iam actually from nainital just 7 km away from sattal and have been doing fishing in those lakes mostly fly and spining for mahaseer size is too small 3 or 4 lb fish a rare but also i enjoy going for those illusive fish
i have heard of a cannal near delhi which holds good mahaseer up to 30 lb do any one know
lots of good wishes to IA.com
There were 30 pounders in the Yamuna in Delhi itslef. But their visas expired and so they left with the viceroy back in'47.
The nearest place to delhi where there were any fish till 5 years ago, has also unfotunately been wiped clean thanks to contract netting and pollution.
As far as you Nanital area lakes go, try the old Jubbalpore tricksusing channa and corn. Its worked for me, but requires a lot of time and energy. You'll only get tiddlers on lures here.
Furthermore, PLEASE PLEAE PLEASE remember to handle your fish in the proper manner and release them after a good photo. There are not enough mahseer left, and you are a very lcky guy to have them in your back yard!!!
