STREAMFLOW FORECASTS FOR NORTH CENTRAL AND NORTHEAST COLORADO AS OF 
APRIL 2015.

MARCH IS TRADITIONALLY THE SNOWIEST MONTH OF THE YEAR FOR MANY 
MOUNTAIN LOCATIONS. HOWEVER...MOUNTAIN SNOWPACK HAS HELD STEADY OR 
DECLINED DURING THE PAST MONTH. BASIN SNOWPACK WAS 84 PERCENT OF 
NORMAL IN THE SOUTH PLATTE BASIN...71 PERCENT OF NORMAL IN THE NORTH 
PLATTE BASIN AND ONLY 68 PERCENT OF NORMAL IN THE UPPER COLORADO 
RIVER BASIN ON APRIL 8TH. SUB-BASIN SNOWPACK ON APRIL 1ST RANGED 
FROM 71 PERCENT OF NORMAL IN THE WILLOW CREEK BASIN IN GRAND COUNTY 
TO 98 PERCENT OF AVERAGE IN THE BLUE RIVER BASIN IN SUMMIT COUNTY 
WEST OF THE CONTINENTAL DIVIDE. HISTORICALLY NORTH CENTRAL COLORADO 
HAS ACCUMULATED OVER 90 PERCENT OF ITS SNOWPACK BY THE SECOND WEEK 
OF APRIL.

RESERVOIR STORAGE REMAINS ABOVE AVERAGE. COMBINED STORAGE WAS 114 
PERCENT OF AVERAGE IN THE SOUTH PLATTE BASIN AND 124 PERCENT OF 
AVERAGE IN THE UPPER COLORADO RIVER BASIN AT THE END OF MARCH. 
STORAGE WAS 91 PERCENT OF CAPACITY IN THE SOUTH PLATTE BASIN AND 78 
PERCENT OF CAPACITY IN THE UPPER COLORADO RIVER BASIN. 

MANY STREAMS ARE RUNNING ABOVE AVERAGE DESPITE THE STAGNANT MOUNTAIN 
SNOWPACK CONDITIONS. THIS IS DUE TO EARLY SNOWPACK MELT AND RUNOFF 
AS ABOVE AVERAGE TEMPERATURES PERSIST. WITH THE LACK OF 
PRECIPITATION THIS SPRING AND THE EARLY MELTOUT...APRIL THROUGH JULY 
STREAMFLOW FORECASTS ARE BELOW TO NEAR AVERAGE. THE NORTH PLATTE 
RIVER NEAR NORTHGATE IS FORECAST TO HAVE ONLY HALF ITS AVERAGE 
STREAM VOLUMES THIS SPRING AND SUMMER. IN CONTRAST...THE BLUE RIVER 
IS EXPECTED TO SEE AVERAGE VOLUMES.
