the good news is that after september all through until march, the narayani (which is formed downstream from these rivers is full of mahseer and we have confirmed reports of one being caught everyday at devghat ... now this info is for central nepal - an area we believe that has not been explored for mahseer fishing as much as the western region has. we're still exploring here. with a little more digging and footwork along the rivers, we can come up with more on the mahseer movement here.
Facinating stuff yakaty, I'd always assumed that the most productive fishing grounds for mahseer had been sussed out and written about many years ago.
Sure, K. Ashness wrote about the far west a few years back, but many others had recorded Chisapani as a notable fishing venue before then, not least Macdonald in 1948.
Bottom line is that the Karnalli has, and always will be, a far more productive catchment than the Trisulli for mahseer simply because of its geographical nature
Of course, heading further east to Assam & beyond is a different matter again : plenty of unchartered territory there ...
