The gauge system for Patagonia Lake is down due to either a dead battery or a damaged solar cell. But looking at our we**am there, water is trickling through the spillway. This makes it more likely that the crossing of Pendleton Drive at Sonoita Creek can close down due to heavy rains in the Rio Rico area along the Sonoita Creek Valley. Please pay attention to the signage on both Pendleton and Rio Rico drives for the closing of the crossing.
