Beaches and Water Quality in Grand Rapids, Michigan

Grand Rapids residents enjoy easy access to West Michigan’s lakes and rivers, including popular spots along the Grand River, Reeds Lake, Lake Michigan beaches (like Grand Haven, Holland, and Muskegon), and smaller inland lakes throughout Kent County. While these waterways are great for swimming and recreation, water quality can change quickly—especially with Michigan’s heavy rains, snowmelt, and seasonal weather.

Understanding local beach and water quality in and around Grand Rapids can help you and your family stay safe and healthy.


Recognizing Poor Water Quality

Natural water quality in rivers, lakes, and beaches near Grand Rapids can vary from day to day. Before you or your children swim, look for signs that the water may be unsafe:

  • Water that is discolored (brown, green, or unusually cloudy)
  • Murky water where you cannot see your feet in shallow areas
  • Strong or unpleasant odors
  • Visible scum, foam, or oily sheen on the surface
  • Large amounts of trash or debris in the water
  • Dead fish or other dead/sick wildlife near the shoreline

If you notice any of these signs at a Grand Rapids–area beach, river access, or lake, it’s safest not to swim.


Who Is at Higher Risk?

Some people are more likely to get sick from swimming in contaminated water:

  • Young children
  • Older adults
  • Pregnant people
  • Anyone with a weakened immune system (for example, due to cancer treatment, diabetes, or chronic illness)

These groups should be especially cautious about swimming in natural waters around West Michigan, including the Grand River, Thornapple River, and Lake Michigan beaches.

If you or a family member receives care from Spectrum Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health and have questions about your risk, ask your healthcare provider before swimming in natural water.


Basic Hygiene and Safety at the Beach

Good hygiene helps protect both your health and local water quality.

Use Restrooms and Take Breaks

When visiting Lake Michigan beaches from Grand Rapids or local inland lakes:

  • Use nearby toilet facilities instead of the water
  • Take children on regular bathroom breaks
  • Change diapers in restrooms or designated changing areas, not on the sand
  • Wash or sanitize hands after using the restroom and before eating

Stay Out of the Water if You’re Sick

Do not swim if you:

  • Have diarrhea
  • Are vomiting
  • Have had diarrhea in the last 24 hours

Swimming while sick can spread germs like norovirus, E. coli, and other pathogens into the water, increasing the risk of illness for others.


Open Wounds, Infections, and Stagnant Water

If you have:

  • An open cut or wound
  • A skin infection
  • Recent surgery or a healing incision

you should avoid swimming in natural waters, especially:

  • Warm, shallow, or slow-moving water
  • Stagnant areas with little or no flow
  • Areas with visible algae or scum

If you must go in the water, cover minor wounds with a waterproof bandage and wash thoroughly with clean soap and water afterward. If you notice redness, swelling, or pain after swimming, contact your provider or an urgent care clinic in Grand Rapids.


Sick or Dead Fish and Wildlife

Do not swim if you see:

  • Dead fish along the shoreline
  • Birds or other animals that appear sick or dying in or near the water

These can be signs of pollution, low oxygen levels, or harmful algal blooms, which can affect human health.

Report unusual wildlife deaths or suspected pollution to the Kent County Health Department or the Michigan Department of Environment, Great Lakes, and Energy (EGLE).


Boating and Waste Disposal

Many Grand Rapids residents boat and fish on the Grand River, nearby lakes, and Lake Michigan. To protect water quality:

  • Never dump sewage or wastewater into the water
  • Use pump-out facilities where available
  • Store trash securely on your boat and dispose of it in proper bins on shore
  • Avoid refueling spills; use absorbent pads and follow marina guidelines

Proper waste disposal helps reduce bacteria, chemicals, and litter in West Michigan waterways.


What Is Microbiological Pollution?

Microbiological pollution happens when harmful microorganisms (pathogens) contaminate water or sand. These can include:

  • Bacteria (such as E. coli)
  • Viruses
  • Parasites

In Michigan, these pathogens can reach rivers, lakes, and beaches through:

  • Sewage spills or overflows
  • Malfunctioning septic systems
  • Animal droppings from pets, livestock, and wildlife
  • Runoff from urban and agricultural areas after rain or snowmelt

When you swim in or accidentally swallow polluted water, you can become ill.


Illnesses From Polluted Water

The most common illness from contaminated water is gastroenteritis (gastro), a short-term infection of the stomach and intestines.

Common Symptoms Include:

  • Fever
  • Nausea
  • Vomiting
  • Diarrhea
  • Stomach cramps or pain
  • Headache
  • Sometimes eye irritation or upper respiratory symptoms (sore throat, cough, congestion)

Most cases are mild and improve on their own with rest and fluids. However, young children, older adults, and people with chronic conditions may become dehydrated quickly and may need care at an urgent care center or emergency department (for example, at Spectrum Health Butterworth Hospital or Trinity Health Grand Rapids).

Seek medical care right away if you notice:

  • Signs of dehydration (dry mouth, dizziness, no tears, very little urine)
  • Blood in stool or vomit
  • High fever
  • Symptoms lasting more than a few days

Stormwater Runoff in Grand Rapids and West Michigan

What Is Stormwater Runoff?

Stormwater runoff is rain or melted snow that does not soak into the ground. Instead, it:

  1. Flows over streets, parking lots, lawns, and farm fields
  2. Picks up pollutants along the way
  3. Enters storm drains and roadside ditches
  4. Flows untreated into rivers, streams, and lakes

In the Grand Rapids area, stormwater can carry:

  • Chemical pollutants: fertilizers, pesticides, detergents, oil, and fuel
  • Litter: cigarette butts, cans, food wrappers, plastic bags, and other trash
  • Natural pollutants: leaves, grass clippings, animal waste

All of this can end up in the Grand River, its tributaries, and nearby inland lakes, and eventually in Lake Michigan.


Swimming After Heavy Rain or Snowmelt

In Michigan, heavy rain and rapid snowmelt can significantly affect water quality.

  • After more than about 10 mm of rain (roughly 0.4 inches), natural swimming spots often become more polluted due to stormwater runoff.
  • As a general guideline for West Michigan:
    • Avoid swimming in coastal waters (Lake Michigan beaches) for about 1 day after heavy rain.
    • Avoid swimming in rivers and inland lakes (including the Grand River and local lakes) for about 3 days after heavy rain.

During spring snowmelt or after major storms, bacteria and pollutants can remain elevated for several days, especially in rivers and smaller lakes.


Sewer and Overflow Considerations

Like many Midwestern cities, Grand Rapids has sewer and storm systems that can be stressed during extreme weather events.

  • The sewer system is designed to handle typical flows, but very heavy or prolonged rain can lead to:
    • Stormwater entering sanitary sewers
    • Occasional overflows or emergency discharges at designated points

These measures are intended to protect homes and critical infrastructure, but they can temporarily affect water quality downstream.

How to Stay Safe

  • Avoid swimming near stormwater outfalls, drainage pipes, or culverts
  • Stay out of the water if you see water actively flowing from a nearby drain into a river or lake
  • Pay attention to local advisories from:
    • Kent County Health Department
    • Grand Rapids Public Health
    • Michigan Department of Health and Human Services (MDHHS)
    • Michigan EGLE

Water Quality Monitoring and Beach Advisories in Michigan

Michigan agencies regularly monitor water quality at many public beaches and recreational waters, including along Lake Michigan and at inland lakes used by Grand Rapids residents.

You can find up-to-date information on:

  • Michigan’s rivers and streams
  • Inland lakes near Grand Rapids
  • Lake Michigan beaches popular with West Michigan residents

by checking:

  • Michigan BeachGuard System (statewide beach monitoring and advisories)
  • EGLE (Environment, Great Lakes, and Energy) water quality reports
  • Kent County Health Department website and social media
  • Local city or township websites for specific lakes and parks

During the warmer months, these resources often provide:

  • Current beach status (open, caution, or closed)
  • Bacteria levels (such as E. coli)
  • Recent test dates
  • Advisories after heavy rain or known sewage spills

Understanding Beach Forecast Categories

While terminology may vary slightly by system, beach water quality in Michigan is often described in three general categories:

  • Good – Water is considered fit for swimming based on recent testing
  • Fair – Water quality is borderline or may be affected by recent rainfall; caution is advised, especially for young children, older adults, and people with weakened immune systems
  • PoorAvoid all contact with the water; do not swim or allow pets to enter

Always follow posted signs and online advisories before swimming at Lake Michigan beaches or inland lakes near Grand Rapids.


Other Water Quality Alerts in Michigan

Water quality alerts can be issued at any time of year, including outside the main swimming season. These may include:

  • Harmful algal blooms (HABs), often called blue-green algae
  • Sewage spills or overflows
  • Chemical contamination events

If a harmful algal bloom is present:

  • Do not swim or wade in areas with thick green scum or paint-like streaks
  • Keep pets out of the water
  • Avoid swallowing any water
  • Rinse off with clean water as soon as possible if you have contact

Information about harmful algal blooms and other alerts is available through EGLE, MDHHS, and local health departments.


Seasonal Considerations in Grand Rapids and West Michigan

Michigan’s climate affects water quality and safety:

  • Spring: Snowmelt and spring rains can increase runoff and bacteria levels in rivers and lakes.
  • Summer: Warmer water temperatures can encourage bacterial growth and harmful algal blooms, especially in shallow or stagnant areas.
  • Fall: Heavy autumn rains and leaf litter contribute to nutrient loads and runoff.
  • Winter: While swimming is uncommon, ice safety and contamination from road salt and winter runoff can affect water quality.

Even when you’re not swimming, protecting water quality helps preserve safe drinking water sources and healthy ecosystems in the Grand Rapids area.


How Grand Rapids Residents Can Help Protect Water Quality

You can help improve water quality at local beaches, rivers, and lakes by:

  • Picking up pet waste and disposing of it in the trash
  • Reducing fertilizer and pesticide use on lawns and gardens
  • Keeping leaves and grass clippings out of streets and storm drains
  • Properly maintaining septic systems (if you live outside city sewer areas)
  • Disposing of chemicals, oil, and medications at approved collection sites
  • Participating in local river or beach cleanup events

Local organizations, along with Grand Rapids Public Health and the Kent County Health Department, often sponsor cleanup and education programs focused on the Grand River and nearby lakes.


When to Seek Medical Care

If you become ill after swimming or boating in natural water near Grand Rapids:

  • Monitor for symptoms such as:
    • Fever
    • Vomiting or diarrhea
    • Stomach pain
    • Rash, eye irritation, or breathing problems

Contact your primary care provider or an urgent care clinic (Spectrum Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health) if:

  • Symptoms are severe or last more than a couple of days
  • A child, older adult, or person with a chronic illness is affected
  • You suspect exposure to sewage or a harmful algal bloom

In an emergency—such as trouble breathing, confusion, or signs of severe dehydration—call 911 or go to the nearest emergency department.
