13. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
Divide County: Severely Dry. There have been no significant rains this spring for most parts of Divide county. Crop growth is delayed and there has been minimal cool-season forage production on pastures and hayfields. Lack of forage production on pastures and haylands. Cattle producers are culling their herds to reduce stocking rates. Crop and hay yields are being significantly impacted by the drought conditions.

14. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
Williams County: Moderately Dry. Most of western Williams County has had less than 1.5" of rain since snow melt in early April. Top soil is dry and late planted crops are exhibiting spotty emergence. Northwestern Williams County and western Divide County are especially dry. Scattered showers that have come through the area have not provided significant moisture, less than 0.2" in most places the last 2 weeks. Spotty crop emergence. Pastures slow to green up. Alfalfa stand I manage is very short for the 2nd week of June; I anticipate much less hay will be made 1st cutting than expected. Dry conditions have farmers worried about emergence and establishment of crops. Lots of farmers talking about the need for rain. One producer worried about lack of hay production this year as first cutting (has not happened yet) will not yield as much as he was expecting. 

15. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
Ward County: Moderately Dry. Conditions continue to deteriorate. Grass is heading out at shorter heights and browning is occurring. Crops are becoming moisture stressed as well. Reduced stocking rates, supplemental feeding later into the spring, searching for more pasture land, culling deeper into herd. 

16. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
McHenry County: Moderately Dry. The pastures are shorter than a putting green on a golf course. There have been several failures in crop germination, or where the crop has germinated and died. Several farmers have had to replant. Stands are looking very poor. Concerns: Water, forage (ZERO hay crop available this year), pastures are in extremely poor conditions. Deep culling procedures, selling what doesn't fit into their protocols, looking at buying forage from outside the area. There is a standing burn ban in our county and surrounding counties. Forage production is extremely poor, pastures are not going to be able to be grazed more than 1-2 months at the most.

17. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
Benson County: Severely Dry. No subsoil moisture, some areas have had little rain. Plus we were in a drought the last 2 years going on DRY Grass and pasture drying up. Grass heading out premature. If we don’t get rain we will see reduced crop yields, Hay crop has been impacted

18. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
Pierce County: Moderately Dry. Un-irrigated lawns are already burning up. Pastures are showing grazing stress as there is not enough subsoil moisture for regrowth and we have not received sufficient rains to stimulate regrowth. Sloughs are continuing to recede further. Crop producers are concerned about small grain yield establishment as the young crops are much stressed. Cattle producers are worried about having enough grass through the grazing season and if they'll get enough hay as most have used up their carryover supplies with delayed pasture turnout. Emerged crops are showing signs of stress and some producers are concerned that later season crops may not germinate. Pastures and hay meadows are already stressed from 2 previous years of drought and these grasses are 3-4 inches shorter than previous years with many heading out early.

19. Weekly Drought Impact Collection Based on the NDSU Weekly Survey of Extension Offices
Rolette County: Moderately Dry. Pastures have little grass. Hay crop is going to be short. Shortage of pasture, water supply, short hay crop rotating pastures a lot sooner hoping for rain. Pastures are short, hay crop is short, stock dams and sloughs are low.
