Recently I have been fielding a lot of questions about Local ET Rates and ET coefficients for Delta County. Below is a link to the Colorado Irrigation guide; a supplement to the National Engineering Handbook – Irrigation Guide.

This is a great resource for those interested in learning more about ET Rates and their everyday application in your area.
2015 is By Far the Warmest Year on Record

Weekly Water and Climate Update
January 21, 2016
The Natural Resources Conservation Service produces this weekly report using data and products from the National Water and Climate Center and other agencies. The report focuses on seasonal snowpack, precipitation, temperature, and drought conditions in the U.S.
From the National Oceanic and Atmospheric Administration: The January–December map of temperature anomalies shows that warmer-than-average temperatures occurred across the vast majority of the globe during 2015, combining to bring overall record warmth for 2015, at 0.90°C (1.62°F) above the 20th century average. This easily surpasses the previous record set just last year by 0.16°C (0.29°F). The global temperatures were strongly influenced by the strong El Niño conditions that developed during the year. The 2015 temperature also marks the largest margin by which an annual temperature record has been broken. Prior to this year, the largest margin occurred in 1998, when the annual temperature surpassed the record set in 1997 by 0.12°C (0.22°F). Incidentally, 1997 and 1998 were the last years in which a similarly strong El Niño was occurring. The annual temperature anomalies for 1997 and 1998 were 0.51°C (0.92°F) and 0.63°C (1.13°F), respectively, above the 20th century average, both much lower than the 2015 temperature. Read more>>

I have been busy with general Irrigation Water Management and helping people with their flow measurement and irrigation. But I thought I would do a quick update on drought conditions in Delta County. We have moved back into D2 drought conditions for the entire county. Hopefully we get some good monsoon moisture in July to help stop the drought progression this summer.
Alot of the exceptional and extreme drought through the central mountains and the western slope has eased up some, but southeast Colorado is still really suffering. Delta County is still in Moderate and Severe Drought Conditions.
Good news everyone we are still at 81% for the state median compared with 30% last year. The northern end of the state is faring better than the southern end. Gunnison basin is still looking pretty fair.
Rye planted in the fall to follow up grain corn for a winter cover crop and weed control. Producer was a little worried that it would not come back in the spring, but has been very pleased with the early spring growth hs is getting out of it.
Good news – everyone we are up to 85% statewide for Colorado or double of what we had last year at this time. If these storms continue we might hit 90% yet. Gunnison Basin is up to 88%.
I thought i would post an update of drought conditions in Colorado. It looks like conditions have eased a bit in Delta County, and this moisture that has been moving through can only help!
