I am a beginner haskell programmer. I am interested in data structures implementation (all from basic ones like stack, queues etc. to advance ones like balanced binary trees, graphs etc.) in haskell. It would be really helpful if someone can point some good references for the same.

The fgl paper[1] is highly readable. It explains and solves the issues a functional approach has to overcome that an imperative approach can simply hack around and gave me many important insights into how to think in a functional way as I was starting to learn Haskell. YMMV, but if you're a decent imperative coder and/or got any kind of scheme or ocaml experience most of it shouldn't be too hard to follow.
