DIAMOND LAKE, Ore. -- The Oregon Department of Fish and Wildlife (ODFW) and the U.S. Forest Service continue their partnership to monitor Diamond Lake and educate its users on the perils of invasive fish.

ODFW treated the lake in 2006 to rid it of an estimated 95 million Tui Chub.

Before visiting Diamond Lake, they ask that boaters and anglers drain, clean and dry their gear.

This includes  boats, live wells, trailers and anything that has been in the water, and then repeat that process before putting it in another lake.

The Forest Service and ODFW are stepping up efforts this year to keep dirty boats or boats with illegal live bait fish from entering Diamond Lake.

Weekday mornings, ODFW employees will be at Diamond Lake boat ramps to survey boaters and ensure their boats do not have live bait fish and/or aquatic weeds.

Umpqua National Forest staff and an ODFW creel surveyor will cover the boat ramps and surveys on weekends.

Using live bait fish is illegal in Oregon's fresh waters, and the Oregon State Police are increasing patrols this summer.

The ODFW found Golden Shiners in Diamond Lake last year and removed more than 600 through electro-fishing.

Biologists are trying to get an early start to the Golden Shiner removal program that will continue through early August, trying to catch as many as possible.
