This positioning places the reservoir within the broader geographical framework of , where it functions as a key freshwater body in a semi-arid to zone characterized by seasonal monsoons. The site lies approximately 26 kilometers west of Indore city, the largest urban center in the region, and is located near Hatod village along the Indore-Depalpur road, facilitating relatively easy access for local communities and visitors. This proximity to Indore underscores its integration into the district's hydrological and infrastructural network, while the reservoir's placement on the Gambhir River—a tributary in the larger Chambal River system—highlights its role in managing seasonal water flows from upstream areas. As a freshwater in the Gambhir River basin, Yashwant Sagar covers an area of about 822.9 hectares at full capacity, serving as a vital impoundment that captures runoff from surrounding agricultural and forested catchments. Its environmental setting includes gently undulating plains typical of the Plateau, at an elevation of 556 meters above , contributing to its ecological significance as a water source amid variable rainfall patterns averaging ~1,000 mm annually in the district.

Surrounding Landscape

Yashwant Sagar is enveloped by flat to gently undulating terrain typical of the agro-ecological zone, dominated by expansive open fields and agricultural lands with scattered scrub vegetation. The soil in the surrounding area is predominantly black cotton soil, a fine-grained, lime-rich derived from Deccan Trap basalts. The reservoir lies within the basin of the Gambhir River, a of the Shipra River (itself a of the Chambal River in the Ganges system), covering a of approximately 2,650 hectares characterized by agricultural dominance and seasonal water flows. Nearby human settlements include Hatod and Gurda Khedi villages, directly adjacent to the site, with the reservoir situated about 26 kilometers west of the urban area, falling under the jurisdiction of the for administrative purposes. The landscape experiences pronounced seasonal variations under a , with hot summers reaching up to 40°C, mild winters around 3°C, and the southwest delivering over 91% of the annual 1,000 mm rainfall between and , often leading to flooding that temporarily alters the surrounding plains and enhances hydrological connectivity. This influence periodically swells the Gambhir River, impacting the flat agricultural expanses through inundation and deposition. The plays a key role in irrigating these farmlands, sustaining crops such as wheat, corn, pulses, and cash crops across the open fields.

History

Construction

Yashwant Sagar was constructed in 1930 by Yashwant Rao Holkar II, the Maharaja of the princely state of Indore during the British Raj. As ruler of the Holkar dynasty, he initiated the project to address water needs in the growing urban center of Indore and its surrounding agricultural lands. The reservoir was created by building a dam across the Gambhir River, a tributary in the Chambal River basin, approximately 26 kilometers west of Indore near Hatod village. The dam formed a man-made freshwater reservoir designed primarily as a multipurpose facility for irrigation to support regional farming and for supplying drinking water to bolster Indore's population and economic expansion. At its inception, the reservoir was engineered with an initial storage capacity of 16.99 million cubic meters (MCM) at full reservoir level, achieving a maximum depth of 15-16 meters to ensure reliable seasonal water retention.

Ramsar Designation

Yashwant Sagar was designated as a wetland of international importance under the Ramsar Convention on January 7, 2022, receiving site number 2495. This recognition underscores its role as a key freshwater reservoir originally constructed in 1930 for irrigation and drinking water supply to the Indore region. The site meets Ramsar Criterion 2 by supporting , notably serving as a stronghold for the (Grus antigone), and Criterion 5 due to its regular congregation of over 20,000 waterbirds. It also provides essential ecological services, including through maintenance of the hydrological regime, alongside , , and fish culture that benefit the surrounding . These attributes highlight its importance as an Important Bird and Biodiversity Area (IBA) in the region. As one of India's over 80 Ramsar sites, Yashwant Sagar exemplifies efforts in adjacent to urban centers like , promoting biodiversity protection and sustainable resource use. The wetland's management involves the in coordination with the Madhya Pradesh State Wetland Authority and the Environmental Planning & Coordination Organisation (EPCO).

Design and Specifications

Dam Structure

Yashwant Sagar Dam is a man-made barrier constructed across the Gambhir River in the of , . Erected in 1939 under the direction of , the ruler of the Holkar State of , the dam functions as the core engineering component that impounds river flow to form the Yashwant Sagar , providing essential storage for purposes. The structure incorporates purpose-built features such as spillways and to facilitate flood control by regulating the release of surplus during periods of high inflow. These mechanisms allow for controlled overflow, preventing downstream flooding; for instance, in September 2023, four were opened in response to rising levels from rains, and similarly in August 2024, one gate was activated upon reaching full reservoir capacity. Maintenance of the dam is handled by the Indore Municipal Corporation, which conducts routine inspections and repairs to maintain structural integrity and operational reliability. The dam's design ensures the formation of a stable reservoir body, supporting its primary role in regional water management.

Reservoir Features

Yashwant Sagar is a freshwater reservoir formed by the Yashwant Sagar Dam on the Gambhir River, with a surface area of 822.9 hectares at full reservoir level. The reservoir's submergence area spans 822 hectares, encompassing shallow backwaters and islands that emerge during seasonal water level fluctuations. The storage capacity reaches 16.99 million cubic meters (MCM) at full level, supporting stable water retention in the Gambhir River basin. Hydrologically, the features maximum depths of 15-16 meters, with extensive shallow areas and vast reed beds in the backwaters that vary seasonally due to inflows and water recession. Average depths fluctuate with the water regime, typically permanent but receding to expose more shallows outside the June-September period, when 91.2% of the annual 1000 mm rainfall occurs. Water quality in the reservoir is characteristic of freshwater systems, with temperatures ranging from 13°C in winter to 32°C in summer, though it is influenced by agricultural runoff from the predominantly farming-based catchment area of 2,650 hectares, where crops like wheat, soybean, corn, pulses, and vegetables are cultivated.

Uses and Management

Water Supply and Irrigation

Yashwant Sagar serves as a vital source for irrigation in the Indore district of Madhya Pradesh, supporting agricultural activities across its approximately 2,650-hectare catchment area. The reservoir provides water primarily for irrigating farmlands in the surrounding regions, enabling the cultivation of key crops such as wheat, soybeans, corn, pulses, and vegetables. This irrigation support is facilitated through controlled releases, ensuring seasonal water distribution to enhance farming reliability in an area prone to variable rainfall. In addition to irrigation, Yashwant Sagar is a major provider of to city, supplying up to 45 million liters per day (MLD) through a dedicated pipeline system connected to the Deodharan Water Treatment Plant. from the , which has a storage capacity of 16.99 million cubic meters, is treated and distributed to meet urban domestic demands, forming one of the city's oldest and supplementary sources alongside the . The oversees the abstraction and distribution for potable use, in coordination with the Madhya Pradesh State Wetland Authority for overall site management, maintaining quality standards to serve the growing population. The reservoir's contributions to and have significant economic implications for the region, bolstering and supporting the livelihoods of local farmers dependent on stable water access. By facilitating higher crop yields in , Yashwant Sagar helps sustain and contributes to the area's overall through enhanced rural and output in staple and cash crops.

Fisheries and Recreation

Yashwant Sagar serves as an important site for commercial fisheries, supporting aquaculture and fishing activities that supply local markets in the Indore region. The reservoir sustains 39 fish species, including major carps such as Catla catla and Cirrhina mrigala, minor carps like Labeo calbasu and Labeo bata, catfishes including Wallago attu and Mystus seenghala, murrels such as Channa marulius, and the exotic Cyprinus carpio. These populations benefit from the wetland's diverse aquatic habitat, which provides essential breeding and foraging grounds. Commercial fish culture has been introduced relatively recently, though operations remain unorganized, with challenges like the absence of storage facilities leading to immediate sales of catches after using gill nets and hooks. Beyond fisheries, Yashwant Sagar offers recreational opportunities that draw visitors seeking leisure amid its scenic . As an Important Bird and Biodiversity Area (IBA), it is a premier destination, hosting 239 bird species, including the vulnerable (Grus antigone), and serving as a key stopover for migratory waterfowl during winter months. excursions allow visitors to explore the reservoir's backwaters, while picnicking spots along the shores provide areas for relaxation and family outings, particularly in the lush post-monsoon season when water levels enhance the site's appeal. The reservoir's proximity to , about 26 kilometers away, boosts its tourism potential, attracting thousands of day trippers annually for these low-impact activities that contribute to the local economy without compromising the site's ecological integrity. Efforts to develop , such as improved access paths and viewing platforms, further promote sustainable while highlighting Yashwant Sagar's role as a multifaceted resource.

Ecology and Conservation

Biodiversity

Yashwant Sagar, a freshwater reservoir in , , supports a rich avifauna with 239 bird species recorded, including several of conservation concern. Among these, the vulnerable (Antigone antigone) maintains a significant population, with approximately 28 individuals observed as of 2025, though this represents a 68% decline since 2021, making the site a key but increasingly threatened stronghold for this species. The vulnerable Ferruginous Pochard ( nyroca) is also present in notable numbers. These waterbirds, along with waders and other migratory species, utilize the wetland's islands and receding water edges for roosting, nesting, and foraging. The aquatic ecosystem hosts 39 fish species across six orders and ten families, contributing to the reservoir's ecological diversity. Notable species include Common Carp (Cyprinus carpio), Rohu (Labeo rohita), and the vulnerable Wallago Catfish (Wallago attu), which rely on the wetland for feeding and spawning grounds. Shallow reed beds in the reservoir further support waders and waterfowl by providing shelter and foraging opportunities for both resident and visiting avifauna. Flora at Yashwant Sagar features emergent vegetation such as reeds and aquatic plants, including lotus (Nelumbo nucifera) in cultivated patches. These form dense stands in shallower zones, enhancing complexity. The site's primary types encompass edges characterized by open fields and agricultural margins, alongside expansive open water areas that serve as core zones for aquatic species. Its designation as a underscores the importance of these habitats for conservation.

Threats and Protection

Yashwant Sagar faces several environmental threats that impact its ecological integrity as a Ramsar-designated wetland. Water abstraction for urban and agricultural use has a medium-level impact on water levels within the site. Invasive non-native species, such as the water hyacinth Eichhornia crassipes, also pose a medium threat by altering habitats and reducing biodiversity. Pollution from agricultural runoff and urban household sewage contributes to water quality degradation at a medium intensity, exacerbating risks to species like the vulnerable Sarus Crane (Antigone antigone), which nests in the wetland. Recent surveys as of 2025 highlight additional pressures including excessive fishing and net entanglement, soil digging for vegetable farming, tourism disturbances from motorized boats, and potential illegal poaching, contributing to a noted decline in overall bird populations. Conservation efforts include ongoing monitoring of the site as an (IBA) to track bird populations and ecological health. Community awareness programs, led by organizations like the , engage local residents through interactive sessions to highlight the wetland's importance for livelihoods such as fisheries and eco-tourism. The manages day-to-day operations, supporting these initiatives. Despite its Ramsar designation, surveys indicate limited effectiveness in halting declines, with calls for prioritizing conservation, , and curbing harmful activities. Legal protections stem from its designation as a in January 2022, obligating to maintain its ecological character under the . At the state level, the enforces the Wetlands (Conservation and Management) Rules, 2017, through an order issued on March 16, 2022, which regulates activities like encroachments and pollution in notified wetlands including Yashwant Sagar, though implementation remains partial. Future initiatives focus on control measures to improve and restoration through , as outlined in site plans being prepared by the government. Real-time monitoring for and encroachments is also being implemented to enhance protection.
