Gujarat’s water crisis is becoming a story of uneven security: the state’s overall reservoir storage has fallen sharply after a weak monsoon, even as the Sardar Sarovar reservoir holds slightly more water than it did a year ago. The contrast is significant because it shows how one large, relatively well-stocked reservoir can provide a measure of relief without reversing deterioration across the wider water system.
According to a report by Gujarat Samachar, water stored across Gujarat’s 206 reservoirs declined from 15,284.37 million cubic metres (MCM) in November 2025 to 10,103 MCM in November 2026. The reduction of 5,181.37 MCM represents a substantial year-on-year fall in the water available across the state’s reservoir network.
The decline is also visible in the state’s 17 major reservoirs. Their combined storage fell from 12,783.78 MCM to 8,840.65 MCM over the same period, a reduction of 3,943.13 MCM. These figures do not describe a single failing dam or one isolated district. They point to a broad weakening of water reserves across a system that includes reservoirs serving different regions and uses.
The rainfall comparison helps explain the change. Gujarat recorded 811.96 millimetres of rain in 2026 up to November, equivalent to 89.34% of the average, compared with 1,061.80 mm, or 119.13% of the average, during the corresponding period in 2025. The year-on-year difference was 249.84 mm, while the share of average rainfall fell by 29.79 percentage points, according to the report.
The report attributes the weaker monsoon to the impact of El Nino and identifies Devbhoomi Dwarka, Porbandar, Jamnagar and Kutch as the districts most affected by poor rainfall. Drought was declared in these four districts after the rainfall deficit created drought-like conditions. The immediate concern is not limited to the volume of water behind dams. Lower rainfall also affects agriculture and the replenishment of local water sources, although the supplied report does not provide crop-loss or groundwater data.
The most striking indicator of the shift is the distribution of reservoir storage. In November 2025, 151 reservoirs had more than 90% of their capacity filled. In November 2026, that number had fallen to 35. At the other end of the scale, reservoirs with less than 70% storage increased from 30 to 147. This change suggests that Gujarat’s water position is not merely lower in aggregate; storage is also spread across the system in a much weaker pattern.
That distinction matters for administration. A state-wide storage number can conceal major differences between basins, districts and supply systems. When more reservoirs move below higher storage thresholds, local authorities may have fewer operational buffers even if the state retains water elsewhere. The figures supplied in the report do not establish how much water is allocated to cities, irrigation or industry, but they do show that the margin available in many reservoirs is narrower than it was a year earlier.
Sardar Sarovar is the principal exception. Its storage increased from 9,369.82 MCM in November 2025 to 9,440.68 MCM in November 2026, a rise of 70.86 MCM. The reservoir’s comparatively strong position is described as the state’s main relief amid falling storage elsewhere. Its role in the present situation is therefore less about cancelling the wider deficit than about providing an important reserve within an otherwise weaker water landscape.
The difference between Sardar Sarovar and the rest of the reservoir network also highlights the importance of infrastructure scale and distribution. A large reservoir can improve the state’s aggregate position, but access to that water depends on the systems that move, treat and distribute it. The supplied report does not provide details of transfers, release schedules, municipal allocations or pipeline capacity, so it is not possible to determine from these figures alone how far Sardar Sarovar can offset shortages in specific districts or cities.
The condition of Ajwa Lake offers a more local and visible measure of the rainfall deficit. In 2025, after strong rainfall, its level reached 212.95 feet in September. Increased inflows led to all 62 gates being opened. In 2026, the lake did not reach a dangerous level even once, and its reported morning level was 208.57 feet. Gujarat Samachar said that the current level resembled the kind of level normally seen in February.
Ajwa’s situation is important because it connects the reservoir data to the functioning of an urban water source. The lake’s lower level does not, by itself, establish a current supply interruption or a specific restriction for residents. It does, however, show how a weak monsoon changes the seasonal cycle of a water body that would ordinarily have gained substantially during the rains. The difference between a reservoir filling rapidly in September and remaining below a high-water threshold throughout the season changes the amount of flexibility available to water managers.
The state’s response is consequently operating on two levels. At the district level, drought declarations in Devbhoomi Dwarka, Porbandar, Jamnagar and Kutch recognise the severity of local rainfall conditions. At the system level, the storage position of 206 reservoirs and the relative strength of Sardar Sarovar determine how much water can be managed across regions. These are related but separate administrative questions: a state may retain a major reserve while individual districts still face weak local recharge and stressed supplies.
The evidence also shows why rainfall averages alone are insufficient to describe water security. Gujarat’s rainfall in 2026 was below average, but the more operationally relevant outcome is how that rainfall translated into reservoir storage. The fall from 151 reservoirs above 90% capacity to 35, alongside the rise in reservoirs below 70% from 30 to 147, indicates that the system absorbed the weaker monsoon unevenly and with a much smaller cushion in most reservoirs.
For cities and towns, the next question is how these storage conditions will be converted into supply decisions. That would include the timing of releases, the priority assigned to drinking water, the condition of distribution infrastructure and the management of demand through the drier months. None of those operational details is provided in the source material, and they should not be inferred from the storage figures alone. The data nevertheless establish a clear administrative challenge: water managers must coordinate a stronger central reserve with weaker local reservoirs and different district-level conditions.
The agricultural implications are also direct. The report links the rainfall deficit to concern over farming and available water, but it does not quantify the affected area, crop losses or irrigation demand. That limitation is important. Reservoir storage provides evidence of reduced water availability, not a complete assessment of the economic impact. A fuller evaluation would require district-wise rainfall, crop, groundwater, irrigation and allocation data.
What the available numbers confirm is a sharp deterioration in Gujarat’s year-on-year water buffer. Total storage is down by 5,181.37 MCM, storage in the 17 major reservoirs is down by 3,943.13 MCM, and the number of reservoirs with very high storage has fallen dramatically. Sardar Sarovar’s additional 70.86 MCM provides relief, but it does not erase the broad-based decline elsewhere.
The developments that deserve monitoring are the state’s release and allocation decisions, the condition of reservoirs through the dry season, and the implementation of drought-related measures in the four declared districts. More detailed official data will also be needed to establish how the storage imbalance affects municipal water supply, irrigation and local water bodies. For now, Gujarat’s reservoir figures point to a system with one major source of resilience but a much thinner margin across the rest of the network.
