Under extreme drought conditions, the combined flow of fresh water from all of the San Joaquin river's tributaries is no longer sufficient to stem the brackish flows that come in from the bay on every tidal cycle. State officials have gone so far as to build levees across major saltwater in-flows in times of especially severe drought. [7]
An undated report on the University of California: Imperial County website provides these specifics: "Salton Sea salinity is about 44,000 mg/L, that is about 4.4% salt. The amount of salts that is deposited in the Imperial Valley agricultural land with irrigation water is about 4 million tons of salts annually.
Suisun Marsh, 116,000 acres (470 km 2) of land, bays, and sloughs, is one of the largest estuarine marshes in the western United States. Geologically, the Suisun Marsh is the product of water-borne sediment deposition, carried from the Sacramento and San Joaquin Rivers into the San Francisco Bay.
Seal Slough, also known as Marina Lagoon, is a narrow winding tidal channel through a tidal marsh in San Mateo [1] and Foster City, California. [2] This slough has been the object of a wetland restoration project in recent years to enhance habitat value. [3] Dredging has been carried out in Seal Slough since at least 1954. [4]

California's coastal salt marsh is a wetland plant community that occurs sporadically along the Pacific Coast from Humboldt Bay to San Diego. This salt marsh type is found in bays, harbors, inlets, and other protected areas subject to tidal flooding .

A tidal asymmetry is a difference between the duration of the rise and the fall of the tidal water elevation and this can manifest itself as a difference in flood/ebb tidal currents. [19] The tidal asymmetry and the resulting currents are important for the sediment transport and turbidity in estuaries and tidal basins. [ 20 ]
