The projects are located on the Red River in Red River and Bossier parishes, Louisiana. The projects occupy Federal lands administered by the U.S. Army Corps of Engineers. At Lock & Dam #4, the unconstructed projects would be redesigned from one turbine that would produce 28.1 megawatts (MW) generating capacity to five smaller turbine units that would still have the same generating capacity of 28.1 MW. The powerhouse would be redesigned to hold the five Kaplan bulb turbine-generator units, and would be approximately 170-feet-wide, 135-feet-high, and 180-feet-long. The headrace channel and tailrace channels would also be redesigned from what was originally licensed. A Notice of Application Accepted for Filing and Soliciting Comments, Motions to Intervene, and Protest was issued on September 12, 2024. At Lock & Dam #5, the unconstructed project would be similarly redesigned with five Kaplan bulb turbine-generator units, instead of one 28.1-MW unit. The powerhouse footprint would be approximately 204-feet-long by 153-feet-wide. The location of the recreation facilities, that the licensee is required to reconstruct, would be relocated from downstream to upstream of the dam. A Notice of Application Accepted for Filing and Soliciting Comments, Motions to Intervene, and Protest was issued on September 30, 2024.
