Lake Fernando Hiriart Balderrama, better known as Zimapán, was built by daming a canyon in 1995 located in the border of the states of Quer étaro and Hidalgo ( half of the lake belongs to Queretaro, the other half to Hidalgo. Gets it 's common name from the town of Zimapán, Hidalgo near by. The lake is 23 square kilometers in surface and in some places exceeds 600 ft in depth. It 's stocked with carp, tilapia, Florida bass and has a population of native cichilds and catfish that existed previously to the canyon and the Moctezuma river being damed. Built for power generation it gets part of it 's water from rainfall but mainly from water treatment plants from Mexico City.
The lake record so far is 11 1/2 pounds, you know that means that nobody has been able to break it but that doesn 't mean there aren 't bigger fish.
It has a huge population of bass between 1-2 pounds ( that 's what you catch 95% of the time ) but ocassinally you do catch bigger fish, actually it 's more a matter of luck than anything else, there 's so many small fish that the biguns normally don 't have a chance against them when it comes to chasing and striking a bait. Cover in most of the lake is non existant or very scarce even though at the area of the springs there 's still some standing timber.
What works in Zimapan ? anything works, any bait you can think about catches fish.
Soft plastics: any soft plastic will land you fish. Prefered rigging methods.- slightly weighted wacky rigs ( split shot above size 5 ), shakey head rigs ( 1/16-1/8 oz ), slightly weighted T-rigs ( 1/8-1/4 oz ), C-rigs, D-shot, Split Shot are the most productive. I don 't advice using heavy weights to sink your baits, the composition is mostly chunk sharp rock and heavier weights hang up too much.
Crankbaits: the paradise of the deep diver crankbaiter, for a lake with such steep sloping banks topwaters work very well.
Spinnerbaits: Willow leaf spnnerbaits slowly rolled also catch you fish.
Jigs: better get some football head jigs otherwise you 'll hang up like mad.
Swimbaits: despite of their size swimbaits work, only catch is what you hook the most is fish about the same size of the swimbait. :
This is how the lake looks like:
A pic of the dam:
The half of the lake that belongs to Queretaro ( Tzinbantzá ) is much better developed than the side the belongs to Hidalgo. In the Queretaro side there 's a lodge and a camp where you can stay, there 's a rock paved ramp and places to camp.
Do not go or plan a trip during the week, the lake is commercially exploited for tilapia and the fisherman choke it with gill nets, Saturdays and Sundays the lake is gill net free.
