California region, with its 10 4-digit subregion hydrologic unit boundaries.

Most large reservoirs in California are located in the central and northern portions of the state, especially along the large and flood-prone rivers of the Central Valley. Eleven reservoirs have a storage capacity greater than or equal to 1,000,000 acre-feet (1.2 km 3 ); all of these except one are in or on drainages that feed into the Central ...
California ended its “miracle” water year on Saturday with enough rain and snow to fill the state's reservoirs to 128% of their historical average, making it among the wettest years in ...
