Hydrology
The Kali Bein River, originating near village Dhanoa, upstream of Budho Bark Regulator in Hoshiarpur District, formerly a main tributary of the Beas River feeds the Wetland and the Lake. The Bien has now become an independent river due to siltation and westward swing of the Beas River. Agricultural development dominates the catchment of the wetland. The Bien river has contributed to the formation of fertile plains by bringing down large sediment loads during floods. Depth of water in the Lake has a seasonal variation of 3.05 m (10 feet) to 7.62 m (25 feet) depending on the season and inflow discharge. Catchment area is mainly under agriculture. The wetland is in the semi-arid zone and receives an average annual rainfall of about 620 mm. The temperature varies from a maximum of 450 C in summer to an average of 60C during winter with occasionally freezing temperatures.
The Kali Bein and its wetland provide water supply for agriculture in the Kapurthala district, recharges the ground water, drains excessive rainwater from sensitive crops like wheat, potato, etc. and acts as a sponge by absorbing the flood waters.
