The Lower Bhavani Dam, commonly known as Bhavanisagar Dam and Reservoir, is situated in the Erode district on the Bhavani River. The dam, which is the second biggest in Tamil Nadu, supplies water to the Lower Bhavani Project Canal. Additionally, it is the world's second-biggest earthen dam (the largest is in Russia). The earthen bund itself is eight kilometers long, measured from Zero Point. Between 1948 and 1955, during the post-independence era, the Dam was built. The dam's construction cost twenty-one billion rupees. It is a dam with multiple uses. It is used to supply drinking water, produce energy, store water for agriculture, manage flooding, and prevent silt buildup in rivers downstream.

    The water level of Bavani Sagar dam has drastically decreased due to the heat. When the water level dropped in 2018, these temples were seen. After that, the water level did not drop for six years, making the temples invisible. With the water level now at 46 feet, the Madhavaraya Perumal temple and Danaikan Fort are fully visible. 
   After the dam's water level dropped, the 600-year-old Danaikkan Fort, Madhavaraya Perumal, Someswarar, and Mangalambhikai Temples in the Bhavanisagar Dam Reservoir area of Erode District were visible. Before the dam was built, the local population used these temples as places of prayer. Following the commencement of dam building, the residents of the reservoir area relocated to the Bhavanisagar area. Consecrated by establishing a temple on the banks of the Kizbhavani waterway at Bhavanisagar, they brought the idols from the shrine. 
   The temples and halls made completely of stone were drowned in the dam's water after construction was finished in 1955. It started to break down over time. The Danaikkankottai Madhavaraya Perumal Temple, Someswarar, and Mangalamphikai Temples are visible from the outside when the dam's water level drops below fifty feet out of a total of 105 feet.
   The reservoir region and the Bhavanisagar Dam are off-limits to the general public due to their status as protected areas.  Here, a few people surreptitiously visited the Madhavaraya Perumal temple, recorded a video, and shared it on social media. A few people visit the area specifically to consume alcohol. Officials from the Water Resources Department have since posted a warning banner in the vicinity. Owners of ferries are not permitted to transport guests to Danaikkankottai Fort via Parisal or motorboat. Strict legal action will be taken against them, they have warned. Many people in the district were afraid that there would be a lack of drinking water as a result of the dam's water level dropping.
   However, even though we are unable to attend, we may preserve this as a reminder of our ancestors and learn how old the temple is. However, I sincerely hope they will allow us so we can view it from some distance away.
