A HORSHAM resident believes more police presence is needed at popular recreational areas to curb anti-social behaviour.
The woman, who wished to remain anonymous, said she witnessed anti-social behaviour at Green Lake near Horsham at the weekend.
The behaviour included a group of people drinking, swearing and throwing cans and bottles into the lake.
She said she was concerned for the safety of people who were skiing and swimming.
"People were at risk of running into cans and bottles, which I could see floating and bobbing about," she said.
"It was nice to see young people having a great time but as the day went on they became drunker.
"The language was disgusting."
She said they were also swimming under the influence of alcohol, putting themselves at risk.
"It was very dangerous," she said.
"I was embarrassed and disgusted it was anti-social and shameful behaviour."
The woman said police needed to monitor the area more closely.
"Police should turn up every now and then to keep an eye on the area," she said.
"Maybe rules of what is and is not acceptable should also be posted.
"It is a beautiful area out there and full of families."
Horsham Sergeant Leanne Rivette said generally people in the Wimmera were well-behaved at recreational areas.
She said the incident seemed to be a one-off occurrence.
"We constantly monitor areas such as Green Lake for any anti-social behaviour," she said.
Sergeant Rivette said anyone who witnessed anti-social behaviour should call Horsham police on 5382 9200.
