The past two weeks have been unusually dry across most of Iowa. The statewide average precipitation was 0.19 inches, while normal for the period is 1.01 inches. Salem in Henry County in southeast Iowa was one exception, receiving over an inch during this period.
About seven percent of the state remains in severe drought, while about half of the state is rated in moderate drought. This is reflected in the drop of average stream flow in Iowa. Recent rains are reflected in the stream flow index upturn for the past few days.
South of Interstate 80, ice is almost completely gone from rivers. Iowa DNR fisheries biologists continue to monitor oxygen levels in many waters and have seen some slight improvements in some places. Considerable areas of ice remain in northern Iowa.
