From KOAA.com (Sam Schreier):

Last week, a quarter of the state (25.49%) was under extreme drought. Now, the percentage has risen to 32.96%, which is roughly one-third of the state.

Conditions associated with extreme drought include:

Pasture conditions worsen

City landscapes are dying

Large fires develop

Rafting, fishing, hunting, skiing are reduced; fish kills occur

Grasshopper and insect infestation are noted

Reservoirs are extremely low; mandatory water restrictions are implemented; water temperature increases

Drought conditions started to develop in the early Spring due to a drier than normal March and April.
