2018 ends with improving drought conditions in Blaine County
December 12, 2018
The amount of water available and the fertility of soil has dictated the success of farmers since they first started planting fields way back when.
Through the years we have developed means to improve the yield one can expect a field to provide and the best crop to plant for expected conditions but in the end it all comes down to the amount moisture the region in question receives.
A county by county map of Montana produced in part by the National Weather Service, the Department of Natural Resources and Conservation (DNRC), The Montana Climate Office and the Montana State Library shows the state as improved its drought conditions across the board when compared the monthly map released by the collective this November.
Their are two reports easily available to everyone. One is released on a weekly basis and the other is updated monthly and can be viewed at https://mslservices.mt.gov/Geographic_Information/Maps/drought/.
The process of determining the drought rating is a thorough process and goes well beyond the four groups that head up the report, "We coordinate with people in agriculture across the state," said Megan Syner of the National Weather Service. "We reach out to several agencies at the Local, Tribal, State and Federal levels to look at scientific data to address drought conditions. We also visit with farmers and landowners to collect anecdotal evidence as to actual conditions on the ground."
There are five Drought Classifications:
D0 - Abnormally Dry, Short-term dryness slowing planting, growth of crops. Some lingering water deficits. Pastures or crops not fully recovered.
D1 - Moderate Drought. Some damage to crops, pastures. Some water shortages developing. Voluntary water-use restrictions requested.
D2 - Severe Drought. Crop or pasture loss likely. Water shortages common. Water restrictions imposed.
D3 - Extreme Drought. Major crop/pasture losses. Widespread water shortages or restrictions.
D4 - Exceptional Drought. Exceptional and widespread crop/pasture losses. Shortages of water creating water emergencies.
In November of 2017much of the state was considered to be in some sort of drought condition and showed Blaine County to be in a D3 - Extreme Drought condition. in the year since Blaine County has saw it's drought rating improve to D0.
"It's taken over a year to move from D3 to D0," said Syner. "Record snowfall across the are in February certainly helped."
To date Blaine County has received 9.6" of moisture in 2018 a slight decline from the annual average of 12.7".
According to Syner the excessive moisture from last winter came at a time when the ground could best utilize and states that drought conditions are very intricate and can improve or decline rapidly.
The heavy snowfall last winter greatly improved top soil moisture levels but the further into the ground you go the worse the conditions get.
As of November 26 Syner says the 81% of the top soil across the state is listed in good condition. Pasteur/range conditions vary greatly with 35% listed in fair condition, 32% in good condition, 10% in excellent condition, 15% in poor condition and 8% in extremely poor condition.
Across the state expectations are expected to continue to improve as long as we receive adequate snowfall ans normal spring rainfall.
"May and June are typically the wettest months in Montana so it is always a critical time in seeing what direction conditions will go," said Syner.
January and February are normally the dryer months across the state as related to precipitation levels adding more importance to spring rain, "Not much rain in May and June could lead to an increase in drought across the region," concluded Syner.
The Montana DNRC, The USDA/FSA Office in Chinook and the National Weather Service are all easily accessible places for folks to visit either on-line or in person to check on current conditions in the region.
