The Naruto world doesn't have that. so we can assume they use jutsu to reach similar depths, but if Kabuto had jutsu that far exceeded real-life capacity, he would've dug up Jiraiya's body. Therefore, whatever diving jutsu may exist, those jutsu are similar in capacity to human diving equipment.

Hence:


 * the lake/sea (apparently the only difference is whether it's connected to the oceans) doesn't have to be as deep as people think.
 * The lake/sea doesn't have to be as big as people think.
 * significantly deeper lakes/seas than what i stated exists.
 * these lakes/seas are not on world maps.

Since Kabuto has showed no Shark summons, that argument is invalid. He also commented other ways to gain the DNA. Thirdly he was limited in time.
