Good or bad for the pond I would burn it. It's easier to move some ash if it is determined to be detrimental to the pond.
When you burn plant matter the nitrogen stored in the plant is released quickly back into the soil. This is the reason prairie grass is burned. To release the nitrogen to promote faster grass growth. Fast cheap fertilizer.
When plants decay naturally the release is gradual.
Much wood ash contains calcium carbonate as its major component, representing 25or even 45 percent. Less than 10 percent is potash, and less than 1 percent phosphate; there are trace elements of iron, manganese, zinc, copper and some heavy metals.However, these numbers vary, as combustion temperature is an important variable in determining wood ash composition. All of these are, primarily, in the form of oxides.
For a long time, wood ash has been used in agricultural soil applications, as it recycles nutrients back to the land. Wood ash has some value as a fertilizer, but does not contain nitrogen. Because of the presence of calcium carbonate, it acts as a liming agent and will deacidify the soil by increasing its pH.

Not to be argumentative, but it seems to me that this does not apply to the OP's situation. If he burns the brush pile, he is going to end up with ashes that then may wash into the pond. It seems to me that the critical question is the chemistry of the wood ashes.

As of now, moving it is not an option. I have a tractor with FEL, but no grapple. The ditch is about 40 feet long, six feet wide and about 2-5 feet deep. It's a major eye sore and I've been trying to clean up this property. It may have wait until I get a grapple.
