My ocean is flowing upstream and nothing I do can fix it.

[Loopy Legend]

So as the title says I can't get my ocean to stop flowing halfway up my river system. This is despite the fact my only water sources are at the ends of my rivers and terrain elevation is heading on a downward elevation the closer to the ocean you get. I've been pulling my hair out for days trying everything I can think off, watching YouTube videos and nothing seems to stick.

Tried changing sea level lower?

Can you screenshot it? If it is water pumps, then it is because your water pumps seem to be drawing in more water than the river supplies. Else the grade is too shallow because water does "evaporate". If your river is artistic with almost no grade, then your source might not have the output to match the later downstream evaporation, resulting in the ocean filling it.

If you have the DLC that allows water outlets (I think disasters) then what you can do is use water towers connected to an outlet in order to generate an artificial river supply.

I'm in the map editor, pumps got nothing to do with it, Sorry should of mentioned that sorry.

Ground level at the bottom of the river does not matter for the visible waterflow on the top of the water as long as the ground level is below your water source level and your sea level.
If ground level starts to matter you will see little steps in the river, like small waterfalls.

If you don't see those steps/waterfalls it isn't about ground level but about surface level which is determined by water source and ocean level.

Somehow your water source is unable to fil that area so the ocean will fill it up to sea level
Water sources are limited by their capacity, ocean level gets water from all ocean edges. With a sizeable ocean which touches a substancial ammout off map edge this means the ocean acts as practically unlimited capacity water source.

You can try to lower the sea level so the ocean doesn't spill so far inland.

As mentioned above: If the river is long enough evaporation will come into play, your river evaporates and water gets filled in from both ends.
Check your water source is it at max capacity? Eighter turn up it's capacity or double it up with a second watersource next to it.

if that is still not enough you will need to place water sources along the river to replace evaporation.
It will be hard to keep a uniform downstream waterflow when placing additional water sources in the river... it can be done with some finely tuned water source height and capacity settings, or you can create lakes along the river and place the water sources in the lakes... the lakes will "explain" the missing waterflow in a visually pleasing way... or you create tributaries, little rivers joining the big one, that way the water source is at the start of the little river and only indirectly adds water ot the big river.

It also isnt necessarily a good idea for long and consistent run rivers, at least in a manner so has a usable flow. The evaporation and other math voodoo in the mechanics can result in rogue wave formation. Tucking buffer pools into rivers are a good mitigation.

another thing that can help, move the water sources back in the ocean. If I understand your explanation right you said you had some at the exits of your river. You want them farther back than that.

Nope just at the end of the rivers. Placing any midway in the rivers or near sea entrance only makes back flow.
