Updated forecast on Gavin's releases - river now closed upstream of Glasgow

Two little pieces of just released news, and some more details on levees and the threat to US65:

1. The Corps has released more details on their forecast for Gavin's Point releases. On July 30, releases will be reduced from 160,000 cfs to 155,000. On August 1, they will be reduced to 150,000. Heavy rains could still affect this forecast.

2. The Coast Guard has extended the closure of the Missouri River to all traffic from the Gavin's Point Dam to the Glasgow bridge at river mile 226.3.

3. Snowpack continues to melt. Here's the latest: The snow above Fort Peck peaked at 141% of normal and is now down to 6% of normal.  The snow in the reach between Fort Peck and Garrison (primarily the Yellowstone basin) peaked at 136% and is now down to 4%. The snow in the North Plate basin pecked at 150% of Normal and is currently down to less than 10% and the snow pack in the South Platte Basin peaked at 150% of Normal and the melting in this reach is complete.

4. From Tom Waters of the Missouri Levee & Drainage District Assoc.: The Root Levee breached early this morning.  This levee is located in Southern Carroll County in Missouri.  The breach is 250-33 feet long.  The levee is part of a system of levees, which includes the following levees:  Wakenda Levee, Sambo Slough Levee, and the Farmers Levee.  Combined this system protects around 22,000 acres and US Highway 65 south of Carrollton, Missouri.



MODOT is watching US 65 in Carroll County very closely.  Levee problems in that area may eventually close this highway and the bridge between Carrollton and Waverly.  Current US 65 has one lane open.  9,000 feet of large sand bags have been placed along the highway to try to keep it open.
