Supplemental funding for this project was appropriated for the Buffalo Bayou project to address the following Hurricane Harvey damages:
The Cedar Bayou project experience significant shoaling during Hurricane Harvey. Supplemental funding for this project was appropriated to perform critical maintenance dredging and restore depleted dredged material disposal capacity from the dredging operations.
Dredging operations were complete in December 2019.
A contract to restore depleted dredged material disposal capacity is scheduled to be award in 2020. Currently there is sufficient funding to perform minimal placement and improvements. Additional funding in the amount of $2.7 million is required to complete all Hurricane Harvey related damages for this project.
Supplemental funding for the Channel to Port Mansfield Project was provided for the removal of shoaled material along the nearly 13-mile channel (Gulf of Mexico to Port Mansfield) and construction of a beneficial-use site needed to serve as a placement area for the shoaled material.
Supplemental funding was appropriated to the Corpus Christi Ship Channel project in order to address several Hurricane Harvey-related damages, including:
Supplemental funding was appropriated for the Gulf Intracoastal Waterway to address repairs to the Colorado River Lock structure, critical dredging requirements and repair of shoreline erosion along the GIWW. Repairs to the Colorado River Locks and dredging operations were completed in 2018. The shoreline erosion repair contract was awarded in September 2019 and is expected to be completed in January 2021.
Supplemental funding was appropriated for the Houston Ship Channel for a variety of damages along the Houston Ship Channel, including:
Supplemental funding was appropriated for this project to perform emergency maintenance dredging of shoaled material resulting from Hurricane Harvey. The contact was awarded in February 2020 and is scheduled to be completed in January 2021.
Supplemental funding was appropriated for this project to repair Hurricane Harvey damages to the Wallisville West Levee road. The contract is scheduled to be awarded in March 2020 and is expected to be completed in December 2020.
Supplemental funding was appropriated for the Clearwater Lake Project to address multiple floodwater-caused issues including bank erosion, destruction of some facilities, and damage to spillways and basins. The project will ensure continued flood water management by the lake and associated structures.
Supplemental funding was appropriated for the MKARNS Project to provide navigation and flood risk reduction. The Little Rock District is completing multiple repair actions to ensure the continued function of the MKARNS. Project actions include dredging, rock training structure and bank stabilization, scour hole and levee repairs, replacing bulkhead structures, replacing sump pumps, and various gate and dam repairs.
Supplemental funding in the amount of $879,000 was appropriated for the Fort Gibson Lake flood risk reduction contract to remove and replace the slip lining and flap gates on Dike 10 (Wagoner Levee). The work will reduce the likelihood of localized flooding on the land side of the dike forming the western boundary between Fort Gibson Lake and the northeast corner of Wagoner, Oklahoma.
Flap gates prevent water from pooling on the land side of the dike during periods of heavy rainfall. Flap gates work by allowing water to flow into the lake from the land side of the dike. When lake levels rise above the drainage works the force of the lake closes the gates and preventing flooding into residences in Wagoner.
Slip liners prevent seepage from the pipes that run through a dike or levee. The original slip liner, installed during Fort Gibson Lake’s construction between 1942 and 1946, will be replaced with a new high density polyethylene liner.
The project has been delayed by high lake levels brought on by high levels of rainfall in the Grand Neosho Watershed.

Houston and Galveston channels dredging projects
Beach nourishment project west of 61st street is in conjunction with the broader project to dredge the Houston and Galveston channels. The nourishment project, a collaboration between USACE, the Texas Land Office and the Galveston Park Board of Trustees, is expected to place up to 711,000 cubic yards of material along the existing beach.
