The Union Reservoir swimming area will remain closed for Fourth of July weekend because of low water levels and a shortage of lifeguards. The City of Longmont said on Saturday that water levels have risen four feet over the last month, but it is still significantly lower than the typical water level at this time of year. The city does not know when the reservoir will be open for swimming, but said it could be as late as August.
The low water levels are a safety concern because exposed areas contain glass, fishing gear, and other debris. Exposed areas have been cleared of dangerous debris, but it cannot be confirmed that submerged areas of the swimming area are safe. The swimming area was originally expected to open for Memorial Day weekend, but it was announced in mid-May that it would not be opening.
In Saturday's Facebook post, one person asked if refunds would be available for this year’s pass due to the closure. The city said those with questions about potential refunds should contact [email protected] or 303-774-4827. A season pass for one car costs $85 for residents and $200 for non-residents.
The city also announced that the entrance to Union Reservoir will close at noon on Independence Day because it is expected to reach capacity before that time. The recreation department encourages people to go to other city parks after the Union Reservoir entrance closes at noon on Friday.
The City of Longmont also sent a release on July 2 to remind residents to avoid contact with blue-green algae blooms, which could have harmful effects on humans and pets. The city said that the algae, known as cyanobacteria, tends to grow in lakes and ponds. Union Reservoir, according to the city, is the only body of water in Longmont that is regularly tested for blue-green algae.
“This season, the swim beach at Union Reservoir has been closed due to low water levels, not algae,” the city clarified. “Park rangers confirm that no blue-green algae has been reported at Union Reservoir this year.”
