Esther Simplot Park Pond No. 2 reopened
The City of Boise has reopened Pond No. 2 at Esther Simplot Park.
Quantitative tests show levels of algae species that can be toxic are well below Idaho health advisory levels. Cyanotoxins, while only found in low concentrations during the closure, are no longer present in the water.
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.
Algae blooms can be harmful to people and pets, but it is not uncommon for such conditions to develop in local ponds during the summer heat. The health and safety of our citizens is always our top priority so the pond was closed to ensure visitor safety. The City of Boise diligently monitors water quality at Esther Simplot Pond and Quinn’s Pond.
City of Boise staff were able to take measures to eliminate the potentially harmful algae blooms at Esther Simplot Park Pond No. 2 with chemical treatment because they were found early.
City staff members are also working on a long-term management plan to mitigate E. coli and future harmful algal blooms in the ponds.
Although Pond No. 2 is reopened for recreation, 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 in the ponds and the previously designated dog off-leash area.
