Based on the insights provided by Randy Blaukat in the video, during March and April, the mid-lake section of Falls Lake would likely be the most productive area for bass fishing. This recommendation comes from the understanding that in many lakes, including Table Rock Lake which Randy mentions, the mid-lake area offers a balance of cleaner water, moderate temperatures, and suitable habitat transitions that bass prefer during the pre-spawn period.

In mid-March, you'd want to look for areas where the water clarity begins to change as you move up the lake. This is often where bass start to transition from their winter patterns to their pre-spawn behavior. The mid-lake region typically has the right mix of water clarity and temperature, which can make bass more active and willing to bite.

For Falls Lake, you might want to focus on secondary points within creeks, channel banks, and docks within a five-mile section of the mid-lake area. Also, pay attention to rock transitions along the main lake. These areas can provide structure and cover that attract pre-spawn bass.

Keep in mind that weather events, like torrential rains, can temporarily change conditions and affect where bass are holding. After such events, look for stained but not muddy water, as this can also be a hot spot for bass activity.

Remember, these are general guidelines based on patterns observed in similar lakes. For the most current and specific information about Falls Lake, it would be beneficial to check local fishing reports, talk with area anglers, or visit local tackle shops for the latest on-the-water conditions and bass activity.
