Kansas City: River Operations (update)
Bridge work RM 395.4 - Harry S Truman Railroad Bridge – Starting 15 Aug through 19 Aug bridge maintenance will be underway. The maintenance will close the river channel from 0500 to 1000 each day.
Missouri Reservoirs – July 1 system check - Gavins Point Dam releases will be set to provide navigation flow support at a level 500 cfs above minimum-service at all four target locations (Sioux City, Omaha, Nebraska City, and Kansas City). Flow targets may be missed to conserve water if there is no commercial navigation in a given reach. The navigation flow support season will be 3 days less than the normal 8-month season.
River forecast – Rain is returning to forecast. With Missouri forecast to see between 1 – 3 inches over next 3 days. Impact on river levels will depend on how fast rain falls. Dry conditions will minimize runoff and impact to river levels. Approximate flows downstream of KC are;
KC – 36 kcfs
Waverly – 35.7 kcfs
Glasgow – 34.5 kcfs
Boonville – 39.5 kcfs
Hermann – 41.3 kcfs
