31. Evidently three distinct stages of geochemical and trophic development are represented, the sequence of stages being tentatively generalized as follows for reservoirs of this region: (1) soon after impoundment, rapid leaching of nutrients from submerged land causes a brief rise in productivity and aberrantly high levels of dissolved low molecular weight phosphorus and nitrogen in the backwaters; (2) subsequently, a "pulse" of soil humic matter released more gradually into the backwaters depresses productivity by fixation of minor elements such as iron, even if the dissolved phosphorus levels are high; (3) finally, a steady state is restored when this anomalous accumulation of humic matter is removed from the water column by sedimentation or flushing, allowing productivity to return to higher levels.
