• Where to Fish on Number 123 Reservoir

  Depth is not on record here, so the bank has to tell you. Levels move with the draw rather than the rain on water like this. Held water runs deepest at the wall and shallows back to the inflow. Reported across Saint Charles County: common carp, bluegill, green sunfish, channel catfish and orangethroat darter. County data is a starting point rather than a guarantee. Treat this water as a water to read rather than to cover.

• Seasonal Patterns

  Typical July readings run about 77°F; by January the average is down near 28°F. Most months fish reasonably, given the right weather. Cover comes and goes, so treat it with suspicion rather than trust. June to September is hot work, so the first and last hours are what count. This water runs to its own calendar within the local pattern.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Public data shows nothing built here, so treat the whole approach as informal. For the catfish, fish bottom baits into the deeper holes and let them sit. Check whether a boat is allowed before you tow one. Signs go up and come down, so check on the day. Failing this one, try Howard F Brewer Lake, 0.4 miles away. None of that is settled for this water in what we hold.
