Frequently Asked Questions a. Why are so many rivers and sloughs closed? i. The releases of water up river, combined with heavy rains have caused the rivers and sloughs in the south Delta to reach extremely high levels on surrounding levees. Wakes from boats at high tides, could pose a risk to levee stability in some areas. b. How long will the closures be in place? i. The closures are dependent on water levels in the Delta systems which fluctuate with rain events and possibly again in spring or early summer as the snow melts in the surrounding mountains. Closures are lifted or modified by the San Joaquin County, Office of Emergency Services. c. What happens if I boat on a closed river or slough? i. County Sheriff Marine Patrol divisions and the United Sates Coast Guard will be enforcing the closures. d. Where is recreational boating allowed while the closures are in effect? i. During the appropriate times outlined in this directive, you can pleasure boat on Old River, Mildred Island, San Joaquin River, or any River or Slough not closed by the San Joaquin County Office of Emergency Services (see attached highlighted map). e. Will bridge operators open bridges on closed rivers and sloughs? i. Only for emergency boat traffic while the closures are in place (Orwood Railroad Bridge, Bacon Island Bridge, and MacDonald River Bridge will open per their normal schedules and all other bridges not in a closed area). f. How do I find out about bridge schedules and when high tide is on any given day? i. You can find bridge and tide information at, DeltaBoating.com ii. http://deltaboating.com/tides/orwood.php g.
