North American Midcontinent Rift Zone
Overview All gauges Around the high number = below dams. Mid range = fish spread throughout. Around the low number = impoundments above dams or deeper pools downstream. Water clarity improves with stability.

Des Moines Saylorville Lake 840ft. - Below this level expect bait on shoreline flats during late summer with an on-shore wind. Above this level bottlenecks, etc. become more important.
gravel flats, rip-rap features; largemouth bass, common carp, channel catfish, freshwater drum, white bass/wiper
stable, low - Wind, speedboats, algae blooms cloud the water.
stable or falling, mid-level - decent clarity
rising, mid level - Silt carried down the river clouds the water.
stable, high - decent clarity with some algae bloom upstream.
Des Moines Saylorville Tailwaters Above 8.25 ft. the rock bar at the mouth of the emergency spillway is submerged and a kayak can reach the main backwater from Cottonwood Pier. 4.75ft. approximates Chad's number of 1800 cf/s. Expect more fish, but less access above this number, fewer fish, but better access below. gravel bars, rip-rap features; smallmouth bass, freshwater drum, common carp, white bass/wiper, walleye, catfish.
Des Moines Lake Red Rock
744 - 746ft. - Whitebreast creek above hwy. 14
746 - 750ft. - Competine creek floods Kennedy road on the south side of the lake.
750 - 755ft. - Low-lying areas up Teter, Brush, Calhoun, Prairie, Walnut and several unnamed creeks begin flooding.
755 - 760ft. - Red Rock flows backward into Robert's Creek lake. Robert's and Wildcat creeks begin flooding Dubuque Rd. Levees topped around waterfowl ponds near the towns of Runnells, Hartford, and Swan.
760 - 765ft. - hwy. 5 bridge over the South River.
782ft. - G28 floods near Brush Creek bridge, by now the situation is quite severe and should be avoided.
Sandstone bluffs, but the water clarity and fly fishing action improves in flooded creek arms. Flooded grass attracts frogs, baitfish, hatchling buffalo and carp - these, in turn, attract; shortnose gar.
Gravel roads such as Dubuque Rd. and Gear St. often dead-end near the flood plain offering some degree of carry-down access.
Flood water involves dangers such as collapse of beaver dams, masses of floating logs and debris, current straining through culverts and fence lines, stranded snakes, rodents, spiders boarding your craft - avoid current, unnecessary contact with trees and plants, observable dangers like power lines, etc.

Overview All gauges Most of these rivers have trout in their upper sections and/or are fed by trout streams. Smallmouth bass, rock bass, native suckers, common carp, walleye, and northern pike become more numerous downstream. Features vary, but there is comparatively more limestone and deep clay pools and less gravel/glacial rock and sand.
Mississippi Lansing (Pool 9), Mc Gregor (Pool 10), Dubuque (Pool 12), Camanche (Pool 14), Muscatine (Pool 17) Calm, weedy areas of main pools and backwaters attract; grass carp, common carp, largemouth bass, bowfin, shortnose gar, longnose gar. Dams, spillways, pumping stations and other rip-rap features attract the species above and; smallmouth bass, northern pike, walleye, sauger, yellow bass, white bass, freshwater drum, catfish.
