 SAN JUAN RIVER BASIN SPRING FLOOD POTENTIAL OUTLOOK

The 2007 spring runoff flood potential is not high at this time for streams
and rivers throughout the San Juan River Basin. The observed water year
precipitation to date is around 100% of average. Snow water equivalent as of
June 1 was 50% in the Upper San Juan, 30% in the Animas, and 40% for the entire
San Juan Basin.

It is important to note that the spring flood threat due to runoff will largely
be determined by hydrometeorologic events that occur during the next month.

Peak flows for four selected points are as follows:
