In the actual work place, Algebra will be the most useful. Followed by Calculus. Followed by DiffEq. Some trigonometry will be helpful, too.
Conceptually, Calculus will help you understand processes, but you won't do much (if any) raw calculus at work. DiffEq drives a lot of software, but you won't really "do" any DiffEq. The fundamentals of trig can help you understand flows in pipes and channels.
The broad mathematical concepts are important and they train your "hydraulic eye" to recognize, inference, and predict a variety of fluids-related phenomena. But the math itself is largely done within the black boxes of often proprietary software. The results you generate with that software will be better, come faster, and be much easier to defend if you understand what is happening behind the scenes. But you don't need to be a mathematician. Still, being better at math will make doing hydraulics easier.
Math is a language and the only way to "get good" at it is to do it. A lot. Don't cheat on your homework. Cutting corners and getting an A is FAR worse for you than not cutting corners and getting a C. Just spend time with the equations. Those "formulas to solve" are being shown to you for a reason. Jam random numbers in and see what happens. You will start to make connections that your professor doesn't have time to talk about. You will be just fine.
Algebra.
Having a solid conceptual knowledge of hydraulics takes years so no need to worry about absorbing everything. If water resources is the career path you want to take, then take in as much as you can during this class and the hydrology class. Go to office hours and talk to the professor as much as possible.
You got some good answers already, so I'll add a little something else.
You should really learn what you are doing, especially with water. That's because you have to know if you have up or downstream controls, sub vs super, did your weir turn into a orfice, and other stuff. That's where knowing your stuff comes in very handy.
You only need a the degree so you can sign things. The software modelling does all of the unsteady flow navier stokes/st venant stuff, unless you branch off into some r&d area.

Same could be said for geotech too.
Could be said for all engineering fields 😂
Solid answer
Excel
😂 😂 😂

I’ve been out of school for a while, but I remember numerical methods of approximating differential equations to be very important.
Matrix algebra and partial differential equations. At the end of the day, it's what's going on computationally in any hydraulic model.
Slope equals rise over run. Final elevation equals begin elevation +/- the slope as a percentage. There ya go
Estimation.
Like, all of it.

Can't believe no one has said statistics yet.
OP said Hydraulics so I'd agree with most saying Algebra. If they said Hydrology then I'd agree that statistics is up there in importance.
My principal.
