Pond No. 2 at Esther Simplot Park in Boise closed due to algae

The City of Boise has closed one of the ponds at Esther Simplot Park because of a positive test for algae that could be deadly if ingested.

The pond shut down is Pond No. 2 and is the smaller pond to the west of the main pond.  It has no beach area and the city says it doesn't get as much recreational use as the bigger pond.

The city says while that algae can be dangerous to people and pets it is common for this kind of condition to occur in ponds during the summer.

Signs will warn people to stay away from the pond and keep children and pets out of the water as well.  The city also wants to remind people dogs are not allowed in any of the ponds at Esther Simplot Park.

The city has these tips to stay safe while the algae is present:

  • No wading
  • No swimming
  • No consumption
  • Do not let your pets drink from the pond
  • Obey all posted signage

City officials say they will use a chemical treatment to get rid of the algae and will provide updates on pond closures at the Boise Parks and Recreation website.
