Esther Simplot Park pond No. 2 closed due to harmful algal blooms
The City of Boise today closed Esther Simplot Park Pond No. 2 because water samples have tested positive for algae species known to be toxic and potentially fatal if ingested.
Pond No. 2 is the smaller of the two ponds at Esther Simplot Park. It is located west of the main pond, has no beach area, and sees much less recreational use than the larger pond.
While these algal blooms can be harmful to people and pets, it is not uncommon for such conditions to develop in local ponds during summer heat.
Signs alerting park users to the closure will be posted immediately and park patrons should not swim or wade in the affected pond and should keep all children and pets away from the water. As a reminder, dogs are not allowed in any of the ponds at Esther Simplot Park.
These algal blooms can be harmful to humans and pets, and it’s important that all residents pay close attention to these precautions:
- No wading
- No swimming
- No consumption
- Do not let your pets drink from the pond
- Obey all posted signage
The City of Boise diligently monitors water quality at Esther Simplot Pond and Quinn’s Pond. At this point, there is no reason to close the main pond at the park or nearby Quinn’s Pond. Updates on pond closures will be posted on the Boise Parks and Recreation website.
The algal blooms were detected early, and City of Boise staff are working quickly to eliminate them with chemical treatment. Esther Simplot Pond No. 2 will remain closed until the ponds are cleared of dangerous levels of algae.
