LYONS, Colo. (AP) — Some residents in areas devastated by September's floods have new concerns as Colorado's massive snowpack begins to melt.

The Associated Press reports that the state's snowpack, among the highest in 35 years, is poised to melt and sweep across a landscape already damaged by last year's historic floods. Meanwhile, crews hope spring flooding doesn't endanger the millions of dollars in repairs that already have been made.

Still about three weeks from the typical peak of the northern Colorado snowmelt, creeks and rivers are already being tested. Water managers say areas above the flood zones have a snowpack of about 150 percent of its 30-year average, and some areas are closer to 250 percent.

Last year's floods killed nine people and damaged or destroyed nearly 2,000 homes.
