Lake Mead stripers transition as fall cooling takes hold
Late September marks the seasonal turn on Lake Mead and the lower Colorado River. Surface heat is easing off summer highs, and striped bass are shifting into their fall feeding pattern, moving off deep summer haunts and regrouping around main-lake points and channel edges as shad begin schooling tighter.

Expect the cooling trend to continue over the next few days, pushing striper activity increasingly toward dawn and dusk windows as light penetration and comfort favor low-light feeding. The waning gibbous moon this week should keep night and early-morning bites active, particularly where shad concentrate along drop-offs and submerged channel structure.
Over the coming weekend, main-lake points, humps, and the transition zones near the river channel are worth prioritizing as stripers stage ahead of the fuller fall shad run that typically builds through October.
Context
This timing is on schedule for Lake Mead's fall striper cycle. Late September into October is when the reservoir's stripers historically begin keying on shad pushed by cooling water, a pattern that builds through October and typically peaks once overnight temperatures drive a more pronounced shad die-off, drawing surface feeds within casting range of points and rocky banks. Typical for this stretch of the calendar, the bite should keep strengthening rather than declining from here.
