DICKINSON, N.D. - Earlier this summer, the North Dakota Department of Health posted a blue-green algae warning at Dickinson's Patterson Lake.
As the summer comes to a close, the lake may be safe enough to enter again.
The lake passed a water quality test earlier this week - the first test passed since before the Fourth of July. The lake must pass two more tests before the warning can be removed.
"We will be able to move forward. But, again, knowing the weather and the seasons, I really doubt the lake is going to see much activity. We're planning and gearing up towards summer 2017 and hoping everything is cleaned up and clear," says James Kramer, Dickinson Parks and Rec Director.
Kramer says the department has been doing weekly tests since July.
