do not dispair, man.
I grew up here but lived in the mountains and fished trout exclusively. I was a guide in the summers and eventually got burned on the yuppies and just trout in general....
some tips-
-go to co dep of wildlife and buy the book "fishing close to home".-tons of ponds that see no pressure
-use google maps to find ponds off the main paths
-look to the north (N of I-70). Hogmaster is absolutely right, the Q ,A-town and chatfield are great lakes but they are about it in the south metro.
-Lakewood is named that for a reason

-get a belly boat. lots of small ponds that do not allow boats but let you tube.
-think ghetto. my friends and I have a pond called "the pit" perfectly describes the pond. and it is in a part of town you would NOT go at night. but maybe thats why hardly anyone fishes it and its full of fish...
-look on maps along the major front range rivers thats generally where the ponds will be.
-very very few ponds in CO hold shad. in small ponds in summer i"ve found that if you look to where bugs fall in the water and use small topwaters you can smoke em.
- fish as much as possible definitely use good polarized glasses and pay attention to what the fish are telling you.
