On this water

No member has posted conditions here lately. The gauge says what the water is doing; an angler who was standing in it says what that felt like.

Post a report

Bureau of Reclamation station 365, Heron Reservoir and Dam. Reclamation publishes a day or two behind, so the date beside the reading is the date of record, not today. Readings describe the reservoir at the gauge; a shallow arm miles upstream will not match them.
