    Battle of the Bays: The Backstory You Need

    California water managers said the late season rain threw them a curve ball this week.

    The rain is coming down in the extreme northern portion of the state, but it is going to be felt as far south as Sacramento.

    The Sacramento River is expected to rise in the capital area because water officials are being forced to release water upstream from Lake Shasta before the big storm.

    Heavy rain is expected late tonight and Friday in Redding and areas to the north.

    [BAY] Drizzle to Sizzle Soon - Rob Mayeda's Forecast
    Some rare early June rain will drop into Northern California with parts of the Bay Area having a chance for some showers mainly north of San Francisco at least through Friday. Starting this weekend, high pressure begins building in from the Desert Southwest, promoting a warming and drying trend into early next week. Look for 70s and 80s inland to wrap up the weekend with a few areas soaring into the 90s from Monday-Wednesday.

    The river may rise about a foot and a half in Sacramento in the coming days, leading to a warning for downstream boaters to expect especially fast, cold water and many floating logs this weekend.

    Lake Shasta is 98 percent full, leading the U.S. Bureau of Reclamation to release water in anticipation of increased rain runoff and snowmelt.

    Current releases are about 10,000 cubic feet per second, but managers are preparing for releases of up to 30,000 cubic feet per second. Last week and again on Tuesday, the Anderson Cottonwood Irrigation District lowered the level of its diversion dam near Market Street in Redding.

    Irrigation district manager Stan Wangberg said that will prevent the dam from being bombarded and potentially damaged by floating debris if river levels are dramatically increased.

    Managers of Shasta Dam said they still do not have any plans to allow water to flow over the top of the dam, which last happened in 1998.

    However, if flows are increased above 18,000 cubic feet per second, some water will begin to flow out of valves on the face of the dam near the top. contributed to this article.
