Looking for input on water drainoff usage

I  have recently re-graded my side yard and put gutters on my house  and am looking for water use ideas.


I have 300 gallons of catchment on one side.  on this side i have a hill catching water runoff and gutters piped and draining off the roof water on that side and emptying out onto a small slope past the house...


Soooo  i aplan on putting a little rock area in at the water exit to avoid erosion there  but i want to plant some thing s that will thrive with the wetter conditions.    I have 2 option with th water one is to stop the pressure and just let it dispers and eventually build some berms down the slope as it continues down another 30 ft so that could work well i think but wont happen for a little.

the second idea I am unsure about is digging out maybe a 5x5 area where the water exit and dig it down a few inches ad some rock maybe,  to somewhat capture a little water and then have an easy overflow area to flow ut as mentioned above....  Good idea?  what to plant there?

I am looking for ideas for around the outlet to


so genearally good permaculture plants for wet/ possibly some standing water?

2 issues is that  the house is 10 ft away  so so big trees or massive root systems,  and there is a black walnut with roots in the area

I am leaning towards the first idea but the 2nd pop in so i thought i'd ask

A couple good plants for standing water:

Cattail (edible and useful)
Canna (edible and pretty)

wow canna is beautiful.  I will have to look it up.  Thank you

Most mints like wet feet.

Thanks John,    that was one i was thinking off.    Figured once it takes well it will fill in around rocks etc nicely too.

Wapato (Saggitaria latifolia) - Chinese Spinich (Houttuynia cordata) - Water Cress
A lot depends on how long your rainy season is and whether you'll dry down in summer -- in which case many of these plants are not viable... Blueberries are good for seasonal saturation.

not  an extremely long rain season    but not dry either......i like the blueberries  idea

Both Cattail and Canna can endure periods of dryness though they will go dormant (go brown and look dead).

Where do you live? Depending on location water catchment may in fact be illegal with out a permit.

Thanks Emerson
No  def. not illegal...we barely have enforced building codes here......plus my yard has been catching the water for 80 years...i just moved it up 75 ft..........but seriously no thats not an issue for me...I am western N.C.  mountains  though......

I always find it hilarious that some people in an office feel they have a right to tell you what to do with water falling on your house
