Bihar Current Affairs 5 September 2026

Welcome to the Ujiyari Bihar Current Affairs notes for 5 September 2026, prepared for BPSC and other Bihar government examinations. The Ganga has crossed its previously recorded highest flood level at Gandhi Ghat in Patna, and around 10.26 lakh people in 11 districts are flood-affected as multiple rivers run above the danger mark. Chief Minister Samrat Choudhary conducted an aerial survey of the flood belt on 4 September and directed ministers and officials to camp in the affected areas. On Teachers Day, the Chief Minister announced five decisions, including the establishment of a state teacher training university and an AI ecosystem in school education in partnership with Microsoft, Google and Sarvam AI. The state honoured 38 teachers with the Bihar State Teacher Award, one from each district. Each item carries a Prelims fact set and a Mains angle, followed by five practice MCQs.

1. The Ganga Crosses Its Highest Flood Level at Patna

Why in News: The Ganga at Gandhi Ghat, Patna, rose to 50.53 metres at 10 am on 5 September 2026, one centimetre above the previously recorded Highest Flood Level of 50.52 metres and 1.93 metres above the danger mark of 48.60 metres, and the Water Resources Department forecast a further rise to 50.62 metres by 8 am on 6 September.

Read the milestone precisely. A river crossing the Highest Flood Level, and staying there, is a different order of event from crossing the danger mark. The danger mark is the level at which precautionary evacuation begins; the HFL is the highest reading ever recorded at that gauge, and a level above it means the embankment and city defences are being tested at a benchmark they have not been asked to hold before.

The rivers in spate. In addition to the Ganga at Gandhi Ghat, the river is above the danger mark at Digha, Hathidah, Bhagalpur, Kahalgaon, Buxar and Munger. The Gandak at Dumriaghat and Hajipur, the Kosi at Baltara, the Burhi Gandak at Khagaria, the Punpun at Sripalpur and the Ghaghara at Darauli are all above their danger marks, and the Kamla, Kamla Balan, Bagmati and the Adhwara group are also swollen.

The response.

The affected districts. Patna, Bhojpur, Saran, Vaishali, Bhagalpur, Begusarai, Buxar, Samastipur, Munger, Katihar and Araria.

Why Bihar floods this way. North Bihar’s rivers, the Kosi, Gandak, Bagmati, Burhi Gandak and Kamla Balan, rise in Nepal and the Himalaya, carry very large sediment loads, and drop them on losing gradient at the plain. The Ganga, along the state’s southern boundary, aggregates that discharge. A monsoon depression over central India, coupled with heavy rain over Nepal, is the standard trigger, and the Kosi, called the Sorrow of Bihar, is the classical example.

Bihar Relevance:

• Prelims: The Ganga at Gandhi Ghat, Patna reached 50.53 metres at 10 am on 5 September 2026, above the HFL of 50.52 metres.
• Prelims: The danger mark at Gandhi Ghat is 48.60 metres; the current level is 1.93 metres above it.
• Prelims: 10.26 lakh people in 50 blocks and 201 gram panchayats across 11 districts are affected.
• Prelims: 27 SDRF and 9 NDRF teams and 693 boats are deployed; 38 community kitchens are running.
• Prelims: The affected districts include Patna, Bhojpur, Saran, Vaishali, Bhagalpur, Begusarai, Buxar, Samastipur, Munger, Katihar and Araria.
• Prelims: The north Bihar rivers Kosi, Gandak, Bagmati, Burhi Gandak and Kamla Balan rise in Nepal and the Himalaya.
• Mains: The Highest Flood Level as a design benchmark for embankments and city defences, and what a sustained level above HFL means (GS1 geography, GS3 disaster management).

2. Chief Minister’s Aerial Survey of the Flood Belt

Why in News: Chief Minister Samrat Choudhary conducted an aerial survey of the flood-affected areas on 4 September 2026 and directed ministers and officials to visit the affected areas, camp there and ensure close supervision of relief and rescue operations.

What the aerial survey does, and does not do. The survey allows the head of government to sight the affected belt directly, verify what is being reported through the district and the department, and set a public signal that command attention is on the field. It does not by itself deliver relief, and its worth is measured by the decisions it produces, not by the photo of the helicopter.

The command chain to remember. The State Disaster Management Authority, chaired by the Chief Minister, is constituted under Section 14 of the Disaster Management Act, 2005. Its District Disaster Management Authority counterpart, chaired by the District Magistrate, is constituted under Section 25 of the same Act. The National Disaster Response Force, constituted under Section 44 of the Act, is deployed on state requisition; the State Disaster Response Force is the state-raised counterpart. The National Disaster Management Authority at the apex is chaired by the Prime Minister.

The context in which the survey happens. Continuous, heavy downpours across Nepal and neighbouring Jharkhand have pushed the Ganga, Son and northern rivers past danger levels, and the discharge from the Son barrage has risen. The state has requisitioned additional NDRF teams and directed the Water Resources and Disaster Management departments to keep continuous patrolling along vulnerable embankments.

Bihar Relevance:

• Prelims: The Chief Minister conducted an aerial survey of the flood belt on 4 September 2026.
• Prelims: The State Disaster Management Authority is chaired by the Chief Minister under Section 14 of the Disaster Management Act, 2005.
• Prelims: The District Disaster Management Authority is chaired by the District Magistrate under Section 25.
• Prelims: The NDRF is constituted under Section 44 and is deployed on state requisition.
• Prelims: The NDMA at the apex is chaired by the Prime Minister.
• Mains: The disaster response chain in a trans-boundary flood event where the trigger is rainfall in the upstream country (GS3 disaster management, GS2 federal coordination).

3. Chief Minister’s Five Announcements on Teachers Day

Why in News: On Teachers Day, 5 September 2026, Chief Minister Samrat Choudhary made five announcements for the state’s teachers, including the establishment of a state Teacher Training University, a separate pay scale for finance-deficit school teachers, and an AI ecosystem in school education in collaboration with Microsoft, Google and Sarvam AI.

The five decisions.

Read the AI decision precisely. An AI ecosystem in a state school system is not a single product, and it will only be as strong as its weakest layer: teacher capability, connectivity in low-tier blocks and a governance chain that keeps content aligned with the state curriculum. A collaboration with two large technology firms and an Indian AI company should therefore be measured against three tests, not one: content, teacher training and service reliability.

Why the separate pay scale matters. Finance-deficit schools are aided institutions where the state meets a share of costs but the pay scale historically trails the regular government scale. A separate pay scale narrows that gap; the examinable question is whether it also brings the terms of service, transfer and retirement into a single framework, since a scale change without service conditions leaves the two cadres unequal on everything except take-home pay.

The wider frame. Teachers Day is observed on the birth anniversary of Dr Sarvepalli Radhakrishnan, the second President of India and a philosopher of the Advaita tradition, born on 5 September 1888. At the national level the National Teachers’ Awards, 2026 were conferred by President Droupadi Murmu at Vigyan Bhawan, New Delhi on 48 school teachers.

Bihar Relevance:

• Prelims: On 5 September 2026 the Chief Minister announced five decisions for teachers, including a state Teacher Training University.
• Prelims: An AI ecosystem in school education is to be built in collaboration with Microsoft, Google and Sarvam AI.
• Prelims: A separate pay scale was announced for finance-deficit school teachers, and pending salaries of Madrasa and Sanskrit Board teachers are to be processed.
• Prelims: The state is to work toward a Banaras Hindu University centre in Bihar.
• Prelims: Teachers Day marks the birth anniversary of Dr Sarvepalli Radhakrishnan, born on 5 September 1888.
• Prelims: The National Teachers’ Awards, 2026 were conferred by the President at Vigyan Bhawan, New Delhi on 48 teachers.
• Mains: An AI ecosystem in state school education and the three-layer test of content, teacher capability and service reliability (GS2 education).

4. Bihar State Teacher Award for Thirty-Eight Educators

Why in News: The state honoured 38 teachers with the Bihar State Teacher Award, 2026 on 5 September 2026, with one teacher selected from each of the state’s 38 districts, including 17 women teachers.

The award, and why the selection design matters. A one-per-district design is a straightforward way to ensure geographic spread, so that recognition does not concentrate in the state capital or in a handful of prominent institutions. That geographic guarantee is what a state-level scheme should deliver, and it is the point that distinguishes a state teacher award from the national award.

Read the composition. Of the 38 awardees, 17 are women teachers, close to but short of half. That share matters because the visibility of women teachers as achievers affects the pipeline of women entering the profession, and the state’s own targets on female enrolment in secondary and higher secondary classes.

The national award for context. The National Teachers’ Awards are conferred by the President of India on Teachers Day at Vigyan Bhawan in New Delhi and recognise outstanding contributions in school education across the country. In 2026 the President honoured 48 teachers. The state and national awards are complementary rather than competing: the national award recognises country-wide excellence and the state award ensures every district is represented.

The state’s teaching cadre in outline. Bihar has a large, historically layered teaching workforce, including regular state teachers, teachers appointed under the Bihar Panchayat Elementary Teacher Appointment Rules at the local body level, contract teachers absorbed under successive rules, and aided-school and madrasa-board teachers. Salary rationalisation, service conditions and grievance redress across these cadres form the standing state policy agenda in education.

Bihar Relevance:

• Prelims: The Bihar State Teacher Award, 2026 was conferred on 38 teachers on 5 September 2026, one from each of the 38 districts.
• Prelims: 17 women teachers are among the awardees.
• Prelims: Bihar has 38 districts, following the reorganisation carried through in the 1970s and later.
• Prelims: National Teachers’ Awards are conferred by the President at Vigyan Bhawan, New Delhi; in 2026 48 teachers were honoured.
• Prelims: State teaching cadres in Bihar include panchayat teachers appointed under the Bihar Panchayat Elementary Teacher Appointment Rules.
• Mains: The design choice behind a one-per-district award and its effect on recognition beyond the state capital (GS2 education, public administration).

5. The Kosi Mechi Intra-State Link Project as the Standing File

Why in News: The Kosi Mechi Intra-State Link Project, cleared by the Cabinet Committee on Economic Affairs in March 2025 as the tenth project under PMKSY-AIBP, diverts part of the surplus water of the Kosi to the Mahananda basin by remodelling and extending the Eastern Kosi Main Canal for irrigation across Araria, Kishanganj, Purnia and Katihar. It remains the state’s standing water file this month, with its implementation directly shaping the medium-term flood and irrigation calculus in north Bihar.

Read the project precisely.

Why the project matters for flood management, not only irrigation. Diverting surplus flow from the Kosi during the peak monsoon should reduce the excess load on the middle Kosi, and by extension on the north Bihar rivers below. The scale of the diversion, and whether it is timed to the peak flood window rather than the crop demand window, is the design test that determines whether flood mitigation is actually delivered.

The constitutional and legal setting. Water is a subject in the State List (List II, Entry 17) of the Seventh Schedule, but inter-state rivers are covered by Entry 56 of the Union List to the extent regulated by Parliament. The Inter-State River Water Disputes Act, 1956 and the River Boards Act, 1956 are the standing statutory tools. For a project on a river that rises in Nepal, treaty-level cooperation is also engaged, and the Kosi Treaty of 1954, revised in 1966, sets the framework.

The Ramsar dimension. The Kanwar Taal in Begusarai district, one of Asia’s largest freshwater oxbow lakes and Bihar’s first Ramsar site since 2020 (officially Kabartal Wetland, Ramsar Site no. 2436, designated on 21 July 2020), sits on the Kosi-Ganga floodplain, and any change in the annual flood pulse affects its ecology.

Bihar Relevance:

• Prelims: The Kosi Mechi Intra-State Link Project diverts Kosi water to the Mahananda basin for irrigation across Araria, Kishanganj, Purnia and Katihar; it is the tenth project included under PMKSY-AIBP.
• Prelims: It creates an additional irrigation potential of 2,10,516 hectares in the Kharif season, at an estimated cost of Rs 6,282.32 crore with central assistance of Rs 3,652.56 crore.
• Prelims: Water is a State List (List II, Entry 17) subject; inter-state rivers fall under Entry 56 of the Union List.
• Prelims: The Inter-State River Water Disputes Act, 1956 is the standing statutory tool for inter-state river disputes.
• Prelims: The Kosi Treaty with Nepal was signed in 1954 and revised in 1966.
• Prelims: Kanwar Taal (Kabartal Wetland) in Begusarai, designated a Ramsar site on 21 July 2020, is Bihar’s first Ramsar site.
• Mains: Inter-basin transfer as flood mitigation, and the design test of timing the diversion to the peak flood window (GS3 environment, water resources).

Practice MCQs

1. The Ganga water level at Gandhi Ghat in Patna on 5 September 2026 crossed which of the following benchmarks?

a) The danger mark only, remaining below the previously recorded highest flood level b) The reserve level only, staying below both the danger and highest flood marks c) The previously recorded highest flood level of 50.52 metres, reaching 50.53 metres at 10 am d) The design flood level of the eastern embankment, staying at the danger mark

Answer: c

Explanation: The Ganga at Gandhi Ghat rose to 50.53 metres at 10 am on 5 September 2026, one centimetre above the previously recorded Highest Flood Level of 50.52 metres and 1.93 metres above the danger mark of 48.60 metres. A river above HFL and staying there tests the embankment and city defences at a benchmark they have not been asked to hold before, which is why the response was scaled up to 27 SDRF and 9 NDRF teams, 693 boats and 38 community kitchens, and around 10.26 lakh people across 11 districts including Patna, Bhojpur, Saran, Vaishali, Bhagalpur, Begusarai, Buxar, Samastipur, Munger, Katihar and Araria are affected.

2. On Teachers Day, 5 September 2026, the Bihar Chief Minister announced an AI ecosystem in school education in collaboration with:

a) IBM, Amazon Web Services and Zoho b) Microsoft, Google and Sarvam AI c) NVIDIA, OpenAI and TCS Research d) Meta, Anthropic and Wipro AI Labs

Answer: b

Explanation: Among the five Teachers Day announcements, the Chief Minister said an AI ecosystem in Bihar’s school education will be built in collaboration with Microsoft, Google and Sarvam AI, and that teachers will be trained in AI technologies. The other four announcements were the establishment of a state Teacher Training University, a separate pay scale for finance-deficit school teachers, efforts to set up a Banaras Hindu University centre in Bihar, and processing of pending salaries owed to Madrasa and Sanskrit Board teachers. Teachers Day marks the birth anniversary of Dr Sarvepalli Radhakrishnan, born 5 September 1888.

3. The National Disaster Response Force, which was deployed to Bihar’s flood districts along with the State Disaster Response Force, is constituted under which section of the Disaster Management Act, 2005?

a) Section 14 of the Act b) Section 25 of the Act c) Section 44 of the Act d) Section 62 of the Act

Answer: c

Explanation: The NDRF is constituted under Section 44 of the Disaster Management Act, 2005 and is deployed on state requisition. Section 14 provides for the State Disaster Management Authority chaired by the Chief Minister; Section 25 provides for the District Disaster Management Authority chaired by the District Magistrate. The National Disaster Management Authority at the apex is chaired by the Prime Minister. On 5 September 2026, 9 NDRF and 27 SDRF teams and 693 boats were deployed in Bihar’s flood districts, with 38 community kitchens serving the affected population of around 10.26 lakh across 11 districts.

4. The Kosi Mechi Intra-State Link Project, a standing water file for north Bihar, is designed to:

a) Divert surplus water from the Mahananda to the Kosi basin b) Divert surplus water from the Kosi to the Mahananda basin for irrigation in Araria, Kishanganj, Purnia and Katihar c) Divert water from the Ganga to the Kosi to relieve the Sorrow of Bihar d) Divert water from the Bagmati to the Gandak basin

Answer: b

Explanation: The project diverts part of the surplus water of the Kosi to the Mahananda basin by remodelling and extending the Eastern Kosi Main Canal, creating an additional irrigation potential of 2,10,516 hectares in the Kharif season across Araria, Kishanganj, Purnia and Katihar. The CCEA approved its inclusion as the tenth project under PMKSY-AIBP in March 2025, with central assistance of Rs 3,652.56 crore against an estimated cost of Rs 6,282.32 crore and completion targeted by March 2029. Diverting surplus Kosi flow in the peak monsoon should also reduce the excess load on the middle Kosi and by extension on the north Bihar rivers below, though whether the diversion is timed to the peak flood window rather than the crop demand window is the design test that decides whether flood mitigation is actually delivered. Water is a State List subject under Entry 17; inter-state rivers come under Entry 56 of the Union List.

5. Kanwar Taal, on the Kosi-Ganga floodplain, is significant because it is:

a) Bihar’s first Ramsar site, designated in July 2020 b) The largest saline lake in eastern India c) A crater lake formed by a Late Pleistocene meteorite impact d) A tectonic lake formed by faulting in the Himalayan foreland basin

Answer: a

Explanation: Kanwar Taal in Begusarai district, officially the Kabartal Wetland and one of Asia’s largest freshwater oxbow lakes, is Bihar’s first Ramsar site since 2020, designated on 21 July 2020 as Ramsar Site no. 2436. It is a wetland of international importance under the Ramsar Convention on Wetlands, adopted in 1971 at Ramsar, Iran, whose national authority in India is the Ministry of Environment, Forest and Climate Change. Because it sits on the Kosi-Ganga floodplain, changes to the annual flood pulse of the Kosi, including diversions under projects like the Kosi Mechi Intra-State Link Project, feed into its ecology, which makes it a live worked example for the trade-off between irrigation, flood management and wetland conservation.
