Inflows rise in Nagavali, Vamsadhara as monsoon rains aid water supply
Rivers in Srikakulam and Vizianagaram districts saw increased flow after a prolonged dry spell linked to El Niño. Key reservoirs and barrages recorded significant inflows, triggering irrigation releases and raising drinking-water prospects amid groundwater depletion.
Key takeaways
- Rivers in Srikakulam and Vizianagaram saw renewed water inflows after a prolonged dry period linked to El Niño.
- Gotta barrage on Vamsadhara and Itipudi reservoir on Gosthani reported major inflows around 15,000 cusecs, enabling irrigation releases.
- Madduvalasa reservoir received water and discharged for irrigation, while rainfall deficit prior to the inflows underscores the significance of these developments for crops and drinking water.
What Happened
Rivers in northern coastal Andhra Pradesh, notably the Nagavali and Vamsadhara, experienced renewed water discharge after a period of low flow spanning about two and a half months. This uptick followed recent rainfall in catchment areas along the Andhra-Odisha border, contributing to stronger water levels in several water bodies and canals used for farming and drinking water.
Specific inflows and releases include:
- The Gotta barrage on the Vamsadhara received 15,647 cusecs of water, with an equal volume released for irrigation purposes.
- The Thotapalli project on the Nagavali reported adequate water due to ongoing inflows from its catchment.
- In the Gosthani river system, the Itipudi reservoir near Vishakhapatnam (Gosthani) registered 15,111 cusecs of inflow on the same day.
- Irrigation authorities discharged 12,700 cusecs from the Itipudi- Gosthani system to cropland in the districts of Vizianagaram (Gantyada, Gajapathinagaram, Jami and adjacent areas).
- At the Madduvalasa reservoir in the Rajam Assembly constituency of Vizianagaram district, 1,342 cusecs of water were received, with 710 cusecs released for irrigation needs.
Officials note that rainfall was deficient across 24 mandals in June, July, and early August, highlighting the relief provided by the inflows as farmers and authorities anticipate better water availability for crops in the coming months.
Visakhapatnam and surrounding districts reported that the Nagavali was visibly full at Srikakulam city, a key source for local drinking water. The administration indicated an emphasis on meeting drinking-water requirements amid groundwater depletion linked to the extended dry spell and El Niño conditions. The Vizianagaram district collector reiterated the need to balance agricultural water supply with drinking-water demands as water levels rise modestly following recent rainfall.
Why It Matters
The renewed water flow directly affects irrigation and crop prospects after a period of scarcity. Officials are using the renewed inflows both to sustain standing crops and to replenish drinking-water supplies for communities reliant on river water and reservoirs. The situation underscores the sensitivity of farming communities to rainfall patterns influenced by El Niño and the importance of reservoir management in mitigating groundwater depletion.
Farmers and local authorities are hopeful that the current water levels, aided by sustained inflows and scheduled releases, will translate into improved agricultural prospects in the ensuing months. The rainfall rebound, if sustained, could lessen the immediate stress on irrigation infrastructure and drinking-water availability in the region.
Background
Rains in catchment areas along the Andhra-Odisha border have historically influenced inflows to rivers like Nagavali and Vamsadhara. El Niño factors contributed to a prior period of reduced rainfall, leading to low river flows and depleted groundwater. The latest data issued by irrigation officials records notable inflows and corresponding releases intended to support crop irrigation and drinking-water supply.
Key Facts
- Date of observation: August 25, 2026.
- Gotta barrage (Vamsadhara) inflow and release: 15,647 cusecs.
- Itipudi reservoir (Gosthani) inflow: 15,111 cusecs.
- Irrigation discharge from Itipudi system: 12,700 cusecs.
- Madduvalasa reservoir inflow: 1,342 cusecs; irrigation discharge: 710 cusecs.
- Areas with recent good inflows include Gantyada, Gajapathinagaram, Jami and surrounding Vizianagaram areas.
- Rainfall was deficit across 24 mandals in June, July, and early August 2026.
- Nagavali was reported to be full at Srikakulam, supporting drinking-water needs.
- Statements from Vizianagaram district administration emphasized meeting farmers’ needs and drinking-water requirements amid groundwater depletion due to El Niño.
What Happens Next
Officials indicated ongoing attention to balancing crop irrigation with drinking-water needs as water levels rise. The expectation is that renewed inflows will sustain reservoir releases for irrigation and support water supply for communities, potentially easing groundwater stress if rainfall remains favorable in the coming weeks.
