Global Warming Versus Salmon: Dam If You Do, Dam If You Don't

Big dams must be decommissioned in stages in order to allow the sediments to be slowly eroded, hoping that most will not migrate downstream for decades. An excellent discussion of dam removal can be found at the U.S. Forest Service website and by Gordon Grant.

Gordon Grant named 2016 American Geophysical Union Fellow

Research hydrologist Gordon Grant has been named a Fellow of the American Geophysical Union (AGU), becoming the first U.S. Forest Service researcher in the program’s 54-year-history to receive this prestigious scientific honor.

Sierra Nevada Snow Won't End California's Thirst

Contributing to the problem is the fact that there are many more trees here than there used to be. A century ago, Dr. Safeeq said, Yosemite had perhaps 80 trees an acre; now the number is closer to 250. That means more of the melting snowpack never gets off the mountain to the valley below, he said. The greater number of trees is due in part to years of forest agency policies under which small natural fires were quickly extinguished to protect homes and other property in the mountains.

Central coast water supply is unaffected by snowpack levels

"[The streams] always get down to about the smae level. So the year-to-year variability in low flow in actually much lower than you might think," Grant said.

Gordon Grant (U.S. Forest Service), the conference’s Borland Lecturer in hydraulics, put forth a hypothesis of critical flow in mobile-bed streams [Grant, 1997].
