...Hydrologic Conditions...

Due to the rainfall event described above, parts of Lower Michigan
are experiencing significant flooding.  The primary focus of the
flooding is within the Saginaw River basin on the Tittabawassee
River and its tributaries.  The Chippewa River at Mt.Pleasant
crested this morning at 14.8 feet, which was 1.8 feet above Major
Flood category.  This was the 2nd highest crest on record. Routed
high flows from the Salt, Chippewa, and Pine Rivers combined with
the Tittabawassee produced a Major flood at Midland as well.
Midland is currently at 31.6 feet and expected to crest at 31.7
this afternoon.  The crest expected is 3.7 feet above Major Flood
category and will also be the 2nd highest crest on record.  All of
this routed flow is expected to cause the Saginaw River at Saginaw
to rise above Moderate Flood category and crest around 23.5 feet
morning of June 26th.
