Iowa Ag Connection - 07/12/2019

After higher amounts of rainfall in May, June rainfall in Iowa was 3.86 inches, or more than an inch below normal for the month, according to the latest Water Summary Update. June is typically the wettest month of the year in Iowa.

"While June was drier than normal across the state, the last 12 months are still the second wettest on record," said Tim Hall, DNR's coordinator of hydrology resources.

During the past year, the state has received 15 inches more than its normal 32 inches of rain. The drier than normal June has resulted in some stream flows diminishing, but higher than normal flows continue on the Missouri and Mississippi Rivers.

Iowa temperatures averaged 69.3 degrees, or 0.4 degrees below normal. Spencer Municipal Airport in Clay County reported the month's high temperature of 99 degrees on June 30. The Guttenberg Lock and Dam in Clayton County reported the month's low temperature of 39 degrees on June 13, 21 degrees below average.

Streamflow conditions across the majority of the state remain above normal.
