Excerpt from Water Supply Outlook for Washington and Federal-State-Private Cooperative Snow Surveys: As of April 1, 1981A mixed bag has also occurred with the streamflow during the month of March. The range of outflows is from 40 percent of normal for the Palouse River, as measured near Hooper, to a high of 109 percent above average for the Kettle River at Laurier. Excellent flows continue to occur on the mainstem from British Columbia with the Columbia having an outflow, as measured at Birchbank, of 39 percent above normal down to The Dalles with an outflow that is 10 percent below average. This low number is probably the result of low flows from the Snake. Our forecasts of streamflow' now range from a high of near 90 percent of normal on the mainstem of the Columbia at Birchbank to a low of 49 percent of normal for the Okanogan Drainage, as measured near Tonasket. A few of the key drainages in the state indicate subnormal flows are expected. For example, in the Yakima system, the forecast for the Yakima River near Parker is for a flow only 56 percent of normal for the april-september period. On the Puget Sound Drainage, we expect the Green River, as measured below Howard Hanson Dam, to flow' only 41 percent of average and the Cedar River, 54 percent. As previously stated, the outflow from Canada through the Okanogan system is expected to be only 49 percent of normal, or acre feet. Individual forecasts can be found following this narrative.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
