So, I finally made the hike to San Gabriel Reservoir.

For those not familiar with the reservoir, it's a large body of water with a very limited amount of public access. To make it harder, actually getting to the accessible spot requires a long, steep trek down a fairly dangerous path. I don't recommend trying this one.
The water was rather murky, but the inlet with the creeks entering was quite clear. I spotted a large school of carp feeding in the shallows. Tossed a tiny micro crankbait on my ultralite trout rod out front, and WHAM, hookup. The sucker inhaled the crankbait, no snag, and put up a heck of a fight on light line. Also landed a small largemouth bass.
Really an interesting reservoir. Spotted a fly fisherman out there too, didn't see him land anything. Would be a neat lake to kayak or float tube, if it was allowed.
