Help Developing Seepage Spring in Nearly Flat Muddy Area

I'm going to start of by saying that I am new to this site and very much enjoy it, having already found both interesting and helpful information.  However, I have been scouring the web for about a week but have been unsuccessful in finding answers to my questions I have for my particular spring "seep".

I purchased a couple of acres in South Mississippi less than two miles from the Gulf of Mexico.  

The property is nearly six feet lower in elevation than the adjacent property just toward the North.  There is a small creek running across the front of the property (close to the road) and then along the side property line, which flows constantly year round (sometimes only a trickle) so I knew beforehand that I would be facing a challenge dealing with some wet ground.  With access to heavy equipment, I installed end-to-end 42"x29" Arch concrete pipe for driveway culvert, close to 300' limestone driveway, and I have hauled in roughly 800yds of sandy material to build it up where I would like it (still not quite satisfied).  However, I am still faced with a least (2) springs that I have learned are "seeps" which I would estimate flow at 1-2GPM each.

The difference between all the information and videos I have studied online and my situation is that my ground is not hillside or located in rocky terrain but instead under a leaf covered surface of mud with sandier material as I dig.  

I could continue to haul in more material and build up the site to the point where I could divert all water along the perimeter of the property and to the creek but I would like to utilize this free water for watering the lawn and possibly supply water to chickens.

Now my question: Can I dig a collection pit where these seeps come together and they form a slow stream above ground? And from this point, can I install the filtration gravel, piped to a spring box?  Or is it necessary to dig until I find the source of each seep (which seems impossible)?  Any suggestions would be extremely appreciated.

Zach weiss with elemental ecosystems did an assessment on my land. I walked away with a better understanding of how the underground flow works.

We spent the day drilling core holes up to 8ft deep. Equipment was simple. A skidsteer with an auger plus a 4ft extension on the auger. I own the equipment, but the going rate(my area) for a skidsteer/operator is $100 in transport and $10 hole.  Thats for a fence. I'm sure there would be a premium for the random holes throughout a property. Maybe look for a half day rate.

What he was looking for was underground water. After that he looked for the "bottom" of the underground flow. In one hole at 4ft we had water. Another one had water at 8ft. We probable drilled 8 holes total.  8 ft was our limit. Had we gone deeper we may have found it everywhere. The fascinating part was after we found the wet sloppy layer, not to far under that we found dry clay. Amazing stuff. While this was being done for water retention planning (a series of ponds with sealed dams but not sealed bottoms)  my mind kept thinking about shallow hand pump wells or solar submersible pump. I've got this hole with water. Its sized to drop in a 4" casing and a handpump with 1" line. That may not sound exciting, but my house well is 300ft deep. Central texas. Limestone. Yuccas, cedars. Not known for "water".

We found water, we knew how high and how deep it went. The hardest part for having a shallow well was done. But it wasnt hard. Fascinating to me.
