Des Moines, Iowa – The Iowa Department of Natural Resources (DNR) is advising residents to avoid swimming at 19 beaches statewide. This caution stems from concerning levels of E. coli bacteria and the presence of toxic algae. Officials are prioritizing public health and safety with these preventative measures.
The DNR regularly monitors water quality at public beaches throughout Iowa.Recent tests revealed that several locations exceed safe limits for recreational water use. Elevated E. coli levels can cause gastrointestinal illness, while toxic algae pose risks to both humans and animals.
did You Know? E. coli is a type of bacteria commonly found in the intestines of animals and humans. It can contaminate water sources through runoff and sewage.
The affected beaches are located across various regions of Iowa. The DNR has posted warning signs at each location, clearly indicating the risks associated with entering the water. Residents are urged to heed these warnings and seek choice recreational areas.
Pro Tip: Always check local advisories before swimming in natural bodies of water. The DNR website provides up-to-date information on beach conditions.
| Region | Number of Affected Beaches |
|---|---|
| Northwest Iowa | 4 |
| Northeast Iowa | 3 |
| Central Iowa | 6 |
| Southwest iowa | 2 |
| Southeast Iowa | 4 |
The DNR is working to identify the sources of contamination and implement strategies to mitigate the problem. This includes increased monitoring,public education campaigns,and collaboration with local communities.
The agency emphasizes the importance of responsible recreation.Individuals who come into contact with contaminated water should rinse thoroughly with clean water and seek medical attention if they experience any symptoms of illness.

Understanding E. coli and toxic Algae
E. coli bacteria can enter waterways from various sources, including agricultural runoff, sewage overflows, and wildlife waste. Symptoms of E. coli infection include diarrhea, abdominal cramps, nausea, and vomiting. In severe cases, it can led to kidney failure.
Toxic algae, also known as harmful algal blooms (HABs), produce toxins that can cause skin irritation, respiratory problems, and neurological effects. Pets are particularly vulnerable to HABs, as they may ingest contaminated water while swimming.
Frequently Asked Questions About Iowa Beach Warnings
- Q: what causes high E. coli levels in Iowa beaches?
A: High E. coli levels can be caused by agricultural runoff, sewage overflows, and animal waste contaminating the water. - Q: Is it safe to swim if there are no warning signs posted?
A: While generally safer, it’s always best to check the Iowa DNR website for the latest advisories before swimming. - Q: What are the symptoms of E. coli infection?
A: Symptoms of E. coli infection include diarrhea, abdominal cramps, nausea, and vomiting. - Q: How can I protect my pets from toxic algae?
A: Prevent your pets from swimming in or drinking water from areas with visible algae blooms. - Q: Where can I find up-to-date information on Iowa beach conditions?<

Iowa beaches Closed for Swimming: Water Tests Reveal Unsafe Conditions at 19 Locations
As of today, August 10, 2025, a significant number of Iowa’s popular swimming beaches are under advisory or entirely closed due to recent water quality tests. These closures impact recreational activities across the state, prompting concerns for public health and highlighting the importance of regular water monitoring. This article provides a detailed breakdown of the affected areas, the reasons behind the closures, and what you need to know to stay safe.
Current Beach Closures & advisories – August 10, 2025
Nineteen locations across Iowa have reported unsafe water conditions, leading to either full closures or swimming advisories. Hear’s a comprehensive list, current as of 4:04 AM CST:
Black Hawk Lake (Buchanan County): Closed – High E. coli levels detected.
Clear Lake (Cerro gordo County): Advisory – Elevated bacteria counts.
Lake Anita (Cass County): Closed – Harmful algal bloom (HAB) confirmed.
Lake Cascade (Washington County): Advisory – Increased levels of microcystin.
Lake Delhi (Delaware County): Closed – Multiple bacterial exceedances.
lake Manawa (Pottawattamie County): Closed – High levels of E. coli and cyanobacteria.
Lake Panorama (Guthrie County): Advisory – Moderate bacteria levels.
Lake red Rock (Marion County): Closed – Confirmed HAB and bacterial contamination.
Little Sioux Lake (Harrison County): Closed – Significant E. coli spike.
Okoboji Lake (Dickinson County): Advisory – Elevated bacteria, particularly after recent rainfall.
Pikes Peak State Park Beach (Jackson County): Closed – High bacteria counts.
Pleasant Creek State Recreation Area Beach (Franklin County): Advisory – Moderate levels of cyanobacteria.
Rathbun Lake Beach (Appanoose County): Closed – HAB and bacterial concerns.
Saylorville Lake (Polk County) – Jester Park: Closed – High E. coli levels.
Silver lake (Harrison county): Closed – Confirmed HAB.
Storm Lake (Buena Vista County): Advisory – elevated bacteria levels.
Swan Lake (Carroll County): Closed – Significant bacterial contamination.
Union Grove State park Beach (Tama County): advisory – Moderate bacteria levels.
West Okoboji Lake (Dickinson County): Advisory – Elevated bacteria, monitoring ongoing.

Understanding the Risks: Common Contaminants
Several factors contribute to unsafe swimming conditions in Iowa lakes and beaches. Understanding these risks is crucial for protecting yoru health.
E.coli Bacteria: Frequently enough originating from agricultural runoff, sewage overflows, or animal waste, E. coli can cause gastrointestinal illness, including diarrhea, vomiting, and stomach cramps.
Harmful Algal Blooms (HABs): These blooms, fueled by nutrient pollution (nitrogen and phosphorus), produce toxins called cyanotoxins. Exposure can lead to skin irritation, nausea, vomiting, and, in severe cases, liver damage. Iowa’s agricultural landscape, as noted in reports about the state’s economy, contributes to nutrient runoff.
Cyanobacteria (Blue-Green Algae): A type of bacteria that can form HABs. Even without visible blooms, cyanobacteria can release toxins into the water.
Microcystin: A specific cyanotoxin produced by certain types of cyanobacteria. It’s a potent liver toxin.
Agricultural Runoff: Iowa’s extensive agricultural operations contribute significantly to nutrient and bacterial runoff into waterways, especially after heavy rainfall.
What Causes These Water Quality Issues?
Iowa’s geography and agricultural practices play a significant role in these recurring water quality problems.
