SUMMARY:  Rainfall through January 2018 totaled 3.95 inches and brings the cumulative rainfall total for WY 2018 to 4.97 inches, which is 45% of the long-term average through January.

 

Estimated unimpaired runoff during January totaled 2,640 acre-feet (AF) and brings the cumulative runoff total for WY 2018 to 5,235 AF, which is 27% of the long-term average through January.

 

Usable storage for the MRWPRS was 28,800 acre-feet, which is 96% of average through January, and equates to 77% percent of system capacity.

 

However, through February 13, 2018 rainfall for the month was 0.03 inches.  The remaining forecast for February does not include rain until possibly the last 2-3 days of the month.  If no additional rain is received, the total year-to-date will be similar to 1924, the lowest rainfall total on record.

 

Staff will provide updated information at the meeting to discuss how Water Year 2018 compares to the historical record.
