>I don't think mappers can know the maximum volume or capacity of a water reservoir or water basin, unless it is written on a public sign somewhere? We can map the surface area, but knowing the average depth or maximum depth is quite difficult, especially when it is not uniform. However for man_made=reservoir_covered and =storage_tank we have capacity=* (in cubic meters?) and content=water/sewage/etc.

>Currently for landuse=reservoir and water=reservoir this is some use of reservoir_type= -  https://wiki.openstreetmap.org/wiki/Key:reservoir_type - with values of water_storage, sewage, tailings, evaporator, tank, salt_pan, wastewater, slurry, irrigation, aquicultura, cooling, etc - though only the first 4 are at all common.

>basin=* is used with landuse=basin or water=basin to describe the form and function of the basin: 
>*  basin = infiltration  - An  infiltration basin  catches storm water and allows it to seep into an  aquifer .
>*  basin = detention  - A  detention basin  catches storm water and allows it to drain slowly into natural waterways.
>*  basin = retention  - A  retention basin  catches storm water and retains it, forming an artificial pond.

>And note that salt ponds (used to evaporate salt from sea-water) are tagged as  landuse = salt_pond
>Pools for swimming are  leisure = swimming_pool

>I don't see many combinations with usage=* or another tag that might describe how the reservoir or basin is used, so perhaps this could be proposed?
