Dredging
Rocky River is sending 50,000 cubic yards of sediment nearshore
Rocky River Harbor's 2026 maintenance package divides approximately 59,000 cubic yards between two destinations: about 50,000 cubic yards to a nearshore area east of the harbor and 9,000 cubic yards to a designated open-lake area.
Published scope and current milestone
The 27 May 2026 USACE release controls the contract, contractor, total planned quantity, 50,000/9,000 placement split, schedule, authorized depths and sediment-testing statement. The DVIDS story is an official mirror. The 29 May video confirms active mechanical dredging in Rocky River but not final quantities, completed placement or accepted channel condition. The 2024 Work Plan release is limited to earlier environmental coordination and sediment-sampling preparation.
Dredging quantity and delivery implications
The split affects scow cycles, placement controls and the evidence needed at completion. A total dredging quantity alone cannot show whether the nearshore and open-lake routes were both used as planned or whether the authorized channel was restored.
Evidence conclusion
Survey, placement and acceptance evidence
The contract and planned split are clear, and USACE field video confirms mechanical dredging started. Delivery still needs three separate records: measured excavation, route-by-route placement and post-dredge channel condition. Until those are published, report the 50,000 and 9,000 cubic yards as planned allocations rather than completed quantities.
Outstanding evidence
- Measured excavation against the approximately 59,000-cubic-yard scope
- Nearshore placement volume and location east of the harbor
- Open-lake placement volume and designated-area compliance
- Sediment testing and agency coordination for both routes
- Post-dredge hydrography across the 6-to-10-foot authorized channel
- USACE completion and acceptance by the August 2026 target
