Among other Indians in fray, Manav Jaini (73) was tied 29th, while Abhijit Chadha, Sujjan Singh and Angad Cheema were tied 56th with Lahiri.
Himmat Rai (77) and Abhinav Lohan (78) were struggling further down, while Amardip Malik (79) and Digvijay Singh (80) were certain to miss the cut.
Chowrasia said, "I have been starting well, hitting well, but somehow I have not managed to finish tournaments properly. I have had two top-five finishes and was 11th at Singapore, but I feel some good results are just around the corner."
Meanwhile, Lahiri needing to get into inside top-60 of the world within a fortnight – he is right now 64th – had a tough time.
"It was a frustrating round. I don't think I played horribly. I just made some poor decisions and struggled on the greens. The greens are a bit grainier than what we've played on this year," said Lahiri.
"I double bogeyed the eighth hole but it wasn't only about that hole. I misjudged the wind there and hit it to about five yards too far. I hit it to the worst possible place because you can't hit your ball past the flag."
He added, "I missed a bunch of putts inside six feet and you can't do that to have a good score. I don't think I'm out of the tournament yet. It is a tough course and if you can play consistently then you can get decent score. I honestly don't think I'm out of the tournament."
Lahiri needs a win this week to give himself a chance to break into the top-60 in the world by May 26th to qualify for the US Open in June.
Bangladesh's Siddikur Rahman fired his best score at the challenging Wack Wack Golf and Country Club to share the honours with Chan Kim at six-under-par 66.
