(Radio Iowa) – A University of Iowa environmental engineering professor says it will take ten BILLION dollars to address the state’s water quality issues and reduce the likelihood of flooding. Larry Weber conducts research on flooding AND water quality. “If we could spend $200 million a year and divide $200 million into $10 billion, that’s 50 years,” Weber says. “So like we’ve changed the way soil comes off the land in the last 50 years, we could change the way water and nutrients come off the land in 50 years, but we need the political will to do it.”

Weber says the 2023 Farm Bill could include rules to reduce farm run-off that would apply not just to Iowa farmers, but to all U-S ag operations. “We’ve had a lot of talk,” Weber says. “The talk has been going on now for a decade or more and we’re just simply not making the progress that Iowans should expect to receive.”

Weber says the drought in much of Iowa will have an impact on water quality, too, since corn and soybean plants in dry soil are not absorbing as much of the commercial fertilizer and manure that’s been applied to fields. “When we do get rain and the water starts to flow and our tiles flow again, we will likely see a real large movement of nitrates coming out of our farm system,” Weber says.

Some Iowa utilities that provide drinking water use surface water from rivers, but about 75 percent of Iowans get their drinking water from underground supplies. “That water has taken tens of thousands and in some cases millions of years to accumulate in those deep aquifers, but it too will be stressed,” Weber says. “Those resources, although ample today, will not be endless. We will have to start thinking about what we will do at the end of the turn of the century, especially as these floods and droughts become more prevalent in our state.”

Weber made his comments this weekend on “Iowa Press” on Iowa P-B-S.

(Radio Iowa) – The new map from the U-S Drought Monitor shows worsening conditions across Iowa. Only five percent of the state is shown as having normal conditions, all in the southeast, while drought gained more ground practically everywhere else. Parts of eastern and far southwestern Iowa are in the abnormally dry category, but the majority of the state’s in drought.

A week ago, 56-percent of Iowa was in moderate to severe drought, now, it’s 76-percent. Severe drought covers about 40 of the state’s 99 counties, including virtually all of northern Iowa and much of the central region.

A heat advisory is posted for much of the state today (Thursday), as highs are forecast to reach the upper 90s to around 100 degrees, with heat indices in southwest Iowa climbing to 107.

The first severe thunderstorm warnings in June were issued for the KJAN listening area, Wednesday night. The National Weather Service issued a Severe Thunderstorm Watch at around 10-p.m., and less than 30-minutes later issued a Severe Thunderstorm Warning, for Audubon and Guthrie Counties. The Weather Service says at around 10:17-p.m., thunderstorm wind damage was reported in Templeton, where tree branches ranging in size from 2-to 6-inches in diameter were snapped, and a flag pole was blown over.

At around 10:32-p.m., thunderstorm winds knocked a tree and blocking Highway 141, two miles northwest of Manila. A personal weather station six-miles west of Gray recorded a wind gust of 60-miles per hour at around 10:19-p.m. Another personal weather station reported a 62-mile per hour wind gust two miles south of Willey, in Carroll County, and a 59-mile per hour wind gust two miles northwest of Carroll.
