About Lake Moultrie
Lake Moultrie is a reservoir on the Cooper River in South Carolina, operated by Santee Cooper. Its full summer pool sits at 75.5 ft above sea level. Live water levels come from USGS gauge 02172000 and update every 15 to 60 minutes.
Understanding Lake Moultrie's water level
"Full pool" is the elevation Santee Cooper targets when Lake Moultrie is completely filled — 75.5 feet above sea level. Above that line the Corps deliberately keeps empty "flood storage" to absorb heavy rain, so the lake rarely sits far above 75.5 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
In a normal year Lake Moultrie sits highest through the summer recreation season and lower over winter, when the Corps makes room for storms. Extended dry spells in late summer and fall are what usually pull the lake noticeably below full pool.
The all-time high and low above come from the full USGS period of record for this gauge — often decades of data — so they're a good yardstick for how unusual today's level really is. Use the chart's "Compare 5 years" view to see whether the current reading is running ahead of or behind a typical year.
