| Glen Canyon Dam |
#92 October 26: An interesting article on today’s editorial
page. This year 4 dams will come down on the Klamath River between the border
of Oregon and California. Originally
built for hydro electrical power they are no longer useful for this purpose,
supplying less than 2% of the power in the region. Dams have been built since man watched the
beavers but out West, a great surge of dams were built in the last 100 years
including the engineering marvels of the Glen Canyon forming Lake Powell and
the Hover Dam forming Lake Mead. Dave
and I have visited them multiple times while traveling out West and mourned their
depleted water levels. According to the editorial, what is “doing them in” can
only be partly blamed on climate change.
Their demise is being caused by poor maintenance which allows silt to
build up behind the dam reducing their ability to generate electricity and
maintain a water level to provide for the municipalities that rely on them for
both drinking and agricultural water and flood control. Added benefits of losing the dams include a
freer flow for salmon and restoration of cultural waters for Native Americans. How
long will these engineering marvels remain useful? Will they endure? It’s hard to fight Mother Nature! 10/30

October 27: When we were in The Netherlands and
Belgium, we noticed several clover leaves and roadsides that were being “mowed”
by sheep and goats. An article in today’s
paper is about an entrepreneur who is providing “lamb mowers” mainly in
Virginia near DC. You can purchase a “weed
and feed” for $195 for 2 hours.
Supposedly the sheep will eat the grass to the optimum 4-inch height
including any weeds. They also leave
rich “fertilizer” behind. Cory Suter,
the self-described “Chief Shepherd” will also see that someone comes behind the
sheep and string trims the edges; so far he hasn’t been able to teach them
that! LOL For $250, you can purchase a “sheep-over” for
bigger jobs. Haven Kiers, an assistant professor of landscape architecture at
UC, Davis is researching the benefits of having sheep “mow” the grounds
there. Her study noted that students
purposely ride their bikes close to the sheep and sit with them, for comfort, especially after exams! 10/30
