DJI Mavic Pro - Mine lake in Richmond, Texas after hurricane Harvey's 52 inches of rainfall

A mine with a crater of 1,000ft radius and a conservative average depth of 20 feet, or 63 million cubic feet is filled up with rain water in less than a week after hurricane Harvey's massive 52in rainfall. The Brazos river in Richmond reached a crest level of 55.2ft breaking the old record of 54.7ft. To fill the crater required 472.5 million gallons of water since a cubic foot is equivalent to 7.5 gallons. An average size pool has 25,000 gallons so this crater is approximately the size of 15,000 pools and it filled up in less than a week !
