PAGE, Ariz. (AP) -- Lake Powell in northern Arizona is steadily rising, opening up access for bigger boats to popular tourist spots in spring.The U.S. Bureau of Reclamation says the water levels are expected to rise one foot per day through June, bringing the lake up to 40 feet higher than its lowest point this year.Lake levels typically drop in the winter and rise again in the spring as melting snow makes its way to the reservoir.Bureau engineer Katrina Grantz says what's considered normal runoff has been scarce since 2000. Even with the steady rise, the lake is well below its 50-year average.The rising waters have expanded passages to Rainbow Bridge in far southern Utah and to Navajo Canyon. Three concrete launch ramps also are open.© 2014 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
