The summer irrigation outlook for the Hood River Valley is much better than it was last year at this time.  Oregon State University Extension Service Agent Steve Castagnoli says the current water content in the snowpack is about double from last year, even with recent unseasonably warm weather leading to some early melt and dropped snow-water content about 20 percent below average.  But even with that, he notes the valley is in pretty good shape.  Castagnoli is emphasizing the need for all irrigators to be efficient in their use of water.  He is going to be teaching a class on drip irrigation on Saturday at 11:30 a.m. and 12:30 p.m. during the Central Gorge Master Gardeners Plant Sale at the OSU Extension Learning Garden on 2990 Experiment Station Drive in Hood River.
