Hi and welcome Kerrminator. This is the place to improve on your original ideas and get some excellent information and feedback. I have a few questions for you. 1st. is this just a wet weather spring or does it flow year round and 2nd, where are you located. Last year my neighbor and I increased the size of the pond on our property border line for wildlife's benifet. It is fed from a wet weather spring, usually only in the spring of the year. Next I lined a "chase" with rock to direct rain water to the pond. Some grass seed helped to act as a filter to keep incoming water somewhat cleaner for the deer. My/our problem is now the spring has been dry for months and only rain water enters the pond, with no new water the water gets awful looking. We have talked about some plants to help but haven't acted on anything to date. Good luck and again welcome, Eric.
