State Health Officials Warn of Toxic Algae in Colorado Reservoirs and Lakes
Denver – The Colorado Department of Health and Environment (CDPHE) is urging Coloradans to be cautious of toxic, blue-green algae while engaging in recreational activities in reservoirs and lakes this summer. The warmer weather has led to the growth of algae blooms, which can be harmful to both humans and pets.
Temporary Closures and Potential Blooms
So far this year, three water sites in Colorado have been temporarily closed due to dangerous concentrations of toxic, blue-green algae blooms. Additionally, eight other sites are awaiting confirmation from a state lab regarding potential blooms in their water.
According to a spokeswoman for Colorado Parks and Wildlife (CPW), swimming, paddleboarding, and wading are currently prohibited near the marina and West Shades area of Cherry Creek Reservoir due to elevated levels of microcystin, an algal toxin. However, boating and fishing are still allowed. Recreation is also currently prohibited at Barr Lake, Dewesee, and Road Canyon reservoirs.
Several other reservoirs across the state, including Jumbo, North Sterling, Jackson, Stagecoach, Beaver Creek, La Jara, and Vega, have reported potential blooms. Blue Haron Lake is awaiting test results for algal toxins.
To check for algae bloom concentrations at any of these sites, visit the CDPHE website and select the “Recent conditions” tab.
Precautions at Vega Reservoir
Visitors to Vega Reservoir in Colorado’s Western Slope are advised to avoid any activities in the water where algae is visible. It is especially important to be mindful when walking pets near the reservoir and prevent them from drinking the water or ingesting dried scum along the shoreline, as blue-green algae can be toxic to pets. If accidental exposure occurs, rinse pets thoroughly with potable water and wear gloves for personal protection if possible.
Health Risks and Symptoms
Blue-green algae, also known as cyanobacteria, can produce toxins that pose health risks to humans and pets at elevated concentrations. If you or your pet comes into contact with a harmful bloom, it is important to take immediate action.
- Rinse your pet off immediately with fresh, clean water if they come into contact with a harmful bloom.
- If you or someone you know comes into contact with the bloom, wash with soap and water immediately.
- If your pet shows symptoms such as diarrhea, vomiting, weakness, drooling, difficulty breathing, or convulsions/seizures after exposure to the water, contact a veterinarian immediately as these toxic algae can be fatal to pets.
- Humans exposed to the algae may experience skin irritation, diarrhea, stomach pain, fever, headache, and sore throat. Exposure to the toxins can also harm the liver, kidneys, and neurological systems.
Mitigating Algae Blooms
While algal blooms are common in the summer when water temperatures rise, there are steps individuals can take to help prevent their occurrence:
- Pick up after your pets and properly dispose of their waste to prevent nutrients from entering waterways, which contribute to algae blooms.
- Refrain from using excessive amounts of fertilizer.
- If using de-icers, ensure they do not contain urea.
