of dredging is likely to be used? Proposals were received or evaluated in September 2020. The contract for Project 1 has been awarded to C&M Dredging and Dewatering, Leesburg, Florida, who will complete the collection and removal of sediment from Timberlake via hydraulic dredging with dewatering.

What are the requirements of the vendor? Vendor must furnish all labor, materials, equipment and services to hydraulically dredge/ transport approximately 17,500 cubic yards of accumulated sediment from five (5) coves to an adjacent approved disposal site, dewater the collected sediment, and return dewater to Timberlake.

This method will likely cause less impact on the lake environment, less impact on Timberlake Drive, fewer problems with disposal of sediment and better access to remove sediment from the inlet tributaries.

What is the proposed start date?

The WID trustees reviewed the responses to the Invitation to Bid and selected a vendor based on the overall score at accomplishing our goals for dredging.

The Trustees presented the selected vendor bid to the Robert E. Lee Soil and Water Conservation District directors to approve the project and project budget. Financing was finalized in the fall of 2020, dredging will begin March 2021, with a secondary start date in September 2021.

Where will the sediment go after it is removed from the lake?

The preferred process of dredging collects silt, sediment, and water, then filters the sediment down to very small particles, and returns the water to the lake. Because the sediment is no longer suspended in water, it reduces the net volume of sediment by 50 percent or more. The sediment will be placed in a walled area on the road side field of the Timberlake Pavilion. The field will be graded, sloped attractively, and grass will be planted to restore the use of the field.

How will we know the depth of the coves after the dredging?

The selected vendor will perform a post-dredge hydrographic-bathymetric survey to determine the volume of all material removed and to render an up-to-date topography of the lake bed.

I live on the main lake, how will I benefit from the dredging project?

If nothing is done, the lake will fill up with sediment as College Lake is doing now. If coves fill up. all lake property owners lose access to enjoy parts of the lake. Sediment is not static; regular rains, natural springs, storm water runoff, and construction upstream, deposits and moves sediment. Simply put: the lake is shrinking and the lake bottom continues to change. Over the last 20 years, many of our homes have been remodeled or demolished and rebuilt. If access to the lake in the coves is not maintained, the property value of all homes will decrease due to lose of access to the lake.

What is the total cost of the project?

A final cost has not been determined. The WID Trustees have studied other projects and many types of dredging to be able to determine a ball-park cost and are expecting the cost of the dredging project will be approximately $500,000.

How will the project be financed?

A bank loan from First Bank & Trust is paid through WID Tax collected by Campbell County Treasurer when real estate property taxes are paid. The term of the loan is 15 years.
