I always wonder how nature is assumed to be "wasteful." Since people weren't hunting/fishing in big boats not that long ago, were all those fish in
the seas "wasted" by us not eating them
Likewise, the water in Owens Valley, that has fed into Mono Lake and created those wonderful "tufa" formations, long before LA needed it, was never
"wasted" by the local environment. It fed plants, animals, etc. Mark Twain marvelled at Mono Lake's productivity and wrote about it. (He hated the
flies along the shore)
Maybe it didn't produce a huge agricultural boom, but the ecosystem that evolved relied on that water. When it was diverted via Muholland's aqueduct
lots of bad things happened.
(I know we have a Nomad who lives near Bishop- perhaps she can add some details?)
Examples:
Wildlife: birds nesting on islands in Mono Lake were nearly wiped out as the water level declined and predators were able to reach the nesting
grounds. Ground nesting is common in many areas, but is also a delicate balancing act. These birds included many of the gulls that we see along the
coasts. So the impacts on wildlife were felt hundreds, even thousands of miles away.
Air quality: The groundwater helped keep the alkali dust in place- when LA diverted the water, the 'dust bowl" conditions were so bad that asthma
soared in the valley. It has improved, but the air quality in that region is still worse than it was before the "straw" began sucking water south.
Local groundwater supplies: as surface water is drained away, wells dry up for local households, making it more expensive and reducing its quality.
And in the end, a lawsuit forced LA to conserve water. Guess what: they managed to use much less, once they were forced to, and the levels in Mono
Lake have recovered, along with the birds etc.
Finally, today on the radio I heard Gov. Brown basically say: prepare to be told to remove your lawns if these dry weather conditions continue. The
"recommendations" and "suggestions" that have been used in the past may soon be replaced with mandates. |
It's all in how you look at it, isn't it?
---but a few nit-picky points:
(1) My Family lived in Owens Valley (near Bishop, and near Independence) from the '20's until now----none of them ever developed "asthma", thank Gawd,
and the "dust bowl" statements are a tad overstated, but yes air-quality did deterioriate after Owens Lake and the Owens River bed dried up. That is
now being rectified because of additional Law suits which went against the City of LA, and my Family is involved in that correction at the Lake.
(2) No "Owens Valley water" flows into Mono Lake, now or in the past. But the rest of your "Mono Lake" points are correct except that the Lake is far
from "recovered"-----that will take years, and some very good winter rains and snowpack, but it is rising slowly but surely.
(3) The "Law suits" that you refer to required DWP (city of LA) to reduce some of their diversions from Mono Lake's watershed-----how LA coped with
that was outside the scope of the Law suit, as I understand it.
(4) Owens Valley water tables have fluxuated over the years, but have remained fairly stable most of the time, and few wells actually dried up. Some
surface wild trees did die, however. There have been additional Law suits on this matter that mostly corrected any problems----again the City of LA
lost those battles. They were sucking to much ground water at times, especially during dry years.
Californians do waste a lot of water, especially SoCal residents, and they may be in for a rude awaking, you are correct. Having lived in San Diego
for 30 years, Owens Valley for 10 years, and then the Imperial Valley for another 13 years, I am very familiar with SoCal water problems from a human
point of view..
