I am new to pond building. I have bought "Perfect Pond - Want One?" by Mr. Lusk and Mr. Otto. I have found it very informative and highly recommend it. It appears that they are my neighbors just across the river. My first question as I start compiling information about my site is - Will the natural spring that will be partially submerged at the shallow end of my pond cease to flow if it is under water or will it force water back up to the source of the spring or will it be of no concern??? About a year ago for fun I used my small tractor to build a dam below where my permanent dam will be and within two days the spring filled a 4 foot deep area. This area also will have 30 acres of terraced runoff water. Water supply is not an issue. Any thoughts or ideas are appreciated as I proceed with this project? Picture to follow I love this forum, best thing that could have happened to me!
