Esther Simplot Park pond No. 1 closed due to discovery of algae bloom
The City of Boise has closed Pond No. 1 at Esther Simplot Park due to the discovery of cyanobacteria or blue-green algae.
The type of algae found may produce toxins under the right conditions. All recreation in the pond is prohibited until further notice.
Pond No. 1 is the larger of the two ponds at Esther Simplot Park and it includes the children’s beach area. Boise Parks and Recreation leaders made the call to close the pond out of an abundance of caution. The health and safety of our citizens is always our top priority, so the pond will remain closed to ensure visitor safety until testing is completed. Signs have been posted at the pond to notify citizens of the closure.
The blue-green algae was detected Thursday, July 19 and measures are being taken to eliminate a potentially harmful bloom. Staff members from the City of Boise’s Public Works Department are working with the Department of Environmental Quality to test and treat the water in Pond No. 1.
The City of Boise diligently monitors water quality at Esther Simplot Pond and Quinn’s Pond to protect public health. City staff will continue to update the public on the situation as it develops.
Blue-green algae that produce toxins are not uncommon in local ponds during the summer heat. This type of algae can be harmful to people and pets. The Boise Parks and Recreation Department asks that visitors continue to obey all posted signs and park rules at Esther Simplot Park and nearby Quinn’s Pond. As a reminder, dogs are no longer allowed at Quinn’s Pond or Esther Simplot Park, including ponds No. 1 and No. 2 and the previously designated dog off-leash area.
At this time, Esther Simplot Park Pond No. 2 and Quinn’s Pond remain open for recreational use.
