During monsoon CWC (Central Water Commission) monitors water level at several hundred sites in the county and publishes this information on its Flood Forecast website[I]. The website has three ways to get this information: Data Flow Map, List Based Exploration, and Hydrograph view. The Hydrograph view provides information for past 72 hours, supposed to be updated every hour. This is in addition to the list of current forecasts listed on the website.
Since 2018, SANDRP has been analyzing CWC’s flood forecast website in zone wise manner. After examining status of flood forecast and monitoring sites in North Indian[II] states, this overview is for North East India region covering Arunachal Pradesh, Assam, Meghalaya, Manipur, Nagaland, Tripura, Mizoram and Sikkim states. This also includes part of North West Bengal that is in Brahmaputra basin. Our 2018 and 2019 analysis on the North East region can be seen here[III] and here[IV]. .

ARUNACHAL PRADESH
Arunachal Pradesh had 11 flood monitoring sites comprised of 2 Level Forecast (LF) and 9 Level Monitoring (LM) sites which were increased to 21 by adding 1 LF and 9 LM sites. As of July 2022, the CWC has added 9 more LM sites in the state taking the final tally to 30 sites including 3 LF and 27 LM sites.
CWC has corrected several inaccuracies which were earlier highlighted by SANDRP. However, there are still some issues as mentioned below which require CWC’s attention.
The state has no Inflow Forecast (IF) site. Highest Flood Level (HFL), date for Yinkiang LF site is still missing. The river name, WL, DL, HFL and date has been changed for Namsai LF site without any clarification. River name for Bolent and Jotte LM sites has been changed from Siyum to Siang and from Dikrong to Sinki respectively. Name of Muruga bridge LM site has been changed to Murga bridge.
Out of 27 LM sites HFL, date is not mentioned for 9 sites while hydrographs for 5 LM sites is inactive which means only 22 LM sites are currently working. Additionally, hydrographs for most of the sites are running late by 6 to 3 hours.

ASSAM
As of July 2022, there are 83 sites listed in the state. In last 2 years, CWC has upgraded 6 LM sites into LF sites, added 3 new LM sites and has removed 39 LM sites; list of all these sites are given in separate tables below.
Moreover, CWC has repeated 2 LF and 2 LM sites while 2 LM sites are inactive. These 6 sites are mentioned but not calculated in this analysis. Therefore, currently there are 77 flood monitoring sites active in Assam including 36 LF and 41 LM sites. The state has no IF site. The other problems in LF and LM sites in state are mentioned below separately.
Assam: Issues in LF sites 1 Mathanguri was earlier LM site in Barpeta district with 102.28 m as HFL dated 30.10.1973. It has been upgraded into LF site in Chirang district and HFL has been changed to 100.28 m without the date. New HFL is lower than old one.
2. Bokajan LM site has been upgraded into LF site. Its WL is missing.
3. CWC has increased WL and DL for Numaligarh, Neamatighat and Puthimari NH Rd Xing LF sites without any explanation.
4. The date for previous HFL for Dhubri LF site was changed to 28.081988 from 01.08.1989.
5. The Mathanguri LF site is now listed in Chirang district. Its HFL is changed to 100.28 m without mentioning the date. Earlier it was put in Barpeta district with 102.28 m as HFL dated. 30.10.1973. The old HFL is higher than the new one.
6. CWC has 2 sites named Dholai. Previously both were LM sites with same HFL, date. But now one has been upgraded into LF site for which WL is not given.
7. CWC has upgraded Fulertal LM site into LF site but has not given the WL which was shown in hydrograph on 21.06.2022 when old HFL was breached at this site.
8. CWC has repeated Matijuri site (previously spelt Matizuri). One is LF site and second one is LM site with same HFL, date.
9. HFL date for Annapurnaghat has been changed from 02.09.1989 to 01.08.1989.
Assam: Issues in LM sites 1. CWC has changed districts for Matunga, DRF, Harangajao, Suklai, Panbari, Bahalpur, Lakhipur, Borkhola, Fakirabazar and Badarpur Ghat LM sites. Similarly, river names have been changed for Badarpur Ghat, Dihingmukh and Fakirabazar LM sites. The old districts are given separately in rows below the particular sites.
2. CWC has also changed the name of AP Ghat and BP Ghat to Annapurana Ghat and Badarpur Ghat. Interestingly, there are 2 LF sites with same name.
3. The hydrograph for DRF LM site suggests technical error in data entry on 19.06.2022 when the site is mentioned as crossing old HFL.
4. The previous HFL 101.05 m dated 18.061995 for Gelabil LM site is higher than 99.34 m dated 29.08.1999.
5. The old HFL for Suklai LM site 76.18 m dated 12.09.1983 is higher than 75.73 m dated 25.09.2018 and 75.85 m dated 25.06.2020 which is its current HFL. It is worth to mention that the river has touched the 75.85 m HFL on 16.06.2022 this year.
6. The Dudhnai and Dudhnoi LM sites are same but listed twice by CWC.
7. CWC has added Bazar in Gumra LM site but has not named the river which is given by us on the basis of previous record.
8. HFL dates for about 11 LM site is missing. Hydrographs for several LM sites is running late by 02 to 05 hours.

Summary
As per CWC-FF website, there were 148 sites in North East India and Brahmaputra basin in West Bengal comprising of 42 Level Forecast, 100 Level Monitoring and 6 Inflow Forecast sites. In 2019, CWC had added 96 sites taking total tally to 244 sites including 55 Level Forecast, 184 Level Monitoring and 5 Inflow Forecast sites in the region.
As of July 2022, the total number of flood monitoring sites have come down to 201 which includes 68 Level Forecast sites, 128 Level Monitoring sites and 05 Inflow Forecast sites. Out of 128 Level Monitoring sites 23 are either inactive or repeated. Excluding these would further bring down the number of active sites to 178. This is contrary to CWC’s claim of increasing flood monitoring stations in the country.
There is NO Level forecast site in 4 states of Meghalaya, Manipur, Nagaland and Mizoram while Sikkim has 5 Inflow Forecast sites. The analysis shows that CWC has been arbitrarily adding and removing flood monitoring sites in the region. Most of CWC’s hydrographs in the region are running late by several hours which has emerged as a new problem across the states in North East.
The specific issues and problems with flood monitoring sites have been mentioned in state wise manner above. In our 2019 analysis for North East India[V] we had highlighted some major gaps in CWC’s flood forecast in the region and most of these have remained unaddressed so far.
