Conflict over water allocations from the Sacramento-San Joaquin Delta is the most intractable water management problem in California.The sources of contention are many, but three interrelated issues dominate the debate: whether to build two tunnels that divert water from the Sacramento River, how much water to allocate to endangered fish species, and what to do about the 1,100 miles of Delta levees that are essential to the local economy. All of these issues need to be addressed to reduce unproductive conflict and litigation and resolve our water problems.
