Description: This alliance is found in ponds in the midwestern and western United States. Stands are found in glacial ponds, or prairie potholes, in the northern Great Plains and in ponds and slow-moving water in Colorado. Stands are located in shallow (20 cm) to moderately deep (1 m) seasonal or permanent standing water, but with standing water present throughout the growing season. The ponds characteristically have brackish water (a relatively high ionic concentration) and bottoms composed of mud, mud mixed with gravel, and occasionally, organic matter. Parent material is often glacial till. The elevation of the plant associations ranges from 150-600 m in the Great Plains to 1200-2950 m in Montana and Colorado. Submerged and floating aquatic vegetation covers at least 25% of the surface. A moderate to dense cover of submerged aquatic macrophytes characterizes this alliance. The submersed leaves are filiform in shape and not conspicuous beneath the surface of the water. ~Stuckenia pectinata (= Potamogeton pectinatus)$ is the dominant species, and ~Potamogeton pusillus, Zannichellia palustris, Myriophyllum spicatum, Ruppia maritima, Sparganium angustifolium$, and ~Ceratophyllum demersum$ are associated species. The macroalgae ~Chara$ sp. is usually present. Adjacent vegetation is midgrass and tallgrass prairie on the plains, and ~Carex aquatilis$ and ~Carex utriculata$ wetlands in Colorado.
