Toxic algae blooms are becoming increasingly common in Colorado lakes. In fact, eight lakes are currently suspected of having harmful algal blooms (HABs). These blooms can produce toxins that can cause health problems in people and animals, including skin rashes, gastrointestinal problems, and respiratory issues.
There are a number of factors that are contributing to the rise of HABs in Colorado lakes. These include:
* Increased nutrient pollution: Nutrient pollution from sources such as fertilizers and sewage can feed algae growth.
* Warmer temperatures: Warmer temperatures create ideal conditions for algae to grow.
* Drought: Drought conditions can concentrate nutrients in lakes, making them more susceptible to HABs.
* Climate change: Climate change is expected to lead to more frequent and severe HABs.
The Colorado Department of Public Health and Environment (CDPHE) is working to address the issue of HABs. The department is monitoring lakes for HABs, issuing health advisories when blooms are present, and working to reduce nutrient pollution.
Here are some things you can do to help reduce the risk of HABs:
* Reduce your nutrient footprint: Use fertilizers sparingly, compost food waste, and properly dispose of sewage.
* Be aware of the risks of HABs: Avoid contact with water that has a bloom, and do not eat fish from lakes with blooms.
* Report HABs: If you see a HAB, report it to the CDPHE.
By taking these steps, we can help protect Colorado lakes from the harmful effects of HABs.
Here is a table of the eight Colorado lakes that are currently suspected of having toxic algae blooms:
| Lake | County | Suspected Bloom Type |
|---|---|---|
| Blue Mesa Reservoir | Gunnison, Montrose | Cyanobacteria |
| Grand Lake | Grand | Cyanobacteria |
| Green Mountain Reservoir | Summit | Cyanobacteria |
| Lake Dillon | Summit | Cyanobacteria |
| Lake Granby | Grand | Cyanobacteria |
| Lake Pueblo | Pueblo | Cyanobacteria |
| Lone Tree Reservoir | Jefferson | Cyanobacteria |
| Williams Fork Reservoir | Grand | Cyanobacteria |
