Greer's Ferry Lake is 8.4 feet above power pool. The Army Corps of Engineers has been running two units usually starting from 7am to 7pm. But it's subject to change. Always check the USACE Little Rock app for the generation schedule before heading out. With the current generation schedule the bite has been good fishing the falling water in the morning.
I've been putting in at Lobo Landing access and starting a little early to beat the new batch of water that hits in the afternoon. Afterwards I've been putting in at the Dam for the second half of the day and fishing a deep water nymph rig. Set the indicator at various depths depending on how deep the water is. Anywhere from 6 ft to 12 ft deep with a split shot to get it down.
Hot flies for this technique are San Juan worms and egg patterns along with Caddis, Pheasant tail nymphs or anything buggy. The Streamer bite has been good. Try fishing sink lines on your streamer rod with articulated patterns and pound the bank.
