...Spring Storms Bring Abundant Moisture to Eastern Colorado...

SYNOPSIS...

Late winter and early spring storm systems have provided abundant and
much needed moisture to eastern Colorado. Precipitation through the
middle of May is also proving up to task, thus far, with widespread
2 to 3 inch amounts recorded across southeastern Colorado, along with
pockets of 4 to 6 inches of precipitation recorded across the southeast
mountains.

With that said, the latest US Drought Monitor, issued Thursday May 20th
2021, indicates marked improvement in drought conditions across southeast
Colorado, especially across southwestern portions of Pueblo County and
east central Huerfano County, where the US Drought Monitor has eliminated
any designation of drought.

The latest US Drought Monitor indicates severe drought (D2) conditions
across southeast Colorado now limited to southern portions of Las Animas
County, with severe drought (D2) conditions also persisting across Mineral
County and western portions of Saguache County.

Moderate drought (D1) conditions are now indicated across central into
northeastern portions of El Paso County, central portions of Kiowa
County, northeastern portions of Bent County, northwestern portions of
Prowers County, extreme southeastern Costilla County, central portions
of Las Animas County and extreme southwestern Baca County. Moderate
drought (D1) conditions also remain depicted across Lake and Chaffee
Counties, central portions of Saguache County, western portions of
Fremont County, western Rio Grande County, and most of Conejos County.

Abnormally dry (D0) conditions are now indicated across the rest of south
central and southeast Colorado and include Teller County, eastern Fremont
County, Custer County, and the rest of Costilla, Huerfano, Las Animas,
Pueblo and El Paso Counties. Abnormally dry (D0) conditions are also
indicated across Crowley and Otero Counties, as well as the rest of Kiowa,
Bent, Prowers and Baca Counties. Abnormally dry (D0) conditions are also
depicted across eastern Saguache County, Alamosa County, eastern Rio Grande
County, and north central portions of Conejos County.

DROUGHT IMPACTS...

FIRE DANGER...

Abundant moisture across much of south central and southeast Colorado
has helped to accelerate green up and curtail fire danger across the
region.

The latest information on fire bans and restrictions across the area
can be found at: www.coemergency.com/p/fire-bans-danger.html

AGRICULTURAL...

Recent precipitation has helped to replenish soil moisture across
eastern Colorado, with data from the May 16th, 2021 USDA Colorado
Crop Progress Report indicating western portions of the Colorado
remaining extremely dry. The Crop Progress Report indicates 35
percent of topsoil conditions around the state rated at short or
very short, as compared to 53 percent being rated at short or very
short in the previous week. As for subsoil moisture, 56 percent were
rated at short or very short, compared to 64 percent being rated at
short or very short in the previous week.

HYDROLOGIC...

NRCS data indicated May 1st statewide snowpack was down to 72 percent
of median, which is 79 percent of the available snowpack at this same
time last year. However, with the abundant precipitation through the
middle of May thus far, statewide snowpack as of May 20th remains at
72 percent of median, with notable gains in the eastern basins.

In the Arkansas basin, May 1st snowpack was at 76 percent of median,
which is 101 percent of the available snowpack at this same time last
year. However, as of May 20th, snowpack in the Arkansas basin is at
81 percent of average overall.

In the Rio Grande basin May 1st snowpack was down to 58 percent of
median, which is 128 percent of the available snowpack at this same
time last year. However, the Rio Grande snowpack has fallen to 45
percent of average overall, as of May 20th.

NRCS data also indicated statewide water storage was at 85 percent of
average overall at the end of April, compared to the 100 percent of
average storage available statewide at this same time last year.

In the Arkansas Basin, water storage at the end of April came in at
69 percent of average overall, as compared to 87 percent of average
storage available at this same time last year.

In the Rio Grande Basin, water storage at the end of April came in at
74 percent of average overall, as compared to 78 percent of average
storage available at this same time last year.

May 1st streamflow forecasts in the Arkansas basin ranged from 81
percent of average on the Cucharas River near La Veta, to 64 percent
of average on the Chalk Creek near Nathrop in the May to July
timeframe. However, June 1st stream flow forecasts may increase due
to the abundant precipitation across the Arkansas basin through the
month of May thus far.

May 1st streamflow forecasts in the Rio Grande basin range from 76
percent of average on Culebra Creek at San Luis, to 27 percent of
average on the San Antonio River at Oritz in the May to July
timeframe.
