Thanks.
Have been checking different sites and see that at least for pools they do minimum 20 cm and doble rebar 12mm in 20 cm grids.
Before have read steng 280 concrete as minium, so maybe 300 is needed.

It will also get some support from the land surrounding the dam, so opinions about 20/30 will be appreciated

I'm no structural engineer, so others may be able to advise more accurately. Land support around is certainly important however I think the issue will be that if the pond fills during rainy season but then empties during the dry the changes in pressure on the concrete can cause it to break. The guy building my Pool was a structural engineer in the UK prior to Thailand. If you like I can pm you his number. If you give him the dimensions I'm sure he can quickly work out steel and concrete requirements to ensure longevity.
