Don't know about the location in Pune. But I can suggest some nice spots near Lonavala. Not Carp but surely some nice size catches.
3 Places near lonavala where you can surely hit good catches.
1st one being Tungarli Dam near lonavala. There are some very nice spots to catch here as the water levels have been sustained for years and big fish do move around here.
2nd Indrayani river near kamshet. This river gets joined from a damn and there are big fish that get washed along in the same. Kamshet has a good place as the water is not too deep and you can surely find big catches here. Patience is required though.
3rd is a place near lohagad. There is a village called Devale. You have to go here from Malavali by taking a left from the old highway at karla phata. Do go till the station and then ask any one for directions. As you reach this village you will find a nice pond. I call this promise land. Put anything and you will get a bite. The big ones are a bit tough to catch as the chilapis and other fish take the bait most of the time. My personal Fav.
Do let me know if you wish to tag along or want to know any other locations.
Thank you so much, I suggest we all make a plan and visit one of these places, whats the bait, tackle needed?
