📊 Fishing Conditions

The fishing conditions score rates how favorable Simpson Lake looks for the day you pick (today by default), from 0 to 100. It adds up five things: how recently the lake was stocked, the moon phase, the season, how many game and panfish species live here (such as bluegill, brook trout and brown trout), and the size of the lake. It does not include the weather forecast. The cards below show how many points each factor contributed.

Fishing Tips for Simpson Lake Today

Fall fish at Simpson Lake are feeding heavily before winter. Match the forage: shad, crawfish, and perch patterns work well.

📊 Fishing Pressure

Fishing pressure is our estimate of how busy Simpson Lake is likely to be today. It looks at the day of the week, the time of year, and whether the lake has been stocked recently, because fresh stockings tend to draw anglers. Lower pressure usually means more room to work the water for bluegill, brook trout and brown trout.
