Experts warn of impending South Delta water crisis

In a recent government meeting, concerns were raised regarding the deteriorating conditions in the South Delta, highlighting a potential ecological catastrophe. A speaker with dual interests in Delta and export issues emphasized the alarming trend of sediment accumulation in the region, which has reached a critical tipping point.

Historically, it was believed that high water flows during wet years would effectively transport silt out of the Delta towards the bay and ocean. However, observations over the past two decades indicate that this is no longer the case. The speaker recounted a pivotal moment in 1998 when a farmer reported that Old River, a crucial waterway, was nearly dry. This incident prompted a renewed focus on the South Delta's water management challenges.

The testimony included specific examples of the changing landscape, particularly referencing Dowdy Cut, a channel that has seen significant sediment buildup. Once a depth of eight feet, recent surveys reveal that parts of the channel now measure only one to two feet deep. This dramatic reduction in depth is expected to severely impact tidal flows and the overall water movement within the Delta system.

The discussions underscore the urgent need for intervention to address the sedimentation issues threatening the South Delta's water infrastructure and ecological balance.
