Uttar Pradesh's Irrigation Department reunited three Ganga river streams at the Sangam, creating 22 hectares of bathing space for the 2025 Mahakumbh. This reverses the river's natural course alteration, simplifying pilgrim access and improving water purity. Dredging, despite initial challenges with strong currents, enabled the merging, centralizing bathing for the expected 40 crore devotees.
