Drought - 1987-1992

Event Summary:  7 year drought, from 1987-1992.    This period saw the worst water shortage since the 1977 drought.   In 1987, Idaho requested $5.8 million in Emergency Conservation Funds to aid drought-stricken farmers.   In 1988, in Oneida County the Deep Creek Reservoir was shut off half-way through irrigation season because the water level was so low it was filling the sprinkler system with mud and silt.   Throughout the drought, reservoirs were consistently below capacity, resulting in irrigation water ending earlier than normal, crops being plowed under or not planted at all, and recreational activities being curtailed.   The drought caused high water temperatures in rivers, and the lack of perennial grass growth caused livestock to be removed from public lands early, while wildlife starved in many wintering areas.  Conservation measures were instituted for residential and commercial use.  Wells used for residential and agricultural sectors ran dry, and a moratorium on new wells was instituted.   In 1992 alone, $500 million was lost in agricultural production.

County Summary: 7 year drought (1987-1992) saw the worst water shortage in the state since the 1977 drought.
