Canal Water and the Tail-End Village
A distributary of a canal system in south Bihar serves 11 villages along its 19 km length. The designed discharge is 42 cusecs, but measured flow at the head is 34 cusecs in the rabi season. Farmers in the first 6 km irrigate freely, some growing water-intensive crops; farmers in the last three villages report that water reaches them for barely four days in a fortnight. The canal runs on a rotation (warabandi) schedule that is displayed on a board at the head regulator but nowhere else. A farmer from the tail village has filed a complaint alleging that the outlet of a head-reach village was widened illegally. You chair the canal committee meeting where both groups are present and tempers are high.
1. Before deciding anything, what must you establish, and how would you establish it without assuming the complaint is true?
Read the worked answer
The complaint has two possible causes that look identical from the tail: illegal widening at the head, or simply insufficient supply plus free use upstream. The answer must distinguish them before acting.
Measure the outlets. Each outlet has a designed discharge and a fixed crest level. A physical measurement of the throat width and the water level at each of the head-reach outlets, compared with the design register, settles the widening allegation objectively. If outlets are wider than sanctioned, that is a finding; if they match, the allegation fails and the cause lies elsewhere.
Measure the loss along the length. Gauging at the head, at mid-length and at the tail tells you whether water is being lost to seepage and unauthorised pumping or is being consumed legitimately upstream. A 42-to-34 cusec shortfall at the head is itself a supply fact that no farmer caused.
Check the rotation is actually being run. A schedule displayed only at the head regulator is not a schedule for the tail. Verify whether the gauge readings and gate operations match the published rotation, because a head-reach farmer irrigating on a tail village's turn is a violation that leaves no physical trace.
Record before acting. Measurements with date, time and signature of both a head-reach and a tail representative prevent the finding from being dismissed as partisan. Deciding first and measuring later is the failure mode here.
2. The measurements show one head-reach outlet is 20 per cent wider than sanctioned, but the total excess water it can carry explains only a part of the tail's shortfall. How do you allocate responsibility and what do you order?
Read the worked answer
Responsibility is shared, and the order should reflect that proportion rather than picking one culprit.
The widened outlet is an unauthorised structure. The order is to restore it to sanctioned dimensions at the landholder's cost, and to report the matter for such penalty as the canal rules provide. This is a clear violation and must be corrected.
The unexplained remainder points to the shortfall at the head (42 to 34 cusecs) and to losses along the length. Neither is the tail farmers' fault, and neither is cured by punishing the head-reach farmer. The canal administration must address it through lining of the worst seepage reaches, scheduling of supply, and enforcement against unauthorised pumping.
The free use upstream is partly a rule-enforcement problem: if head-reach farmers irrigate outside their turn, the rotation is being violated even where no structure is widened. The remedy is turn-wise patrolling and a log at each outlet.
What not to do: do not promise the tail full supply that the head discharge cannot deliver. Promising 42 cusecs when 34 arrives guarantees a repeat confrontation. State the actual availability and divide the shortfall transparently, for example by proportional cuts across the rotation.
The principle is proportionate, evidence-based allocation: penalise the proven violation, and treat the physical shortfall as a common problem to be managed, not a fault to be assigned.
3. Design a communication and monitoring arrangement so that the next dispute is resolved before it becomes a confrontation.
Read the worked answer
The dispute grew because information was held at one end of a 19 km canal. Four changes address that.
Publish the rotation where it operates. Display the warabandi schedule at every village outlet, in the local language, with the turn timings of each village. A farmer who can read his own turn has no need to allege theft.
Create a joint gauge log. A register at the head and tail regulators, signed daily by the outlet operator and a rotating farmer representative, makes flow visible to both ends. The tail's four-days-in-a-fortnight complaint becomes a number that either confirms or refutes itself.
Institutionalise the committee. The canal committee should meet before the rabi season, not during a crisis, with a standing agenda: measured availability, rotation compliance, and pending violations. Decisions minuted and circulated to all 11 villages.
Escalation path with time limits. A complaint about an outlet should be measured within a fixed period, say seven days, and the measurement shared with the complainant. Delay is what converts a grievance into a confrontation.
The test: would the tail farmer know, on any given day, whether he is being served his due, without having to travel 19 km to read a board?
