Nolin River Lake today: level, trend, source and access
Level against full pool
On Nov 5, 2026 the surface sat at 510.6 ft, 4.4 ft below the full-pool mark of 515 ft.
Level against the seasonal target
U.S. Army Corps of Engineers, Louisville District runs Nolin River Lake on a seasonal pool (bottom of the flood-control pool), so the level it aims for changes through the year. For Nov 5, 2026 the seasonal pool is 503.6 ft, 11.4 ft under the 515 ft summer level, and the target is falling. The surface, at 510.6 ft, is 6.9 ft above that target and 4.4 ft below the full-pool mark of 515 ft. The water above the curve is flood storage, which the operator releases when the rivers downstream allow.
The Louisville District keeps Nolin at its 515 ft summer pool from mid-April to mid-September, then lowers the seasonal pool line about 23 ft, to 492 ft by December 1, so the lake can catch winter and spring floods on the Nolin and Green rivers.
Between two dates the target moves in a straight line, as the published curve does. Source: USACE CWMS Data API, office LRL, location level "Nolin.Elev.Inst.0.Bottom of Flood Control" (2026 breakpoints), read on Oct 26, 2026. The operator can deviate from its curve for floods, droughts or dam work.
Trend
Between Oct 7 and Nov 5 (29 days) the level fell 4.0 ft, about 1.0 ft a week. The high in that window was 514.6 ft on Oct 16 and the low was 510.6 ft on Nov 5. In the last 7 days it fell 3.5 ft. The last 24 hours moved it down 0.84 ft.
Data source
The elevation comes from USGS monitoring location 03310900 (lake surface elevation above NGVD 1929, parameter 62614), last reported Nov 5, 2026. Feet from full pool, the trend and the figures above are computed from that reading and the published full-pool elevation; none is typed by hand. USACE Louisville (Nolin Dam) runs the dam on the Nolin River.
Recreation status
Status: above seasonal target. At 4.4 ft below full pool, the shallowest ramps can be out of the water. Check the one you plan to use with USACE Louisville (Nolin Dam). Against the seasonal target the lake is 6.9 ft above the level USACE Louisville District plans for this date. If the 30-day pace of 1.0 ft a week down held, the surface would be near 506.7 ft in four weeks. Releases and rain change that quickly.
Check an elevation against full pool
For readers outside the U.S., the surface of Nolin River Lake is about 155.6 m above sea level, and full pool is about 157.0 m.
Check any elevation yourself. Type a level in feet above sea level (a ramp cutoff, a marina mark) to see how far it sits below full pool and in meters.
