Now, this board here.....Is it just like a water gate?
Space it up "a couple nickles"?
Adjust the water speed accordingly to keep the box behind it regulated?
Having some issues with the pic
Awesome, thanks.View attachment 1722805 Thats correct,At least thats how I designed the table.Ill see if I can find a better pix. of it

I was wondering if I would want it to be adjustable, or hard mounted
Do you change it often?
I suppose I imagined more of a hardmounted, set height for a desired water depth.In the beginning i changed the height often to get it correct,But i don't anymore. So you could probably skip that .Cause now the 'proper height' is known.FOR this particular table & pump combo
I suppose I imagined more of a hardmounted, set height for a desired water depth.
Then adjusting the pump flow for proper performance.
I reckon that makes some sense too. Decisions, decisions.....Seems to me that a bottom outlet for water flow is uncontrollable (unknown until you try it) unless the "gate" can be adjusted. I would eliminate the bottom gate idea and make a dam (shorter then the sides and back) where water is forced to flow over the top of the dam as the reservoir over fills. Water seeks it's own level so it will overflow evenly across the width of the dam and you can infinitely adjust just how much that flow is (the water depth on the table itself) by adjusting how fast the reservoir is filled. There should be little to no turbulence at the base of the dam and what little there may be will settle down in a very short distance as the water levels out across the bed. Kind of the KISS method IMO.
Good luck.
In the type of reservior/dam system you speak of....What dam height would you suggest?Both are equally easy to construct. The difference is that one is only going to flow a pre-set amount of water (maybe too little, maybe too much) depending on the dimensions of the opening once the reservoir level is set unless that opening is adjustable. The other has flow regulated by a valve, which you will have to use anyway, so volume of flow, depth across the table, is adjustable without experimenting with different sized openings. No matter what design you choose, make sure that you tightly classify the feed so that gold is king.
Good luck.
PS In either instance, introduce the water into the reservoir evenly across and under the water fill level to prevent bulging and/or bubbles.
The dam can be about 1/2" shorter than the height of the walls since the flow down the table during operation will always be less than that. Bevel the bottom so you can install the dam slightly slanted backwards so when you tilt the table the water will still flow down the dam rather than free falling. If you don't bevel then just make sure the high point is still at about 1/2" shorter than the sides when installed and fill the void at the base.
