SUMMARY-MARCH 2003

Streamflows were in the normal range for most of Maine except for the St John River basin which was in the below-normal range.

Ground-water levels covered all the ranges with five of the ten index wells in the above-normal range, two in the normal range and three of the ten in the below-normal range.

The total amount of water in usable storage in the five reporting basins at the end of March was 34 percent of capacity, which is below the long-term end-of-March average of 40 percent.

March precipitation, at 16 stations, averaged 104 percent of normal.








STREAMFLOW:

Runoff was in the normal range in March except for the St. John River basin which was in the below-normal range. The following table lists March runoff at seven index gaging stations.

Total quantity of water in usable storage increased by 1,810 million cubic feet (mcf) and at the end of the month was 56,692 mcf. The following table shows conditions in the five reporting systems at the end of March, as reported by the river basin managers, expressed in percent of reservoir capacity.

GROUND-WATER:

Ground-water levels were in the below-normal, normal and above-normal ranges.  Water levels in five of the ten wells were in the above-normal range. Water levels in nine of the wells had increased when compared to water levels at the end of March 2002.
