DENVER (AP) -- The Colorado Lottery says last week's huge Powerball jackpot helped it record its best week ever for sales.

An average week for the Colorado Lottery is about $10 million in sales. The agency says it had sales of $22 million last week, when the Powerball jackpot was $588 million.

The agency reports the figure includes $12.63 million from Powerball sales in Colorado last week, including almost $8.4 million in sales just on Wednesday, when the Powerball drawing was held. That's several times the average weekly Powerball sales in Colorado of about $1.5 million.

Colorado uses lottery proceeds to help fund new trails, as well as open space and wildlife protection.
