Denver (AP) - Colorado's snowpack has fallen below average despite a series of spring snow storms.
Snowpack in the state's seven major river basins was at 120 percent of the historic average on Jan. 1, but dropped to 96 percent of average on April 1 after warm, dry weather.
Mike Gillespie of the Federal Natural Resources Conservation Service says that's the lowest percentage recorded all seasons.
The level was at 104 percent today, following another storm.
The snowpack percentage is measured against a 30-year average.
Melting snow contributes about 80 percent of the water in rivers, streams, lakes and reservoirs, which comprise much of the state's water supply.
Denver water managers say reservoirs the city draws on are in good shape.
