| 摘要： | The St. Louis Engineer Districts Jerry F. Costello Lock was closed to traffic August 19 when it could no longer close its downstream miter gates due to silt and debris build up in the lock sill and chamber, the St. Louis District announced. Contracted divers were deployed to remove underwater obstructions, but the issue with the gate persisted. Crews from the St. Louis District's Motor Vessel Pathfinder were on site August 23 to excavate silt that was pre- venting the gates from properly closing. The Jerry F. Costello Lock (formerly the Kaskaskia Lock and Dam) is the only lock and dam on the Kaskaskia River, located at its mouth at the confluence with the Mississippi River at Mile 117. |
