It is believed that there will be many less aquifers if you make sure that there are no oceans (set ''Elevation Weighted Ranges'' 0-20 and 20-40 to 0/None to ensure that the minimum elevation is above 100, and set ''Minimum Ocean Edges'' to 0/None). High drainage will also reduce aquifers, but with the side effect of reducing [[lake]]s and [[swamp]]s. Also, widespread high draining might lead to too many worlds being [[World generation#Rejects|rejected]]. | It is believed that there will be many less aquifers if you make sure that there are no oceans (set ''Elevation Weighted Ranges'' 0-20 and 20-40 to 0/None to ensure that the minimum elevation is above 100, and set ''Minimum Ocean Edges'' to 0/None).
