When we first bought this property 27 years ago, we planned a pond that was going to be spring fed and about 140 x 70 and about 15 feet deep at the deepest spot. There is a ravine that runs through the middle of our property that has a very small stream running through it that flows about 10 months per year and originates from a spring on our neighbor's property.
When we first moved here, most of the property was wooded. The woods extended from the edge of our backyard all the way to the back of our property some 750-800 feet back. We cleared the trees all the way down to the ravine (about 250 feet) and somewhat beyond it and the width of our property (about 150 feet) in preparation (of course, we wanted to be able to see the pond from our house).
First, we had to get permission to build a dam. I designed an earthen dam that was approved. After that, we had to have a site survey. The site survey determined that there was a 25-30 foot area of wetland on either side of the 1-2 foot wide stream that ran through the middle of the ravine. We had to come up with a plan to relocate this wetland. Once again, I did some research and came up with a design that incorporated and extended shallow side to the pond that would support the relocated wetland. It was approved.
We thought we were in the clear when out of the blue we got about a 2-inch-thick packet from the State with pages of regulations and "studies" we had to have performed before final approval, including studies like endangered species study, historic buildings study (in case we wanted to flood historic buildings!), storm studies, run-off studies, and on and on.
After adding on the cost of the studies to the already high cost of building a dam and relocating the wetland, we decided to abandon the project.
Here are two pics of our "extended backyard" after we cleared all the trees to a point beyond the ravine. You can't actually see the ravine in these pics, but it is set in the area about halfway where the land begins to rise up. (Sorry for the small pics)

And this pic taken in May 2020. We have let everything grow back from the ravine on back.
