FORSYTH COUNTY -- A total of 30 arrests were made in Forsyth County and on Lake Lanier for driving or boating under the influence during the long Memorial Day weekend, officials said.

Forsyth County Sheriff’s Office deputies made 20 DUI arrests between Friday, May 27 at midnight and Monday, May 30 at 11:59 p.m., according to Deputy Epifanio Rodriguez, a spokesman for the agency.

“That includes on roadways and in the water,” he said.

Deputies also responded to a total of 40 vehicle accidents during that same time period. Four injuries were reported, one of which was deemed serious but non-life threatening.

That crash involved an 80-year-old man from Cumming whose pickup truck was struck by a Chevrolet Cruze on Ga. 400 when he reportedly failed to yield as he made a left turn onto Crossroads Road May 30 about 9:45 p.m.

Rodriguez said the sheriff’s office did not respond to any accidents on the lake.

However, the Georgia Department of Natural Resources, which patrols much of the lake, did.

According to Mark McKinnon, public affairs officer for DNR’s law enforcement division, the state agency recorded 10 BUIs and one boating

incident from 12:01 a.m. on Saturday, May 28 through 11:59 p.m. on Monday, May 30.

The boating incident caused one injury and reportedly involved alcohol. No fatalities were reported.

Last year, McKinnon said, DNR reported 11 BUIs and 6 boating incidents. In 2014, they saw the same number of BUIs and eight boating incidents, compared to 12 BUIs and two boating incidents in 2013.
