This summer the algae is gone which has business owners optimistic.
Last summer was a difficult one for many grand lake business owners. But, they are optimistic this year will be better.
"July was a very bad month," says Dick Ranes.
Ranes has owned Lee's Resort on Grand Lake for 30 years.
He says last year's blue green algae outbreak drove away many of his visitors.
"Last year was almost devastating to our business," says Ranes.
But this year, Ranes' already seeing a brighter future.
In fact, the cabins on his property are completely booked through August.
"So far our 2012 is ahead of last year, well ahead, over 20% ahead," says Ranes.
Back on the main land, shop owner Sam Williams is also optimistic.
"The 5 and half years I've been here this is the best I've ever seen for the start of the year," says Williams.
Williams says Memorial Day weekend has kept him extremely busy, a good change from last year.
"Fantastic. That's all I can say. This is when we make it. We need good summers," says Williams.
