With the rain we've been having, Arroyo Valle or Arroyo Del Velle was running high through Sycamore Grove Park this weekend.
Did you know the arroyo is a 36 mile-long westward flowing stream that begins in northeastern Santa Clara county and flows into Alameda county where it's dammed to form Lake Del Valle?
After the dam, Arroyo Valle is a tributary to Arroyo de la Laguna, which in turn flows into Alameda Creek and from there to the San Francisco Bay.
