Autumn Creek Maintenance

We have a tiny spring-fed creek which runs year round through our forest. We keep the forest as wild as possible, but do splash in the creek on hot days. It has a large amount of organic debris in some areas and clear gravel/rock in other areas. Now it's filling with falling leaves and I'm wondering if it's good creek maintenance to remove autumn leaves from the water or is it better to let them continue to accumulate?

Its my guess normally you have heavy rain at sometime and it flushes out the leaf load.
From a practical point of view it will do no harm to keep a small pond clear of them.
Creeks are hard to play with because just about anything you do, other than remove a pile of leaves, will alter things.
If you built up a wall to make the pond deeper, erosion may occur on the side or the pond will silt up.

Thank you for your input. I was wondering as some pockets of leaves don't seem to move even after a few heavy rains. I was unclear if picking them up would lead to erosion or if leaving them contribute to a mosquito problem. It's good to learn more about being a good steward of our waterways :)
