Rivers. — The ice in the Mississippi River broke up and moved out at 

 Muscatine and Davenport on the 11th; LeClaire on the 19th; Clinton on 

 the 21st; and Dubuque on the 22nd. The stages were moderate. The 

 smaller rivers broke up quietly about the middle of the month in the 

 southern half of the state where very little precipitation had accumulated 

 during the winter. Further north the breakup was caused by a rather 

 sudden change to warmer weather on the 19th, acting upon more than a 

 normal accumulation of snow and ice. The Cedar River at Cedar Rap- 

 ids passed the flood stage of 14 feet during the night of the 25th-26th, 

 reaching a crest stage of 17.3 feet at 6 p. m. of the 26th. The Des Moines 

 River at Boone, passed the flood stage of 17 feet on the 23rd, reaching a 

 crest stage of 20 feet on the 25th. Several small rivers in northern 

 Iowa, gorged, overflowed, washed out bridges and culverts, and seriously 

 delayed railway and other traffic. This was the only damage reported.
