NATIONAL HYDROLOGY PROJECT-III
The National Hydrology Project (NHP) is a 100% funded central Sector Scheme under the Ministry of Water Resources River Development and Ganga Rejuvenation, which is to be implemented for a period of 8 years for a cost of ` 25 Crores for the state of Sikkim. The entire Project details are available in nhp.mowr.nic.in. The project is funded under World Bank and follows the World Bank Guidelines.
Hydrology Project is being implemented across the country as NHP, to improve the Planning, Development and Management of Water Resources, as well as flood forecasting and reservoirs operations in real time basis.
Water Resources and River Development Department is the State Nodal Department to pursue and implement the project in Sikkim. This Project broadly has the following components :
Component A: Improving the Water Resources Monitoring System (WRMS) by establishing    network for the meteorological and hydrological stations designed and established for effective collection of water effective collection of water resources data.
Component B: Improving the Water Resources Information System (WRIS) which will strengthen and make available remote sensing and spatial information data to water managers and stake holders through web based portals.
Component C: Promoting Water Resources Operation and Planning System (WROPS), this will ensure usefulness of WRMS and WRIS data sets through Decision support system (DSS) for river basin planning, water balance assessments, climate risk assessments, WQ management, etc.
Component D: Strengthening Water Resources Institutional Capacity Enhancement (WRICE). This will strengthen and build capacity in the Implementing Agencies (States) through establishing infrastructure and communication equipment.

The MOA/MOU for implementation of the project has been approved and signed by the State Government. The activities of the project to be taken up by is contained in the Project Implementation Plan (PIP) for an estimated cost of ` 25 crore which is approved by the Government of India. In order to implement the Project in the state approval of the State Cabinet was necessary.
The Implementation of this project was commenced from the year 2017-18 by setting up a separate State Project Management Unit Office at Sokeythang. The major activities that have been taken up till date are:
1.    Twenty one numbers of locations have been identified at different locations throughout the State for installation of Hydro-Meteorological instruments for collection of real time data. The instruments to be installed are five numbers of Automatic Weather Stations, thirteen numbers of Automatic Water Level Recorder and three number of snow pillows with snow depth sensors. The bid for the installation under the RTDAS is being floated by CWC.
2.    Construction of State Water Resources Information Data Centre which will be the centre for collection and dissemination of all Hydro-Meteorological data in the State. The tender process has been completed and the work order has been issued. Work is currently under progress.
3.    Setting up of Gauge Discharge Stations at various main rivers and its tributaries which will help us to ascertain the discharge of the river and also for monitoring the e-flow. All these data will help in water budgeting. Bid document is under evaluation with Ministry/TAMC.
4.    Trainings for capacity building of State Government Officials. This is an ongoing activity and trainings are attended as and when calls are received from the Ministry/ Organizing Agencies under NHP.
