Jerrine Peeler, stated the purpose is to urgently restore the operational depth at the Hoonah Seaplane Float facility to -8' MLLW to prevent the imminent structural failure of the floating infrastructure. PROPOSED WORK: The applicant is proposing to dredge 400 cubic yards of natural sand and gravel from 0.15 acres of tidal waters under and around the existing dock. The dredged material would be placed into 0.15 acres of tidal waters adjacent and along the upper regions of the existing shoreline. The work would be conducted from an excavator on the tidelands during low tidal stages when the site is almost entirely dewatered. It is anticipated that the work would occur over approximately one week of negative tides. All work would be performed in accordance with the enclosed plan (sheets 1-4), dated September 2025.

Walla Walla District Engineers among those recognized for innovative digital design of major navigation system

Elijah Wittum — Fri, 13 Mar 2026 18:57:00 GMT

When a barge passes through a navigation lock along the McClellan-Kerr Arkansas River Navigation System, few people think about the massive steel gates that quietly make the process possible. Behind those gates is a team of engineers and technical specialists from across the U.S. Army Corps of Engineers, including experts from the Walla Walla District, using advanced digital modeling tools to design the next generation of infrastructure that keeps commerce moving along the nation’s inland waterways. Recently, the team’s work was recognized in the agency’s 2025 national awards program. Engineers and technicians supporting the project received the Computer-Aided Design/ Building Information Modeling Team Award of Excellence for their innovative design work supporting the navigation system. Personnel from the Walla Walla, Philadelphia, Mobile, Louisville, Little Rock, Tulsa and Rock Island districts collaborated to design replacement miter gates for 18 locks and dams on the navigation system.

John H. Overton Lock and Dam, Red River: Lower Navigation Approach Physical Model

Press Operations — Fri, 13 Mar 2026 17:42:00 GMT

Abstract: The US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (ERDC-CHL) conducted a physical model study of the John H. Overton Lock and Dam to optimize the navigation conditions in the lower lock approach. ERDC built a 1:100 Froude scale model to evaluate the navigation conditions for tows entering and exiting the lower lock approach. The final design consisted of two submerged rock dikes implemented approximately 1,500 and 3,000 ft downstream of the dam’s crest. The larger submerged rock dike was parallel to the channel, located in a scoured area at the downstream end of the riprap channel bed, and contained a crest elevation of approximately 15 ft, North American Vertical Datum of 1988 (NAVD 88). The smaller submerged rock dike extended from the most upstream end of the first rock dike, diagonally crossing the channel to the right-descending bank, and contained a crest elevation of approximately 30 ft, NAVD 88. The model provided data regarding tow tracks, current direction, and velocity information for various possible optimizations to the dam’s lower lock approach.

U.S. Army Corps of Engineers publishes Finding of No Significant Impact for the Lake Istokpoga Temporary Deviation

Press Operations — Fri, 13 Mar 2026 17:26:00 GMT

(Mar. 13, 2026) – The U.S. Army Corps of Engineers, Jacksonville District (Corps) has prepared a National Environmental Policy Act (NEPA) Environmental Assessment (EA) and proposed Finding of No Significant Impact (FONSI) for the expedited planned, temporary deviation from the 2016 Lake Istokpoga Regulation Schedule. The proposed planned, temporary deviation is being pursued to allow continued water supply releases from Lake Istokpoga when the lake stages drop below the existing Zone B, due to drought conditions observed this dry season, to meet downstream water supply needs within the Indian Prairie Basin, including deliveries to the Seminole Tribe of Florida.
