USACE scheduled Morrish-Wallace Construction's USD 628,000 Sandusky Harbor maintenance campaign to start on 6 October. Approximately 109,000 cubic yards are planned from the Moseley and Straight channels, with 100,000 cubic yards routed to nearshore nourishment and 9,000 cubic yards to a designated open-lake site. The announced start and 1 November completion target remain distinct from verified field progress.

The current award links two channels to two placement routes

The 6 October USACE release identifies Morrish-Wallace, the current price, mechanical method, channels, planned quantity, placement split and working dates. The August 2024 harbour factsheet supplies authorized depths and the older annual-maintenance baseline. A 2023 campaign used hydraulic dredging and the Cedar Point Causeway wetland route, so its method and quantity are not carried into the current record.

Nearshore benefit depends on route-specific delivery evidence

The current plan sends more than 90% of the announced material to a nearshore site, where USACE expects currents to redistribute sediment along the coastline. That makes dredged-material management part of the navigation result rather than a disposal footnote. Sandusky's federal system includes project depths from 21 feet in the Straight Channel to 26 feet in the Moseley Channel. Commercial access and coastal sediment reuse therefore require separate evidence: one ledger for excavation and restored channel geometry, another for delivered quantity and placement performance.

Evidence conclusion

Production and acceptance evidence remains outstanding

The release establishes an awarded package and scheduled 6 October start and 1 November completion, but it does not verify actual mobilisation, name the plant, publish daily output or provide post-dredge surveys. The 100,000 and 9,000-cubic-yard figures are planned routes, not placement receipts. The separate 2025 campaign removed approximately 9,000 cubic yards to open water and cannot be counted toward 2026 production. A completion notice should reconcile mechanical excavation, both destinations, channel depths, schedule and final contract value before the campaign is treated as accepted.

Outstanding evidence

  • Named dredge, scows, tugs and production sequence
  • Measured output from the Moseley and Straight channels
  • Nearshore and open-lake placement receipts
  • Post-dredge hydrography and navigation release
  • Completion, acceptance and final value after the 1 November target
