This type of deep steep sided pond will still accumulate a "normal" amount of organic matter because a lot of the organic matter is derived from dead plankton. In many instances this accumulation is very close to 1" per year. Dead plankton is primarily phytoplankton and zooplankton. "Normal" used here is a very relative term. Ponds that receive lots of tree leaf or terrestrial organics are not IMO normal ponds. Dead organic plankton matter is very dependent on the productivity of the pond - often determined by water transparency.
