About this reservoir

Martins Fork Lk At Martins Fk Dam Nr Smith

Martins Fork Lake is a reservoir located in the Harlan County of Kentucky. The lake was created in 1979 by the US Army Corps of Engineers to control floodwaters on the Cumberland River. The lake's hydrology is largely influenced by the Cumberland River, with a small portion of the inflow coming from the Martins Fork River. The lake's surface flow is primarily dependent on rainfall and snowpack. Agriculture is not a significant factor in the area, but the lake supports a variety of recreational activities, including fishing, boating, and camping. The lake is home to several species of fish, including bass, crappie, and catfish, making it a popular destination for anglers. Overall, Martins Fork Lake provides a valuable source of water for the surrounding communities and serves as a popular recreational destination.

FAQ

About Martins Fork Lk At Martins Fk Dam Nr Smith

Where does the data for Martins Fork Lk At Martins Fk Dam Nr Smith come from?

Daily storage, pool elevation, and release rates are sourced from USGS, USBR, and USACE monitoring stations. Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.

What does the Hazard hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this reservoir, set a threshold, and you'll get a push the moment conditions cross.
