Hordemann Pond at Kiwanis Park Temporarily Closed Due to Algae Bloom

The City of Moscow closed Hordemann Pond at Kiwanis Park on August 4, 2025, due to the detection of harmful cyanobacteria in the water. As a precaution, all recreational activities, including fishing, are suspended until further notice. Health officials emphasize that children and pets are especially at risk from toxins that may cause a range of symptoms, including abdominal pain and respiratory issues. The algae bloom is evident in the pond's unusually green water and thick mats along the shoreline. Blue-green algae naturally occur in many Idaho water bodies, and harmful blooms can develop during warm summer months when conditions are favorable.

The city commits to ongoing monitoring of water quality to ensure public safety. David Schott, Parks and Facilities Manager, can be contacted for further information. The city's proactive measures aim to protect community health during this environmental incident.
