CPW warns public to avoid contact with water at Deweese Reservoir due to algae bloom | KRDO

Sustainable Development Goals (SDGs) and Toxic Blue-Green Algae at DeWeese Reservoir State Wildlife Area

Introduction

The DeWeese Reservoir State Wildlife Area in Custer County, Colorado, is currently experiencing a growing bloom of toxic blue-green algae. Colorado Parks and Wildlife (CPW) is warning the public about the potential dangers associated with this algae and urging visitors to avoid contact with the water, including pets.

Health Risks

The toxic blue-green algae present in the reservoir can be harmful to both humans and pets. Contact with the algae can cause skin rashes and, if ingested, it can be potentially fatal. CPW District Wildlife Manager Justin Krall emphasizes the importance of showering immediately with fresh, clean water if anyone or their pet comes into contact with the algae.

Warning Signs

CPW has placed signs at the reservoir to inform visitors about the dangers of the algae and to advise against water contact. These signs also provide instructions on what to do if contact occurs.

Fishing Precautions

The DeWeese Reservoir State Wildlife Area is primarily used by fishermen. While fishing is still allowed during the algae bloom, it is crucial to avoid skin-to-water contact. Additionally, caution should be exercised when handling and cleaning any fish caught in DeWeese, as toxins can accumulate in the liver and guts. Proper cleaning and thorough cooking of the fish are essential before consumption.

Role of Algae and Health Impacts

Algae play a vital role in aquatic food webs. However, certain types of blue-green algae have the ability to produce toxins that can negatively impact human and pet health when present in high concentrations.
