The surface water temperature at the dam is 45° F with the lake elevation at 3253.5 which is 2.7 feet lower than the elevation last year on this date and 11.5 feet below normal full pool capacity. Inflow into Lake McConaughy is 1,413 cfs with a recently reduced outflow of 615 cfs. The lake surface elevation has increased 0.2 foot in the past week.
Daytime spring success by boat anglers targeting walleye continues to be very limited to date. Most of the effort has been from Martin Bay west to near North Shore Lodge vertically slabbing in 40-50 feet of water or casting into shallower water with jigs or crankbaits. Angler pressure for walleye at night along Kingsley Dam has increased as the spawning run is heading into the second week. Success has been good with most fish in the 16-20 inch range with some larger fish up to 12 pounds. Boat anglers on the dam face are trolling large crankbaits and bank anglers are casting crankbaits or jigs. It should be noted that all boats are prohibited within 200 feet of the Kingsley Dam outlet and morning glory structures. The statewide daily bag limit for walleye is 4 fish with minimum size limit of 15 inches and no more than one fish over 22 inches.
An increase in water temperature should help bank anglers targeting wipers in Martin Bay who have had little success to date.
Channel catfish success in the area near Otter Creek, and west, has been slow and limited to mostly bank anglers. Most anglers have been using shad entrails, cut-bait or frozen shrimp baits.
Usable concrete boat ramps for launching could be found at the Cedar Vue lakeside and bayside ramps, Lemoyne Bay, Arthur Bay, Martin Bay, Spillway Bay and Lakeview ramps. Boats could also be launched with four wheel drive vehicles from the beach at North Shore Lodge.
The surface water temperature is 47° F. Rainbow trout fishing success has been fair for bank anglers using worms, salmon eggs, dough baits or casting spinners, spoons or jigs. Most fish caught range in size from 10-12 inches with an occasional larger fish up to 16 inches. Boat anglers are trolling or casting spinners or spoons. Fly fishermen have been using bead head nymph patterns or streamers. Anglers are reminded the daily bag limit in Lake Ogallala is 5 trout with no more than one over 16 inches.
Discharge into the canal has been reduced to a flow of 580 cfs. Success for rainbow trout has been fair with some larger fish in the 16-18 inch range. The most popular technique has been drifting salmon eggs, worms or dough baits. The daily bag limit for the Keystone Canal is 5 trout with no size limit.
North Platte River below the Keystone Diversion Dam
A minimum flow release of 35 cfs exists from the Keystone Diversion Dam into the river Success for rainbow trout has been slow with most anglers using worms, salmon eggs, dough baits or casting spinners or spoons. Fly fishermen have been using weighted nymph patterns, streamers or midge patterns. Anglers are reminded the daily bag limit in the North Platte River below the Diversion Dam is 5 trout with no more than one over 16 inches.
