Heavy snowstorms and cooler temperatures helped boost Colorado's statewide snow-pack to 74 percent of average in March. According to the Natural Resources Conservation Service, Colorado's snow-pack increased 1 percentage point from March 1st to April 1st. That marks the third consecutive month that Colorado's snow-pack jumped by a percentage point. While there is little chance of reaching normal levels this season, snow-pack in most areas hasn't begun melting yet and in many areas continues to gather snow. Typically, snow-pack peaks and begins melting around April 8th.
