Salmon Sweating It Out in Sacramento River

Since the water temperature standards to preserve fisheries in the Sacramento River have been relaxed spawning success will likely be much less this year.

As of noon on the 30th of August the water temperature at Jelly's Ferry was 57.2 F. which is 1.2 degrees warmer than the desired top limit of 56F. As the water temperature increases the survival of salmon eggs and fry decreases. The eggs that do survive produce smaller, weaker fry that have less chances of survival. Thus the spawning habitat has essentially been reduced to the river north of Balls Ferry.

This years decision to allow warmer water to flow in the Sacramento is not good because numbers of juvenile chinook salmon passing the Red Bluff Diversion have been in steady decline since 2006.

The Sacramento River was once famous for its four runs of chinook salmon but now the winter run is endangered and the spring run is threatened with extinction. Unless two breeding sub-populations of chinook are establish above Shasta Dam soon in their former spawning habitat, we will lose two runs. Keep in mind that before Shasta Dam was built there were over 200 more miles of spawning streams available to the chinooks. Now they are lucky to have 45 miles in a good year.

To allow the salmon access to their 200 miles of former spawning grounds that are past the Shasta dam the immediate answer is to build fish ladders. This solution can do for the present until the dams are removed and wind, tidal, and solar power which transforms to electricity can take water from the Ocean, and drop the salt out in Saline plants, then pump the fresh water to source need at any amount year around through water pipelines. That way keeping water temperature at optimum degrees for salmon spawning.

Remember there is no shortage of water but only a shortage of genuine imagination about using new millenium technology to allow a planned optimum water level and temperature for salmon egg hatching and growth.

With the use of the renewables for energy there would be such surpluses of water that no water shortage would happen. With electricity in abundance cold, hot, light, communication and transportation would be available every time. No more blackouts.

This answer of course depends on American working class intelligence to qualitatively move to the next higher level, so even water would be available for all organic agricultural needs as well as fresh water for drinking.

No shortage of water exists if the Pacfic Ocean is recognised as a source of water for the whole of California, the West Coast and indeed in the larger sense for all coastlines around the world.

Workers of the world unite!! Build hatcheries on all rivers for the fishery. Build organic agricultural communes. You yet have a world to win!!
