I thought you might be interested in what lakes have the biggest watersheds, so below is a list of each lake’s watershed size ordered from largest to smallest, along with the change in water level from December 13th, 2010 (prior to the rain storms) until January 2nd, 2011 and the other source(s) for water for each reservoir.

|Reservoir||Watershed (square miles)||Water Level Change||Other water source(s)|
|Lower Otay||99||+.96||Aqueduct, upstream releases|
|San Vicente||74||+8.28||Aqueduct, upstream releases|
* denotes the lake reached max capacity during the time period and excess water spilled over.
