Add real flood gates
In real life the way a floodgate works is by letting water at a lower portion of the dam in order to store water up steam. In game "flood gates" open from the top and don't allow for this functionality. Its almost like the game is specifically designed to make functional dams impossible. As floodgates don't work as they should and you cant build a levee on a dam/platform.

KrufarI think the issue you are having here, is similar to something I noticed. We're limited by a max lvl 3 flood gate. Should be a steel one that's 4 and 5 high to stay in sync with max height pathing supports. :)
But a dam can be build on if I remember correctly, it just can't be adjusted. Then you could have 1 dam at every level, which will auto control. Hmm, havent tried this yet, gonna implement that next time I play. -

Gin FuyouIt doesn't matter where water comes out, you are missing some basics. Floodgate a real and the work for what you said.

Water did not behave like that -

Trajan MergedAdd a conduit so you can release water from the bottom of the dam instead of the top

Vicky LangstrumpfI think bigger locks would be great. Currently only three blocks is a huge limitation. Likewise deeper pumps.

David C Bollingeractually, water can behave like that, letting it out the bottom would provide resistance to flow, without stopping the flow entirely. This would cause some of the water to back up, gradually increasing the pressure and thus flow through the hole, until either an equilibrium was reached at a higher water level, or the water flooded over the top of the dam.

Also, yes please on the metal floodgates. And if you do have floodgates that open from the bottom, make them separate to the current ones, because both are useful.
and more granularity to floodgate heights. changing it by .5 at a time just isn't cutting it for me. I want to be able to gradually let the water out during droughts. -

Thefirewarde MergedMany dams discharge a metered rate out the bottom of the dam rather than or in addition to a floodgate or spillway. This block would allow a limited amount of water to flow through a dam at the base. The maximum output would be equal to the output of one wier block with a full river behind it, and it could be closed like floodgates are closed - adjacent blocks working together or separately via toggle, and with the only two states being open or closed.

This would permit steady state flow down a canal or a raceway, without having to constantly monitor floodgates. -

userr1453 MergedIt would be good to allow dams to empty via the bottom using a "floodgate block", think the triple valve block but allows the dam to empty from the bottom, until the downstream level has reached a set point set in the "floodgate block".
In case it is of interest I work in the hydro power section -

Seriously UnseriousDraining water from the bottom is used, sometimes as an emergency outlet, sometimes as the normal outlet. There is a risk with these discharges that if the pressure builds up enough, they can form a syphon effect, which would suck anything too close to the intake through. If the water level behind a low outlet dam gets high enough, we could have the outlet form a syphon effect, where it starts discharging much more then it's normal amount of water and any beavers swimming too close, say within 1 or 2 tiles of the intake, risk being sucked in and drowning. This means you'd have to carefully consider where you place them in relation to any water paths, and how you manage excess water and emergency drainage. Flood gates can be done to drain from the top, especially if it's for an emergency spillway to prevent flooding or water topping a dam, which can trigger catastrophic failure of the dam IRL.

Stephen MergedFloodgates should be able to open at the bottom rather than just the top. Like real dams, they don't need to be completely full to release water.
I would want to be able to build a big dam and have a constant rate of release downstream and not have to adjust floodgate heights constantly during the dry season as the level decreases. -

QuantumI agree I would love to see flood gates.
I have a solution for anyone currently playing that wants "flood gate" functionality but. I'm fairly sure this is a bug and will probable get patched eventually (hopefully patched when they add flood gates)
https://i.imgur.com/cjtvwje.png
in this picture the lowest spot water can escape is at the same level as the lowest spot the water will flow to thus the water acts like a river "normal" all the water in the tank rushes out the 7 high tank
https://i.imgur.com/LhctEJA.png
if you add a single block at the bottom. OR if you tnt the terrain imminently in front of this outlet. the lowest level of the water now flows down when it comes out. this for some reason changes how the flow behaves. instead of having "7 blocks" of potential output it actually caps at 1 block of potential output
https://i.imgur.com/WxAHYL3.png
and no, this is not just water input reaching equilibrium with output, I made a giant tank to test my theory. -

Konstantinov RomanYou might not even need to add new "real" flood gates. Just allow building levees on dams. We can already "meter" the flow by opening and closing floodgates, we just need to be able to have an opening at the lowest level of the dam.

Gin Fuyou AdminRoman, that's not possible with current code technically.

Vogelseuche MergedHow about the possibility to open the flood gate not only from the top (water heigher than this will overflow), but also the possibility to open the floodgate from below:
Then a constant (or almost constant) flow of water out of the damn is possible, if enough water is in the damn.
-> You can build a buffer damn that is constantly filled with water
-> You can keep the river below the damn always wet and the land furtile
-> You can produce constant energy with water wheels
-> You don't have to adjust the height of the floodgate constantly
You can use wind energy for the pump (this energy is not always available) and buffer it to create constant water wheel produced energy.

Nilswhen the water level rises the pressure and thus the speed of water through those gates could increase. Creating the incentive to manage water to optimize water wheel performance.
maybe a turbine for late game? -

GeofferyI like this idea for automating my reservoirs. If the water left through the bottom, one could keep a constant flow until the reservoir dries.
This could be implemented as a toggle on the current floodgate; or a separate building.
Separate spillways, or other mechanism would be required to manage overflow; but that's unrelated to this suggestion. -

TajrYeah i dont think the top or bottom thing matters but a 5 high metal floodgate would be a great addition. especially with the limitations of the districts
-

FluffiestI like this idea, but also it should definitely require steel to handle the increased pressures vs. a top-opening floodgate.

TKWhile all of these suggestions are cool, I would like to point out that the developers have somewhat commented on this issue before: With the way the game's water engine works, water cannot pass underneath other water. By having floodgates open from the bottom, it would create issues where if water is flowing over the top of the dam and the gate is opened, water would pass over itself and break the physics engine. This is, unfortunately, a large limitation of the game's water physics, making dams and levees on platforms impossible, along with many of the suggestions here. Sorry.

ZefnolyWhile the engine cant let water flow underneath things, there are games with similar waterphysics that has. Cities Skylines 1 has nearly identical water physics and they made it work. What their dam does rather than letting water "flow under dam block" is that a drain will delete/drain water in front of dam. And on the lower end of dam the exact same amount of water is creates. This flow can technically speaking be controlled for a specific flow to immate water flowing through the dam at desired amount.
The components code wise should already be in game.
Basically a modified variant of the mechanical waterpump should be re-programmable to do what we want here.
Modify it to be 3 blocks long and 1 block tall. Remove mechanical input. And if will "pump" water from one end to the other as long there is more water on one side. And then make the height difference decide the flow. The part of it in the middle would behave like a leeve. -

sajagiI am not sure whether this was already mentioned, but a way to go (while also considering the engine limits) would be an auto-adjustable floodgate, that would allow some minimal (adjustable?) current on top. It wouldn't even have to be extra precise, e.g. changing its height every x seconds (game-time) only, based on the current water flow. Some hysteresis or height speed limit will probably be required to avoid feedback loop.

Oscar MergedMaking huge reservoirs is fun, but if they are more than 3 tiles deep its difficult to release water downstream when you need it. If there was a way to release water from the bottom of a dam you could use a single deep reservoir to keep water pumps going and irrigate crops downstream during a drought instead of making a deep one for your pumps and a much wider and shallower reservoir for irrigation. Since real dams can have water released from the bottom I think this would make sense in game.
Maybe the water would leave the bottom of the dam with much more force than the top, and so require different engineering by the player to avoid flooding. I don't know how the water physics would react to something like that. -
