Waterway: The sites are located in the Rogue River from approximate RM 84-101. The location of the ordinary high water mark (OHWM) shown on the project drawings has not yet been verified by the Corps. If the Corps determines the boundaries of the OHWM of the Rogue River is substantially inaccurate a new public notice may be published.
Project Purpose: To ensure safe vessel navigation within the Rogue River.
Project Description: The applicant is seeking a 10 year authorization to dredge and discharge up to 1,050 cubic yards (cy) of sediment below the OHWM of the Rogue River, as needed, annually, for vessel navigation access within a 17 mile reach of the Rogue River. The depth of substrate to be discharged and dredge prism extents would vary annually. The applicant has identified an adequate water depth for vessel under keel clearance as two feet at 8 of the 9 dredging areas. The maximum dredging depth would not exceed two feet at these areas; the dredging depth would be generally less than one foot given existing surface water levels at the riffle locations when the applicant conducts dredging. At the applicant’s loading dock area the applicant has identified a needed water depth as 4 feet due to a recent influx of sediment at this location. The maximum dredge prism lengths and widths identified below are the extents in which dredging would occur; however, the entire dredge prism would not always require dredging to maintain adequate vessel under keel clearance. The applicant would generally conduct dredging in an area measuring approximately 50 to 200 feet in length with dredging occurring in some years, at low surface water levels, to up to 500 feet in length. The applicant’s dredge prism would measure up to 16 feet wide. The maximum annual dredging volumes listed below are recognized as upper thresholds; the applicant would likely discharge less volumes than estimated given surface water flow conditions and methods.
The applicant would conduct dredging using vessel prop-washing methods working from within the waterway. The excavator would access the river from adjacent upland areas and would work within the water. Alternatively, the applicant may also discharge temporary fill in the form of bulk bags to control the riffle height and avoid and/or minimize the need to conduct dredging.
Prop-wash method: The applicant would remobilize all sediments downstream of the primary dredging sites when using prop-washing dredging methods; these sediments would be relocated and re-distributed via river flow below the OHWM of the Rogue River.
Excavator method: The applicant would operate the excavator in the Rogue River when undertaking dredging activities using this method. The applicant would mobilize and demobilize the excavator by driving it from uplands to in-water dredging locations and vice versa. The applicant would relocate sediments to one side of the dredging area and ensure they are spread evenly within the water column when using excavator dredging methods; these sediments would be relocated and re-distributed via river flow below the OHWM of the Rogue River.
Bulk bag method: The applicant may also utilize bulk bags at 8 of the 9 locations to temporarily control the configuration of the river thalweg to allow passage of vessels through the riffle. The applicant’s use of bulk bags is intended to reduce the need to physically alter the stream channel. The bulk bags would measure approximately 45 inches wide, 45 inches long and 65 inches in height. The bulk bags would result in a discharge of up to 3 cy of fill material below the OHWM of the Rogue River per bag; multiple bags may be used to control surface water levels at the riffle locations. The applicant would construct the bulk bags in uplands using rock fill material and would place the bulk bags using an excavator and/or an off-loading arm affixed to a vessel. The applicant would access the waterway from uplands to both place and remove the bulk bags in the river. The applicant would orient the bulk bags in a singular row to temporarily elevate the riffle elevation by approximately one foot to allow vessel passage through the riffle. The applicant would generally only place the bulk bags during anticipated low surface water levels but may place and leave them at the riffle sites from May 1 through October 3 annually, if needed. The applicant would place signage upstream and downstream of the bulk bag configuration to alert the public to the partial obstruction within the waterway. The applicant would also mark the bulk bags with reflective markers and would place a red buoy at the channel side of the bulk bag configuration to signify the location of the navigation channel for watercraft to safely traverse the riffle location.
The applicant would conduct prop-wash dredging and excavator dredging during the Oregon Department of Fish & Wildlife (ODFW) preferred in-water work window for this reach of the Rogue River or under an approved extension; 15 June to 31 August. The applicant anticipates a typical need to discharge bulk bags during July or September but depending on the surface water levels at the time of year there could be a need to discharge bulk bags around May 1 of the calendar year. The bags would be removed from the river by October 3 of the calendar year at the latest.
The applicant’s dredging work and bulk bag placement are anticipated to take 30 minutes per site with multiple sites being able to be accomplished in one day if needed. Some sites may require additional follow-up dredging to maintain adequate vessel under keel clearance due to fluctuating water levels within the Rogue River during the applicant’s operating season; May 1 through September 30. The applicant does not anticipate affecting riparian vegetation along upland or in-water access routes to the dredging or bulk bag discharge locations.
The details of each work location are described below:
Site Name Dredge Prism Length (linear feet) Dredge Prism Width (feet) Required water depth (feet) Maximum Annual Dredging (CY) Potential use of bulk bags?
Loading Dock 150 30 4 200 No
Notes: The applicant would enter the north side of the Rogue River at their shoreside facility in Grants Pass to conduct dredging at their Loading Dock area. Dredged material would be discharged south of the dredging site in the center of the Rogue River and evenly spread out.
Middleton Island 50-500 16 2 100 Yes
Notes: The applicant would utilize the Laithrop Island boat ramp at the Laithrop County Park located on the south side of Rogue River to access this dredging location.
Whitehorse Park 50-500 16 2 150 Yes
Notes: The applicant would access the dredging site from primarily from Dindsdale Farms located on the south side of the Rogue River. The applicant may also utilize the Whitehorse County Park for excavator access to the Rogue River.
Wharton Riffle 50-500 16 2 100 Yes
Notes: The applicant anticipates primarily utilizing Griffin Park located on the west side of the Rogue River to access this dredging location. The applicant may also use the existing boat ramp located on the east side of the Rogue River for excavator access.
Brushy Chutes 50-500 16 2 100 Yes
Notes: The applicant would place bulk bags with an off-loading arm affixed to a vessel at this location.
Robertson Creek 50-500 16 2 100 Yes
Notes: The applicant would utilize private property located on the west side of Rogue River to access this dredging location.
Robertson Bridge Turn 50-500 16 2 100 Yes
Notes: The applicant would utilize private property located on the west side of Rogue River to access this dredging location.
Two Bit 50-500 16 2 100 Yes
Notes: The applicant would utilize private property located on the east side of Rogue River to access this dredging location.
Hog Creek 50-500 16 2 100 Yes
Notes: The applicant would utilize an existing private road located on the west side and boat launch located on the west side of Rogue River to access this dredging location. The applicant may also utilize the Hog Creek County Park boat ramp located on the north side of the Rogue River for excavator access to the river.
Dredged Material Testing: Project sediments were evaluated in accordance with the Sediment Evaluation Framework for the Pacific Northwest (SEF). The interagency Portland Sediment Evaluation Team (PSET) implements the SEF for the Corps Portland District. The PSET determines the need for sediment testing based on the physical properties of dredged material, historical sediment quality data from the project and adjacent areas, current and historical land uses in and adjacent to the project area, and proximity of the project area to contaminant sources. The PSET has determined that no further testing or evaluation of the project sediments is necessary and that the project sediments are suitable for unconfined, aquatic disposal and exposure.
The proposed project includes future maintenance dredging. Prior to each maintenance dredging cycle the applicant would be required to coordinate with the Corps and the PSET to determine if additional sediment testing is required.
Mitigation: The applicant proposes to avoid and minimize impacts from the project by
incorporating best management practices such as a dredging operation plan which
includes the use of erosion control measures and turbidity monitoring as well as working
within the Oregon Department of Fish & Wildlife preferred in-water work window to minimize impacts to aquatic species. The applicant has provided a proposed compensatory wetland mitigation plan which details aquatic resource avoidance and minimization efforts to offset losses of waters of the U.S. that may result from the proposed project. The Corps will determine the type and amount of compensatory mitigation necessary to offset environmental losses from the proposed project.

Additional Information: The Corps issued a 30-day public notice for the project proposal on May 25, 2018. The Corps received multiple comments in response to the public notice. The applicant’s permit application was withdrawn following completion of the public notice process and the Corps did not render a permit decision on the project. The applicant has re-engaged the Corps to obtain authorization for the proposed dredge and fill activities in anticipation of a low-surface water year in the Rogue River during their vessel operating season. The Corps is soliciting additional public comments to inform our evaluation.
The applicant has received previous authorization from the Corps for similar work in this reach of the Rogue River at 5 locations. Consistent with the Corps May 25, 2018 public notice, the applicant proposes 4 additional dredging sites: Middleton Island riffle, the Robertson Creek riffle, Robertson Bridge Turn riffle, and their loading dock area in Grants Pass, Oregon. The applicant has identified these additional dredging sites as needed locations to facilitate operation and use of their vessels.
The applicant is seeking a 10-year maintenance and dredging disposal authorization, including the use of bulk bags described above, based on site and surface water flow conditions within the Rogue River.
