8 lakes doing something unusual this week, from Lake Powell to Sam Rayburn Reservoir

Out of the 101 lakes we follow, these 8 are the ones moving hardest right now: record levels, feet of water gained or lost, sharp temperature swings and the strongest wind. The numbers, and what to do with them.

Every week a few lakes break out of the normal range. Here are this week's. Ranked by how far each one is from normal, with a line on the fishing at each.

  1. 1
    Lake Powell seen from plane

    Lake Powell, UT

    Lake Powell: up 20 ft in 30 days +20 ft 30 days

    Lake Powell has risen 20 ft in 30 days, 4.8 ft of it this week. At 61°F, striped bass are the bet here. Watch for birds and surface feeding. Start at a point drop-off in 4 to 16 ft; try swimbait or live shad where bait is. The lake sits 43 ft below its usual level, so fish crowd onto fewer points and short ramps may not reach the water. Go Thursday (good bite).

    Sam Rayburn Reservoir

    Sam Rayburn Reservoir, TX

    Sam Rayburn Reservoir: lowest since at least 2016 152.7 ft record low

    Sam Rayburn Reservoir reads 152.7 ft, at the bottom of a record that starts in 2016, 8.7 ft below normal for the season. At 65°F, largemouth bass are the bet here. They chase baitfish into creeks and coves. An upper arm in 24 to 28 ft is the place to begin; try small jig or minnow under a float. The lake sits 8.7 ft below its usual level, so fish crowd onto fewer points and short ramps may not reach the water. Thursday rates good for the bite.

    Lake Hartwell, SC

    Lake Hartwell: lowest since at least 2016 647.6 ft record low

    Lake Hartwell reads 647.6 ft, at the bottom of a record that starts in 2016, 8.4 ft below normal for the season. The water is 65°F and striped bass are in range. Start at a wind-blown bank in 4 to 16 ft; try swimbait or live shad where bait is. The lake sits 8.4 ft below its usual level, so fish crowd onto fewer points and short ramps may not reach the water. Saturday rates good for the bite.

    Detroit Lake, OR

    Detroit Lake: down 18 ft in 29 days −18 ft 29 days

    Detroit Lake has fallen 18 ft in 29 days, 3.8 ft of it this week. The water is 50°F and trout are in range. Near the surface and along shorelines. A point drop-off is the place to begin; try spinner or spoon, troll slowly. The lake sits 6.8 ft below its usual level, so fish crowd onto fewer points and short ramps may not reach the water. Thursday rates good for the bite.

How to read these numbers

A record low or high is measured against the daily readings we hold for that lake, which start around 2016, not against the lake's whole history. A fast rise usually means heavy rain or dam releases upstream; a fast drop is usually a managed drawdown. Temperature swings come from the weather over the lake, not from the lake itself.

Each lake page carries the full chart and today's bite outlook. Levels and temperatures update daily; the wind figures are forecasts and can change.

Before you go

A lake at the extremes is a lake where the ramps, the hazards and the fish are not where they usually are. Check the lake page before you tow, and if the water is cold, wear the life jacket.
