When does Logan Martin Dam usually run?
Over the last 7 days the powerhouse was turning in 70 of 167 hourly readings, peaking at 10,519 cfs. It ran most often 6 AM–8 AM, 3 PM–10 PM Central (on at least 4 of 7 days).
- ● Powerhouse generating (cfs)
- Empty gap = ○ not generating
That’s last week’s pattern, not a promise. Alabama Power posts tentative generation schedules on its lake pages at apcshorelines.com, and those can change with rain and power demand.
Last 30 days: this year vs. last year
Over the last 30 days the pool ranged from 462.97 to 464.26 ft.

Reading the water on Logan Martin Lake
If you fish below Logan Martin Dam or up the Coosa River arms, the powerhousenumber is the one to watch. Moving water pulls bait and sets fish up on current breaks; slack water can make a tailrace go quiet. The pool level tells you the rest — how much water is over the shallow cover, and whether that ramp you like still has enough at the end of it.
Alabama Power runs its storage lakes on an operating guide: the highest level it may hold the lake at under normal conditions. Per Alabama Power, the guide starts the year at winter pool, rises through late winter into spring to summer pool, holds through summer, and drops in fall and early winter to make room for winter and spring flood flows (source).
Logan Martin’s normal winter pool was raised two feet, from 460 to 462, starting in the fall of 2022. (source)

Data source
Pool, guide-curve, powerhouse, spillway, release and tailwater numbers come straight from the U.S. Army Corps of Engineers Mobile District CWMS feed, where Alabama Power reports hourly readings.This page re-checks the feed every 15 minutes; readings usually land an hour or two after they are taken. A reading older than 3 hours is marked stale. Elevations are feet above mean sea level; flows are cubic feet per second (cfs). Page checked Nov 13, 6:45 PM CST.
