The Rosendale Theatre’s Science on Screen® Series presents ‘Windshipped’ and ‘One Dam at a Time’


Stone Ridge filmmaker Jon Bowermaster will screen two new environmental documentaries, “Windshipped” and “One Dam at a Time,” 7 p.m. Wednesday, March 29 at the Rosendale Theatre, 408 Main St., Rosendale. He will be joined by Dr. George Jackman, Riverkeeper’s Senior Habitat Restoration Manager and star of “One Dam at a Time.” Matt Kovner, Town of Olive Environmental Conservation Commission and Third Thursday Environmental Series organizer will moderate the after-film discussion. The event is presented through the Rosendale Theatre's Science on Screen® series.

“Windshipped” (2022) documents the rebirth of the Apollonia, a 64-foot steel bottom cargo ship built in the 1940’s, as a cargo sailing ship on the Hudson River. Using sustainable energy, wind and sun, the Apollonia transports goods from the mid-Hudson area through regional ports, including Kingston and Poughkeepsie, to New York City and returns with cargo from downstate.

Filmed locally, “One Dam at a Time” (2023) features Jackman and highlights the challenges and efforts to remove old, unused dams on creeks and streams running into the Hudson River. Removing these dams restores these waterways to the aquatic life that depend on them.

Following the movies, the audience will be able to ask questions of the panel about issues raised in these films, and query Bowermaster on his career as a filmmaker and storyteller.

Bowermaster has produced and directed more than 30 documentary films and written 11 books. He is a six-time grantee of the National Geographic Expeditions Council and one of the Society’s “Ocean Heroes.” Over the course of 10 years, he and his teams brought back stories from the Aleutian Islands to French Polynesia. Currently, his One Ocean Media Foundation/Oceans 8 Films focuses on short films about the environmental risks to, and hopes for, the Hudson River Valley.

After retiring from the New York City Police Department as a lieutenant, Jackman earned his PhD in ecology, evolution, and behavior from the CUNY Graduate Center in conjunction with SUNY. He currently works on dam removal in the Hudson Valley and teaches as an adjunct professor at Queens College. Jackman’s research focuses on migratory fish.
