Comments Due on the 3 Dams by April 16

Plans are moving forward to approve putting rock dams in three sloughs: False River (just west of Franks Tract and the typical navigation route for boats traveling from the South Delta to San Francisco), Sutter Slough and Steamboat Slough (in the North Delta). These would impact boating and navigation. Worse, they are being proposed by the water contractors to enable them to continue to over-export water south.

Opinions about the dams vary. There is a chance the False River one could actually help water quality in the South Delta. However, there are more that have negative opinions:

  1. They could (to me, it seems likely) become permanent. They definitely will be full-time over this summer since they are rock dams, not like the previously proposed opening gates.
  2. They are not planned to be fully removed. The wing dams on the side will remain. What will that do to the water flow during high tides? Will it be safe to boat through?
  3. There is a massive hyacinth/egeria densa problem in the Delta that is caused by low water flows. Frank’s Tract could become a meadow if the water flow is tampered with. Marinas are already having to spend millions of dollars of their own money to control invasive plants. If there are dams on Steamboat and Sutter Sloughs, the hyacinth problem there will be horrendous as there will be little or no water flow.
  4. This will have a negative effect on boating all over the area. False River is a well used navigable waterway as are Steamboat and Sutter Sloughs. The boating and marina industry is already suffering in the Delta along with restaurants and resorts.
  5. I worry that the barriers are part of the overall plan to “wall in” the delta and create a pipeline from Sacramento to the Forebay to export water south. These dams are 3 of a dozen or so that were seen on the BDCP maps in 2009 as part of the “through-the-Delta” peripheral canal plan.

    Mr. Guthrie, In regards to the two temporary dams on Sutter & Steamboat Sloughs, why not dam Georgiana Slough and close the Delta Cross Canal gates ? Any navigational chart of the area will clearly show that Sutter Slough enters into Steamboat Slough. Steamboat Slough itself parallels the Sacramento River and comes together within a few hundred yards of The Sacramento River North & upstream of Rio Vista.
    If the gates at Walnut Grove are to be left open and Georgiana Slough is not dammed then the excess water will be diverted to the San Joaquin River and NOT the Sacramento River which is to hold back the salinity from San Francisco Bay as has been stated in the Sacramento Bee..
