Description: The permanently flooded wetlands in this alliance occur in north-central and southeastern Colorado in two very different habitats. These wetlands are dominated by hydromorphically rooted herbaceous species. One habitat dominated by ~Stuckenia filiformis (= Potamogeton filiformis)$ occurs in shallow, montane lakes in north-central Colorado, elevation is 2060-2530 m. The climate is cool, with a relatively short growing season. The mean annual precipitation is 20-40 cm, mostly falling as snow. These lakes get water primarily from snowmelt-fed streams. The other habitat dominated by ~Potamogeton diversifolius$ is found in the canyons of southeastern Colorado, growing in plunge pools in sandstone bedrock. The elevation is usually between 1100-1850 m. Climate is semi-arid with hot summers and cold winters. The mean annual precipitation is 25-35 cm, mostly falling during the growing season. These pools fill up with runoff during summer thunderstorms. Both are permanently flooded; however, the water level in the plunge pools can vary greatly during the year. The herbaceous layer in the montane wetlands is dominated by the submerged plant ~Stuckenia filiformis$, which often grows in dense mats. Associated immersed plants include ~Sagittaria cuneata$ and ~Polygonum amphibium var. emersum (= Persicaria amphibia var. emersa)$. This wetland is found in open water surrounded by ~Carex$ and ~Scirpus$ marshes growing out from the shore. The bedrock plunge pool wetlands have been described from canyons where pools form in the sandstone bedrock. They are dominated by ~Potamogeton diversifolius$, another hydromorphically rooted, submerged forb. Little is known about these wetlands.
