Fremont Lake Study

Fremont Lake is the source of Pinedale’s drinking water. During the months of August-September 2018 higher levels of bacteria were detected by the lab that analyzed samples from Fremont Lake twice a week. During that time, no bacteria was detected in the Town’s water system due to the ultraviolet light and chlorine disinfection treatment that we use. There is no public health concern related to these bacteria levels. However, because of the higher levels of bacteria detected in Fremont Lake in 2018, the Environmental Protection Agency (EPA) has mandated that Pinedale perform a watershed study of Fremont Lake. This study will determine sources or potential sources of fecal coliform bacteria contamination in the lake. The Town will then implement steps to prevent these sources of bacteria from having a negative effect on the water quality of Fremont Lake. This watershed study is an important part of our commitment to provide clean and safe drinking water from Fremont Lake to our Town residents for many years to come.
