A May 16 press release from Pagosa Area Water and Sanitation District (PAWSD) District Manager Justin Ramsey urges residents to reduce water consumption due to worsening drought conditions.

It states, “The NRCS SnoTel station reached a Snow Water Equivalency (SWE) of 0” on May 10th a full three weeks quicker than the median. The median date for reaching a SWE of 0” is May 31st.

“Per the Districts Drought Management Plan we would have triggered the Voluntary Drought Stage had the SWE occurred 2 days earlier on the 8th of May.

“Although we are not in a Voluntary Drought Stage, the unseasonably high temperatures and winds will make for a high water use season. Our weekly water use has increased by 2 million gallons over last years weekly usage.

“The District is requesting everyone conserve water and use outside irrigation sparingly. Please do not water between 9:00 am and 6:00 pm. Watering during the hottest part of the day wastes water as a significant portion of the irrigation water evaporates prior to percolating into the soil, wasting not only water but your money.

Drought outlook

Stream flow for the San Juan River on May 18 at approximately 9 a.m. was 1,120 cubic feet per second (cfs), according to the U.S. Geologi- cal Service (USGS) National Water Dashboard, down from a nighttime peak of 1,320 cfs at 2 a.m.

These numbers are down from May 11, when the river flow was at 1,390 cfs at 9:15 a.m. with a nighttime peak of 1,830 cfs at 12:15 a.m.
As referenced in Ramsey’s press release, the U.S. Department of Agriculture (USDA) National Water and Climate Center’s snowpack report at the Wolf Creek summit, at 11,000 feet of elevation, had zero inches of snow water equivalent as of 11 a.m. on Wednesday, May 18. The report also notes that the San Miguel, Dolores, Animas and San Juan river basins were at 4 percent of the May 18 median in terms of snowpack.
