Our guest
was Ann DuBay, one of the Sonoma County Water Agency’s Public Information
Officers.
Ann has been
in her job for 1.5 years. She speaks to many community groups to help the
Water Agency spread the word about its challenges. These include a
required 15 year program of habitat restoration on Dry Creek, the
connection between Lake Sonoma and the Russian River. The “Biological
Opinion” rendered 2 years ago found that high flows in the river and Dry
Creek made it difficult for 3 species of fish, steelhead, coho, and
Chinook salmon, to survive. Some info:
- The
SCWA controls reservoirs and flow for water supply purposes, and the
Army Corps of Engineers for flood control.
- Ten
years of studies (cost: $12 million) resulted in plans for restoration
projects in Dry Creek and a need to prohibit breaching of the sandbar at
the mouth of the river every summer to protect young fish.
-
Studies examined alternatives for pipelines from Lake Sonoma to the
river. SCWA recently decided to drop that project from its current
efforts, which prompted a lawsuit from several cities concerned with
protecting their supply.
- Last
year, the agency provided 54,000 acre-feet of water to its contractors,
well short of the current permitted limit on its take from the river of
75,000 acre-feet.
-
Besides its primary contractors, they supply 5 other, smaller customers,
and in off-peak times, Marin Municipal Water District.
- On
groundwater, they’ve worked with the USGS to assess Valley of the Moon
underground water supply, as they did already with Alexander Valley, the
Joy and Riebli Roads areas, all working with property owners on a
voluntary basis. Part of the studies focused on identifying aquifer
recharge areas.
-
Desalination was discussed, and Ann reported its downsides: great energy
use, and a “brine” extract that’s difficult to dispose of.
