Irrigation districts in the Hood River Valley are asking water users to reduce their consumption by 15 percent to help alleviate the potential for shortages later in the summer.  Warm temperatures in May led to faster than normal snow melt which irrigation districts would normally use during the hot summer months.  Les Perkins of Farmers Irrigation District says voluntary cutbacks right now can keep water flowing later in the summer.  Farmers is working on an expansion of Kingsley Reservoir that will allow them to capture more early run off when there is an early snow melt.
