Hansen Dam Bird Walk

Hansen Dam is a huge area with varied habitat, and like the Sepulveda Basin is part of the City of Los Angeles flood control infrastructure operated by the U.S. Army Corps of Engineers. Unlike the Sepulveda Basin, in the event of heavy and prolonged precipitation water may be retained behind Hansen Dam for prolonged periods. This means it is not possible to follow the same route for all outings. In general they cover between 1 and  3 miles, and will be geared to the abilities of participants.

Reportedly over 280 species of birds have been seen at Hansen Dam, which holds the record for most species seen in a day in the San Fernando Valley at 120. The area we traverse is largely riparian adjacent to the lake and swamp, but also includes grassy lawns dotted with trees, Tujunga Creek, and the large rock rip-rap areas extending out from the dam (Rock Wrens!). Typically we see 30-50 species there on an outing, and it can be interesting. For example diving ducks in a parking lot submerged under 3’ of water!

Outings are on the fourth Saturday of every month at 8 AM. Please meet at the Ranger Station.  Walks will be canceled in the event of rain. If you’re unsure whether a walk is taking place, please contact your walk leader at batesbird@gmail.com or call 747-237-3720.
