Pelling May 93 to Dec 96 At all the above raingauge sites, data for few months is missing in between. Raingauge sites have also been established near Teesta Low dam projects, Stage-III & IV and are operational since August 2000. Lot of efforts has been made to collect all available rainfall data in the basin but only rainfall data of 11 stations mentioned above is available at present. None of the above rainfall stations lie in the catchment of the proposed project so this data has not been used in the hydrological analysis. 5.3 WATER AVAILABILITY STUDY 5.3.1 Stream flow and River gauges Since Teesta River offers ideal conditions for cascade development of hydroelectric schemes, the discharge passing through the river is measured at various sites by CWC. Recently NHPC has also established its various G&D sites on Teesta river since a number of projects have been entrusted to NHPC as a part of cascade development on the river. These include Teesta-V, and Teesta Low Dam projects, Stage-III & IV. However, no G&D data is available on Ringpi Chu, at or near the proposed dam site of Lingza H.E
