"Well, there is a lot of drinking going on," said Lester Gilpatrick. "There are young kids and stuff partying."

Local law enforcement are aware of the problem - and said summer is the worst time of year at the reservoir.
"Underage parties pick up during the summer months," said Dwes Hutson with the Douglas County Sheriff's Office. "We start to see them increase in frequency."
Gilpatrick said the parties don't just happen at Ben Irving, and it's not just the younger folks who litter.

Hutson encouraged citizens to call the sheriff's office if they see a party going on at night at Ben Irving Reservoir.
