Please be aware if you all are going out and about to squeeze in some late summer lake fun.
INITIAL TEST RESULTS SHOW HIGH LEVELS OF E.COLI IN RIVER - The Colorado Department of Public Health and Environment said testing revealed high levels of E.coli downstream from a sewage discharge in Pueblo.
The City of Pueblo reported that over 4 million gallons of untreated sewage was leaked into the Arkansas River, caused by a faulty patch to a sewer line.
The spill happened Wednesday morning but wasn’t discovered until Thursday.
The leak was fixed Thursday, but CDPHE is asking the public downstream from the Confluence Lake to avoid water recreation for the time being.
The advisory applies to the Arkansas River from where Fountain Creek enters the river through John Martin Reservoir.
The following areas should avoid the water until Monday, August 31 (however we researched the subject and the long term effects of such contamination, as linked below):
Avondale, Boone, Fowler, Manzanola, Rocky Ford, Swink, La Junta, Las Animas
The department doesn’t believe this will affect drinking water but officials overseeing farms are worried about irrigation water on growing edibles in Southeast Colorado. All farmers have been notified and water will be monitored.
However in Pueblo County, farmers get their water from the lake via the Bessemer Ditch. At least one farm in the county posted on FB this won’t affect them, but they will still be monitored by state officials to ensure the health of their produce. It’s the communities further downstream from the Arkansas River that may be affected.
