Swimming in Lake Houston can sometimes pose health risks, as official assessments indicate that its water quality occasionally shows bacterial concentrations exceeding state standards for contact recreation.
While Lake Houston is a popular spot for recreation, visitors should be aware of potential water quality issues. The Texas Commission on Environmental Quality has determined that Lake Houston and several of its tributaries sometimes have bacteria levels that are higher than state standards for contact recreation. This means that engaging in activities like swimming, where there is direct contact with the water, could expose individuals to bacteria that may cause illness.
Understanding Water Quality in Lake Houston
Water quality in natural bodies like Lake Houston can fluctuate due to various factors. Elevated bacteria levels are often linked to stormwater runoff, which can carry pollutants from urban and rural areas into the lake, especially after heavy rainfall. While not always present, the occasional exceedances of state standards for recreational contact warrant caution.
Factors Affecting Swim Safety
Several factors can influence the safety of swimming in Lake Houston:
- Bacteria Levels: The primary concern is the presence of bacteria, which can indicate fecal contamination and the potential for waterborne illnesses.
- Recent Rainfall: Heavy rains can significantly increase runoff, washing more pollutants and bacteria into the lake. It is generally advisable to avoid swimming shortly after a major rain event.
- Location within the Lake: Some areas, particularly near tributary inflows, might have higher concentrations of bacteria than open lake areas.
- Individual Health: People with weakened immune systems, open wounds, or who are very young or elderly may be more susceptible to waterborne illnesses.
How to Stay Safe When Visiting Lake Houston
Even with potential water quality concerns, you can still enjoy Lake Houston by taking precautions:
- Check for Advisories: Before heading out, look for any current water quality advisories or closures issued by local health departments or environmental agencies. While specific real-time bacterial counts might not always be publicly available for every area, general advisories are crucial.
- Avoid Swimming After Rain: Give the lake at least 24-48 hours to flush out after heavy rainfall before swimming.
- Prevent Water Ingestion: Try to avoid swallowing lake water while swimming, as this is a common way to contract waterborne illnesses.
- Shower After Swimming: Rinse off thoroughly with soap and clean water after leaving the lake.
- Protect Open Wounds: Cover any open cuts or scrapes with waterproof bandages to prevent bacteria from entering your bloodstream.
Lake Houston Safety Considerations
Here's a quick overview of key safety considerations:
| Aspect | Safety Consideration |
|---|---|
| Water Quality | Sometimes has bacteria levels exceeding state standards for contact recreation. |
| Post-Rain Swimming | Avoid swimming immediately after heavy rainfall due to increased runoff and potential for higher bacteria. |
| Ingestion Risk | Minimize swallowing lake water. |
| Vulnerable Populations | Individuals with compromised immune systems or open wounds should exercise extra caution. |
| Advisories | Check for local water quality advisories before planning your visit. |
Resources for Current Water Quality Information
For the most up-to-date information regarding Lake Houston's water quality, consult official sources:
