Potamogeton ogdennii, or Ogden’s pondweed, is an aquatic annual plant. Its leaves are 2-3 inches long and very skinny (less than 1/10th of an inch wide). The flowers are held on stalks above the surface of the water, but fruits are uncommon. Vegetative budding during the winter is probably its most common method of reproduction.
Potamogeton ogdennii is primarily threatened by aquatic invasive species and the herbicides that are used to control them. As well as by human actives that disturb its habitat.

Potamogeton ogdennii grows completely submerged in alkaline lakes, beaver ponds or slow-moving streams.
