These are to control rain water runoff during storms and consist of a pond surrounded by an embankment with a controlled release structure to slow down drainage of the water to the river system. The relevant features might be ·Low or normal water level of pond ·High water level or top of embankment ·Land use/vegetation between low/high water marks is water tolerant/marsh plants ·Structures for water input and output – often brickwork and filter screens round a pipe. Has anyone any experience of mapping and tagging such a structure? Are there any examples of where this has been done?These are common where I live. (We get lots of rain from October to June) I map them as landuse=basin, basin=* based on how they are designed. See https://wiki.openstreetmap.org/wiki/Key:basin for more info.
I have done 2 as detention ponds .. http://www.openstreetmap.org/way/282846991
