Recent water quality test results show rising levels of E. coli bacteria at Esther Simplot Park Pond 1 (where the children’s beach is located) and along the beach at Quinn’s Pond (the side of the pond closest to Esther Simplot Park).
Signs are posted at both beaches warning users to swim at their own risk.
At this time, E. coli bacteria levels are higher than state levels for recreational swim beaches and the city is encouraging users to swim in other areas until tests show levels have come down.
The test results follow days of high use at the ponds and triple-digit temperatures in the Treasure Valley. The city will continue to treat areas of the ponds that have high levels of bacteria in the coming days.
The City of Boise has invested in a variety of upgrades aimed at improving water quality in Esther Simplot Park and Quinn’s Pond, especially during peak season. These changes made in recent years include installation of underwater aerators to aid in water circulation, and a pilot project that introduced river water directly into the ponds.
These latest improvement projects are in addition to geese management plans, dog restrictions, public education, and the addition of new bathroom facilities on site.
