Thanks for the ideas. The spring actually comes out about 3 feet above pond level. SO right now we have the water running into a ribbed pipe and then dropping about 6 inches into a gutter where it then shoots out towards the middle of the pond. I think we will try the gravel idea.
About ten years ago the pond had nothing but 2-3 inch bluegills. We through a couple 12-15 inch bass in which helped helped control the food web. Being twelve I thought it would be great idea to throw other fish in from our creek not knowing the consequences. So of course the 2 species we put in were green sunfish and brown bullhead. Neither fish has taken over but we have been removing them when ever we do catch one.
Btw the way I am from just outside Gettysburg PA.
