From what I know about plants, the leaves have stoma in the bottom layer. Stoma are holes, through which excess water moves out of during transpiration The weather, humidity, water potential gradients and temperature all affect transpiration rates.
In water lily the leaves remain floating on water, therefore, the lower surface of leaf which remains in contact with water is without stomata . The upper leaf surface has stomata for gaseous exchange.
Lower surface to gather CO2 and absorb water vapour.
In monocot leaves stomatal distribution is almost evenly on the upper and lower surface of the leaf. In herbacious dicot stomata is distributed more on the lower surface than the upper surface. Lastly in woody dicot there is not stomatal distribution on upper surface but great distribution on lower surface of leaves.
On a dorsi-ventral leaf most of the stomata are found on the lower side of the leaf, that remains away from sunlight. On an iso-bilateral leaf stomata are present on both the sides, upper as well as lower.
It is found on the top because the bottom is submerged in water.
Stomata are found on the lower side of the leave because they are the gateway for gas exchange, and gas surrounds the plant on all sides. If they are found more commonly on the bottom side of leaves, it is likely because the direct sunlight on superior leaf surfaces would cause increased evaporation via stomata, which i snot good for the plant.
Stomata are found in the lower skin. They help make food by letting carbon dioxide pass through the leaf and oxygen and water vapour to pass out.

Stomata that can help plants to exchange gases.
Stomata are pores in the leaf's epidermis, or outer surface. They are used to regulate the outflow of water vapour and oxygen from the plant leaves as well as the inflow of carbon dioxide into the leaves. Stomata are normally found on the underside of the leaves (protected from direct sun and exposure to wind).
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.
The underside of leaves is where the 'stomata' are to be found in most (not all) plants and it is through these stomata that the gas exchange occurs. The upper surfaces of leaves are usually tough and shiny to protect the leaf and shed water. If the stomata were on the upper surface and the leaf was wet, the water would block them and impede gas exchange.
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.
The stomata have to be able to access air easily as its purpose is to take in and give out carbon dioxide oxygen. Since both the water lily and lotus are water plants partially submerged in water, air would be more easily accesible from the upper surface.
In monocot leaves stomatal distribution is almost evenly on the upper and lower surface of the leaf. In herbacious dicot stomata is distributed more on the lower surface than the upper surface. Lastly in woody dicot there is not stomatal distribution on upper surface but great distribution on lower surface of leaves.
On a dorsi-ventral leaf most of the stomata are found on the lower side of the leaf, that remains away from sunlight. On an iso-bilateral leaf stomata are present on both the sides, upper as well as lower.
There are about 92 stomatas on upper surface and 39 stomatas on the lower surface. In a dorsiventral leaf number of stomata is more on the lower surface hence the above answer may please be verified
