watershed 1
The Peralta Creek Watershed, also known as East Creek Watershed, stretches from the Oakland hills through urban residential and commercial areas to the San Leandro Bay. The creek gets its name from the original Peralta family hacienda, in today's Peralta Hacienda Historical Park. The watershed is drained by several small creeks that join near the bay. From north to south these are Peralta Creek (the largest), Courtland Creek, 54th Avenue Creek, and Seminary Creek. Before flowing beneath I-880, the four join to form East Creek Slough, a straight engineered channel that replaces an old meandering tidal-marsh slough of the same name. East Creek flows into the San Leandro Bay near 50th Avenue. The lower part of Seminary Creek is also an engineered channel; the upper part originally joined Lion Creek.
Note: Not to be confused with Lion Creek, which was originally called East Creek, but drains into Damon Slough.
