The Health Department actively monitors and assesses the water quality at Centennial Beach in accordance with the State Sanitary Code, Chapter VII.  We conduct weekly inspection of the beach, and collect water to test for E. coli bacteria.  Inspection and testing results for 2015 are posted below.  Contact us for results of prior years.

We also monitor cyanobacteria (blue green algae) activity in various lakes and ponds in Hudson, especially Fort Meadow Reservoir and Lake Boon.  Please contact us if you are seeing blooms like the pictures below, please contact our office.
