turlough (lake)









































a turlough, or turlach, is a type of disappearing lake found mostly in limestone areas of ireland, west of the river shannon. the name comes from the irish "tur", meaning "dry", with the suffix "-lach", meaning "a place" (in an abstract sense). the "-lach" suffix is often mistakenly spelled and/or thought to refer to the word "loch", the irish, scottish gaelic and scots word for "lake". the landforms are found in irish karst (exposed limestone) areas.

the disappearing lake area in pleasant valley area is a geologically significant feature of the area. this lake is located on an area of karst geology, which is typified by a cavernous underground landscape. through the use of water tracer dyes, proett (1978) identified a distinct hydrologic connection between disappearing lake and its eventual outlet into nine mile creek at marcellus falls. although disappearing lake is a springtime phenomenon, groundwater outlets at marcellus falls have been observed to be active as late as october. these groundwater flows serve as a significant input of cold, nutrient-rich waters during summer months. it is notable that water flowing through karst systems is sensitive to change. this is because water flows too quickly through such cavernous networks to allow pollutants to be removed from the system. in particular, white noted that nitrates are not broken down as they flow through karst drainages. thus nitrate inputs into the groundwater system at pleasant valley may be expected to be similar to the outputs into nine mile creek at marcellus falls. from this perspective, sources of road salt, agricultural runoff, and "e. coli" are all concerns for upland areas associated with disappearing lake area. this is because they may eventually alter water quality in nine mile creek below marcellus falls.
