Flood Entrance Pot (sometimes known as Flood Exit Pot) is one of the entrances to the Gaping Gill cave system located about 300 metres (330 yd) south of Gaping Gill Main Shaft. It was the first alternative entrance into the main system to be explored, and it is now a popular entrance into the system, with a fine 38-metre (125 ft) pitch landing in Gaping Gill's South-East Passage. It lies within the designated Ingleborough Site of Special Scientific Interest.
A climb down in the small shakehole soon leads to a tight 15-metre (49 ft) pitch. At the bottom the passage passes beneath the aven where Wade's Entrance joins, and after a further 80 metres (260 ft) it goes round a series of bends to where the last pitch of OBJ Hole enters. There is a chamber after a further 30 metres (98 ft) where a small stream enters from an inlet passage. Downstream a succession of climbs and a 14-metre (46 ft) pitch reach the main pitch of 77 metres (253 ft). South-East Passage in Gaping Gill may be stepped into at the −38 metres (−125 ft) level, but the shaft continues in two stages as South-East Pot to a 29-metre (95 ft) deep pool. This is a window into a large underwater passage, and dye tests have shown that the water from Gaping Gill Main Chamber and from Stream Passage Pot flow through this passage. Above the final shaft there is a tight passage, Horrocks-Stearn Crawl, which connects to Bar Pot above its main pitch.
Wade's Entrance (54°08′50″N 2°22′57″W / 54.147100°N 2.382525°W) is an alternative entrance 30 metres (98 ft) north-east of Flood Entrance Pot. A 3-metre (10 ft) climb down lands at the top of a 23-metre (75 ft) pitch which drops into the passage a few metres downstream of the Flood Entrance Pot entrance pitch. This is a very much easier than the original entrance, and is the voie normale.
