Woodglen Lake Facts

 Lake Surface Area = 12.5 acres
 Sediment Pool Capacity =
  160,000 cubic yards (CY)
 Current sediment in lake =
  32,500 CY
 Estimated annual sediment load   17 feet
  = 1,244 CY
                                   32,500 CY

Lake Restoration and Dredging Project

 Project Goals
 Restore sediment pool capacity
    Downstream water quality benefits
    Lake water quality
    Esthetics
 Improve lake water quality and habitat
 Stabilize stream segment
 Provide long term maintenance improvements
Dredging Alternatives


1. Mechanically dredge deposited
   sediment and haul wet




2. Drain lake and dry deposited
   sediment in place before hauling
Lake Barton Example

PRE-DREDGING:
An estimated
35,000 cubic yards
of sediment had
accumulated in
the lake, forming
islands and
reducing water
levels to less than
three feet in most
areas.
Lake Barton Example: Pre-Dredging
Lake Barton Example: Dredging in Progress

DREDGING:
Dredging took
place without
draining the lake.
Lake Barton Example: Dredging in Progress
Lake Barton Example: Completed Project
Lake Needwood Example

                               Lake Needwood:
                               Montgomery County, MD




Dredging:
The lake was drained and the
sediment was dried in-place.
Lake Needwood Example: Dredging
Dredge Alternative – In the Wet

 General Sequence
    Establish access and staging areas
    Conduct dredging utilizing barges
    Haul wet sediment to disposal site
     for drying
 Benefits
    Less weather dependent
    Quicker initial start to dredging
    Less potential for schedule extensions or delay
 Concerns
    Increased sediment handling effort at disposal area
    Potentially higher cost
Dredge Alternative – In the Dry

 General Sequence
      Initiate drawdown of lake
      Establish access and staging areas
      Establish diversion channels within lake
      Conduct dredging
 Benefits
    Higher daily sediment removal rates
    Minimal sediment handling effort at disposal area
    Potentially lower cost
 Concerns
      Very weather dependent
      Higher potential for delays due to weather
      Typically more odor from entire lake bottom being exposed
      Need to relocate/salvage fish

Lake Restoration

     In-lake forebay
     Wetland planting
     Shoreline stabilization
     Fish habitat
     Fish stocking


Fish habitat created from
      salvaged trees




                                                                   Lake Barton:

              Project Timeline and Coordination

   Community coordination at Design and Construction phase
   June 2013: Final Design
   July 2013: Construction bid advertisement
   September/October 2013: Begin dredging
   Project duration: 6 - 7 months
   Lake may be drained for entire project (dredging method
    depends on project bidding)
     Partial lake drawdown alternative to be evaluated

Woodglen Lake Dredging and Restoration

  • 1. Woodglen Lake Dredging and Restoration Department of Public Works and Environmental Services
  • 2. Woodglen Lake Facts  Lake Surface Area = 12.5 acres  Sediment Pool Capacity = 160,000 cubic yards (CY)  Current sediment in lake = 32,500 CY  Estimated annual sediment load 17 feet = 1,244 CY 32,500 CY
  • 3. Watershed  Drainage Area = 740 acres (1.15 square miles)  Pohick Creek Watershed  Sideburn Branch
  • 7. Woodglen Lake: Dewatering Basin Inactive Dewatering Basin Available Exclusively by DigitalGlobe ©2013 Microsoft Corporation © 2012 Nokia
  • 8. Lake Restoration and Dredging Project  Project Goals  Restore sediment pool capacity  Downstream water quality benefits  Lake water quality  Esthetics  Improve lake water quality and habitat  Stabilize stream segment  Provide long term maintenance improvements
  • 9. Dredging Alternatives 1. Mechanically dredge deposited sediment and haul wet 2. Drain lake and dry deposited sediment in place before hauling
  • 10. Lake Barton Example PRE-DREDGING: An estimated 35,000 cubic yards of sediment had accumulated in the lake, forming islands and reducing water levels to less than three feet in most areas.
  • 11. Lake Barton Example: Pre-Dredging
  • 12. Lake Barton Example: Dredging in Progress DREDGING: Dredging took place without draining the lake.
  • 13. Lake Barton Example: Dredging in Progress
  • 14. Lake Barton Example: Completed Project
  • 15. Lake Needwood Example Lake Needwood: Montgomery County, MD Dredging: The lake was drained and the sediment was dried in-place.
  • 17. Dredge Alternative – In the Wet  General Sequence  Establish access and staging areas  Conduct dredging utilizing barges  Haul wet sediment to disposal site for drying  Benefits  Less weather dependent  Quicker initial start to dredging  Less potential for schedule extensions or delay  Concerns  Increased sediment handling effort at disposal area  Potentially higher cost
  • 18. Dredge Alternative – In the Dry  General Sequence  Initiate drawdown of lake  Establish access and staging areas  Establish diversion channels within lake  Conduct dredging  Benefits  Higher daily sediment removal rates  Minimal sediment handling effort at disposal area  Potentially lower cost  Concerns  Very weather dependent  Higher potential for delays due to weather  Typically more odor from entire lake bottom being exposed  Need to relocate/salvage fish
  • 20. Lake Restoration  In-lake forebay  Wetland planting  Shoreline stabilization  Fish habitat  Fish stocking Fish habitat created from salvaged trees Lake Barton: Fish stocking by Virginia Game and Inland Fisheries
  • 21. Chesapeake Bay Preservation Areas  Buffer Restoration
