** As of 6/27/2025, the flag pole is broken so law enforcement may be practicing at anytime. Just be aware.
Vehicles are prohibited from driving along the levee of the deep pond north of the office.
Visitors must keep vehicles on the paved portion of the road, so as to avoid driving over sprinkler heads.
Birders need to vacate the facility prior to 3 PM.
Lastly, remember to sign out as you leave.
This facility is open from Monday through Thursdays only. It is possible, however, to bird a few of the ponds with a spotting scope after hours or during the weekend, either from the Morgan Street side or along the eastern boundary on Blaker Road. It is not permitted to park along the south end canal road by the orchard.
