The National Park Service will increase its environmental patrols at Glen Canyon National Recreation Area, park superintendent John O. Lancaster said Friday.

The park covers 1.2 million acres in southeastern Utah and northwestern Arizona, and Lancaster said officials can use public assistance to prevent environmental damage.Recently a Colorado boater was cited for dumping his outboard motor oil on a beach at Stanton Creek near the Bullfrog Marina on the Utah portion of the lake.

Under federal and state regulations, no article, waste liquid, hazardous material or debris can be dumped into any waterway or on any public land, Lancaster said.

"We need everyone's cooperation and understanding," Lancaster said.
