Lewis Creek Association tests water quality at Lewis Creek swimming holes and other locations each year. Provisional 2014 data results suggest Lewis Creek sites at Rte 7 in Ferrisburgh and Tyler Bridge Road in Monkton are currently unsafe for swimming.
The Tyler Bridge site is now owned by Fish and Wlldlife for public access. Please use caution at this site in particular. The ecoli level on July 2 was 686.67 (very high), while the Rte 7 site was 272.3. Both unsafe at this time. The state standard is 77, and about to become 250.
