Summary of Impacts (graphics on following slides) Links: See/submit Condition Monitoring Observer Reports (CMOR) and view the Drought Impacts Reporter Hydrologic Impacts Lower water levels are expected across many bodies of waters especially those in worsening droughts. Reservoir levels will hold steady, however areas with minimal, localized rainfall could see diminishing levels. Agricultural Impacts USDA Wyoming Crop Progress and Condition Reports can be found here Fire Hazard Impacts Fire Hazards are low as temperatures are more seasonal and there has been adequate rain and snowfall.
