who built the sudarshan lake in the saurashtra region
History of Gujarat Chandragupta Maurya of Maurya dynasty conquered a number of earlier states of Gujarat circa 300 BC. Pushyagupta, a Vaishya, was appointed Governor of Saurashtra by the Mauryan regime. He ruled (322 BC to 294 BC) Girinagar (present Junagadh) and built a dam on the Sudarshan lake. Emperor Ashoka, the grandson of Chandragupta Maurya, not only ordered engraving of his famous edicts on the rock at Junagadh, but asked his Governor Tusherpha to take out canals from the lake where an earlier Mauryan Governor had built a dam. Between the decline of the Mauryan power and Saurashtra coming under the sway of Samprati Mauryas of Ujjain, there was a Greek incursion into Gujarat led by Demetrius.In the first half of the first century A.D. there is the story of a merchant of King Gondaphares landing in Gujarat with Apostle Thomas.The incident of the cup-bearer killed by a lion might indicate that the port city described is in Gujarat.[13][14]
Lake Okeechobee The floor of the lake is a limestone basin, with a maximum depth of 13 feet (4 m). Its water is somewhat murky from runoff from surrounding farmlands. The Army Corps of Engineers targets keeping the surface of the lake between 12.5 and 15.5 feet (4 and 5 m) above sea level.[26] The lake is enclosed by a 40 feet (12 m) high Herbert Hoover Dike built by the U.S. Army Corps of Engineers after a hurricane in 1928 breached the old dike, flooding surrounding communities and claiming at least 2,500 lives.[27] Water flows into Lake Okeechobee from several sources, including the Kissimmee River, Fisheating Creek, Lake Istokpoga, Taylor Creek, and smaller sources such as Nubbin Slough and Nicodemus Slough.[28][29] The Kissimmee River is the largest source, providing more than 60% of the water flowing into Lake Okeechobee.[30][31] Fisheating Creek is the second largest source for the lake, with about 9% of the total inflow.[29] Prior to the 20th century, Lake Istokpoga was connected to the Kissimee River by Istokpoga Creek, but during the rainy season Lake Istokpoga overflowed, with the water flowing in a 40 km wide sheet across the Indian Prairie into Lake Okeechobee.[32] Today Lake Istokpoga drains into Lake Okeechobee through several canals that drain the Indian Prairie, and into the Kissimmee River through a canal that has replaced Istokpoga Creek.[33] Historically, outflow from the lake was by sheet flow over the Everglades, but most of the outflow has been diverted to dredged canals connecting to coastal rivers, such as the Miami Canal to the Miami River, the New River on the east, and the Caloosahatchee River (via the Caloosahatchee Canal and Lake Hicpochee) on the southwest.
