This is Meen Sarovar. Once, Shri Ghanshyam Maharaj came to this lake with His childhood companions to bathe. At that time, several fishermen had gathered together and were catching fish from the lake and piling them up along the bank.
As soon as the compassionate Shri Ghanshyam Maharaj, the ocean of mercy and embodiment of divine compassion, saw the fish struggling and dying, His tender heart was deeply moved. He immediately resolved in His mind:
“May all the fish come back to life.”
By the divine power of Shri Hari’s resolve, all the fish, both large and small, came back to life. They began jumping joyfully and returned to the waters of the lake.
Seeing this, the demon fishermen rushed toward Shri Bal Ghanshyam with the intention of attacking Him. However, at that very moment, they saw Shri Bal Ghanshyam manifest Himself in the formidable form of Yamraj, the Lord of Death.
Terrified, the fishermen begged Shri Bal Ghanshyam for forgiveness.
Shri Hari forgave them after making them take a vow to follow the principle of Ahimsa, or non-violence.
From that day onward, this lake came to be known as Meen Sarovar, meaning the Lake of Fish.
The lake is located to the south of the Janmasthan Temple. A sacred platform has been constructed on the bank of the lake, where the divine lotus footprints of Shri Hari have been installed.
