Congratulations! I wouldn't be discouraged at all. The reality is, most ponds are filled via runoff but yours has an advantage, you control the point of entry for most of the water in your pond.
In the future, with a little ingenuity, you can monitor and filter all the water that enters your ecosystem. In the meantime I would buy one of those inexpensive solar fountains with led lights and a few pounds of fatheads to eat the mosquito larvae.
Consider yourself lucky.
Thank you. That is encouraging. When I get back out there I'll be sure to get some pictures of the inlet pipe and concrete splash thing. Maybe some nice folks here will have an idea for filtering.
There's electric that runs out to the dock, and it looks like the red buoy is attached to a bubbler.
