Recent heavy rains in Iowa have led to record nitrate levels in the state’s major rivers, prompting concerns over water safety and environmental impacts.

Jared Strong reports for Iowa Capital Dispatch.

In short:

• Record-high nitrate levels have been detected in the Boone, Cedar, Iowa, and Turkey rivers due to recent heavy rainfall.
• Des Moines Water Works has reactivated its nitrate removal system as nitrate concentrations in some rivers exceeded safe drinking water standards.
• State efforts to reduce river nitrate levels through voluntary conservation measures have shown little progress over the past decade.

Key quote:

“This is one of the biggest nitrate leaching events in 11 years.”

— David Cwiertny, director of the Center for Health Effects of Environmental Contamination at the University of Iowa

Why this matters:

High nitrate levels can lead to increased algae growth in rivers and lakes, reducing oxygen levels and harming aquatic life. These conditions can also pose a threat to public health, as they compromise the safety of drinking water sources, particularly in heavily impacted areas like Des Moines.

Iowa women’s basketball head coach Lisa Bluder announced her retirement on Monday as former Hawkeyes star Caitlin Clark nears her pro debut with the WNBA’s Indiana Fever.

Bluder’s longtime assistant Jan Jensen was named her successor.

“There is no denying that this past season was incredible for so many reasons, and we could not have accomplished our achievements without all of you,” Bluder said in an open letter to fans. “After the season ended, I spent time with our student-athletes and coaches reviewing the season and preparing those moving on for what comes next.

“With that also came personal contemplation about what this journey has meant to me, how to best champion this program, and what the future looks like for my family and me. After then taking some time away with my husband, David, it became clear to me that I am ready to step aside.”

Bluder’s retirement came more than a month after Iowa dropped its second consecutive national championship — this time it was to South Carolina.

She spent 24 years leading the Hawkeyes after spending 10 years at Drake. Bluder was 716-359 in her career.

Clark, arguably the best player in Bluder’s tenure, congratulated her former coach.

“Simply no one better at building a team,” Clark wrote on X. “Thank you for believing in me more than anyone. Enjoy retirement, coach. Very much deserved.”

Jensen will take the reins starting in the 2024-25 season. She was an associate head coach under Bluder for 20 years. She was also with Bluder when they were at Drake.

She was an All-American at Drake and the highest-scoring player ever in six-on-six basketball at El Horn-Kimballton High School in Iowa.

“There is no better person to lead this program than Jan Jensen and I am thrilled she will have the opportunity to build on the foundation established,” Bluder said. “I’m committed to help her, and her staff, in whatever capacity they need moving forward.”

(AP) – Lisa Bluder, who coached the Iowa women’s basketball team to the last two NCAA championship games, is retiring after 24 years leading the Hawkeyes.

Bluder made the announcement Monday, five weeks after Iowa lost to South Carolina in the national title game and superstar Caitlin Clark ended her college career.

“There is no denying that this past season was incredible for so many reasons, and we could not have accomplished our achievements without all of you,” she said. “After the season ended, I spent time with our student-athletes and coaches reviewing the season and preparing those moving on for what comes next.

“With that also came personal contemplation about what this journey has meant to me, how to best champion this program, and what the future looks like for my family and me. After then taking some time away with my husband, David, it became clear to me that I am ready to step aside.”

Bluder was 528-254 at Iowa, including 65-12 the past two years with Clark leading the way, and 716-359 including her 10 seasons at Drake.
