Located in the centre of West Caicos, Lake Catherine is a very shallow 430 acre (174 hectare) saline wetland nature reserve. This site is a highly-important nesting region for wading birds, as well as a prime habitat for flamingos.
As is the case with many of the interior ponds in the Turks and Caicos, Lake Catherine has a higher salinity content than the surrounding ocean due to natural evaporation.
Lake Catherine and the adjacent shallow and extensive ponds to the east are among the finest birdwatching regions in the Turks and Caicos.
A little-known fact is that Lake Catherine has an extensive underwater cave system. Found on the western side of the nature reserve, this cave maintains the water level and tidal change of Lake Catherine, much like the Boiling Hole feature on South Caicos.
Initially explored by divers from the Caicos Cave Project in 2000, this system was found to have over 675 feet (200m) of passage, with smaller fissures that continued. The depth of much of the cave system was around 50 feet (18m), which is actually a bit shallower than similar systems in the country.
Tidal movements were said to be quite significant, which severely limited explorations and affects safety.
Due to the cave’s location at less than half a mile from the edge of the Caicos plateau and deep ocean water, this system is probably the most-likely cave in the Turks and Caicos to have a clear subterranean passage from an interior pond to the open ocean.
Although outside of the Lake Catherine Nature Reserve, the southern Greenlands region of West Caicos also supports many submerged caves, albeit much less extensive features. The majority of these are collapsed water lens caves.
A manmade loose rock causeway, built during the sisal planting days at the end of the 1800s, dissects Lake Catherine and connects the abandoned and ruined Yankee Town to the east coast of West Caicos.
Constructed to support a small gauge donkey cart railroad that was used to transport the sisal leaf harvests, stamped steel sleepers and the occasional rail can still be seen.
A low rail cut was made through two lows limestone hills in the centre of the island; definitely an interesting feature.
Lake Catherine is a protected nature reserve and as such has is governed by certain guidelines and regulations.
It is illegal to harm, disturb or interfere with any wildlife in the nature reserve.
It is illegal to take and natural item or historical artefact from the protected area.
Open fires and camping is prohibited without specific written approval from the appropriate government department.
As is the case throughout the Turks and Caicos, littering is punishable by fines and/or imprisonment.
