Re "One shot to save the Delta's ecology" (Forum, Dec. 1): How will diverting more than half of the Sacramento River's Delta flow to Southern California help restore the wetland habitat? The article says that today about 3 percent of marshes remain and 23 percent of seasonal wetlands remain.This being said, explain to me how removing most of the river flow for Southern California is going to solve the wetlands problem. Isn't the fact that we have already diverted a large portion of water causing part of the existing issue? A report in your paper states an estimated 18,000 cubic feet per minute will be diverted in the two tunnels. It also noted that the Sacramento River's flow is about the same. In this case, two plus two doesn't equal four.
