The San Gabriel River used to be a part of the Bolsa Chica marsh. It still does to some extent, but so much of the water has been diverted and is used for the Valley's people. It flows in a cement channel and pours into large pools to recharge the aquifer for 1.5 million people. In the Bolsa Chica tigers ran. There are birds. there are lizards. there are insects of other orders. But, are there tigers? C.s.frosti like me?
