Chalan Beel, Seasonal lake in Rajshahi, Pabna, and Sirajganj districts, Bangladesh.
Chalan Beel is a large wetland system spanning multiple water bodies that connect through natural waterways across three districts. The land and water mix together here, creating a complex web of channels and pools that shift with the seasons.
Chalan Beel took shape from the shifting patterns of the Atrai and Baral rivers, which gradually molded the landscape over centuries. The waterways continue to be influenced by these river systems and seasonal flooding.
Local fishing communities maintain traditional practices in the wetlands, sustaining their livelihoods through generations of knowledge and techniques.
The best time to visit depends on which aspect you want to see, since the water covers very different amounts of land depending on the season. During the wet months, water dominates the landscape, but in dry periods you can see the land and channels more clearly.
Forty-seven waterways flow through this natural drainage system, supporting 34 species of reptiles and 27 species of mammals.
