We then drove on to the Osborne nature center, where they have a display pen with some elk and buffalo.
#VOGLA RIVER IOWA SERIES#
They are abandoned due to a series of floods, most recently in 1999. There is a street there on river left near a row of abandoned houses. We dropped Carl's car off in Littleport, just downstream from the bridge. Fishing would have been tough, as the river was high, and fish-holding structure would have been tough to identify in these conditions. Although we brought fishing gear along (as the Volga is supposed to contain a good population of "small" smallmouth bass), we never even made a cast- Just enjoyed the scenery and wildlife. It is normally a very small river, and "high" means flowing about 4 or 5 feet deep according to the somewhat unofficial measurement of dipping the paddle blade down to the bottom occasionally. High is a relative term though, when speaking of the Volga River. The river was flowing high, fast, and cold. It was a beautiful day with a sunny sky and highs in the 60's. It's been a very long, cold winter, and it was time to get out. Tributary inflow was not accounted for during this analysis.Carl and I were anxious to get out on the first paddling trip of the year. Flows on the Mississippi River were of the coincident frequency event on the Iowa River. The stages correspond to annual chance exceedance events according to the 2009 USACE Iowa River Regulated Flow Frequency Study Final Report at the Wapello, IA gage. Iowa River flood inundation mapping near Oakville, IA is based on the stage at the Oakville, IA gage. Tributary inflow was not accounted for during this analysis. Iowa River flood inundation mapping near Wapello, IA is based on the stage at the Wapello, IA gage. Iowa River flood inundation mapping from Highway 70 to upstream of Wapello, IA is based on the stage at the Columbus Junction, IA gage. Tributary inflow was only accounted for during this analysis downstream of Iowa City. Top of levee elevations from the National Levee Database were incorporated into levee systems along the Iowa River. The discharges correspond to annual chance exceedance events according to the 2009 USACE Iowa River Regulated Flow Frequency Study Final Report. Iowa River flood inundation mapping downstream of Coralville reservoir to Columbus Junction is based on reservoir releases. Coralville Lake Coralville to Columbus Junction The downstream inundation extent was set at Highway 65. Top of levee elevations from the National Levee Database were ncorporated into levee systems along the Des Moines River. The only tributary inflow accounted for during this analysis was the Raccoon River. The releases correspond to annual chance exceedance events according to the USACE Des Moines River Regulated Flow Frequency Study, 2019 Regulation Plan Update. Saylorville Lake Downstream of Saylorvilleĭes Moines River flood inundation mapping downstream of Saylorville is based on releases from Saylorville Reservoir. Top of levee elevations from the National Levee Database were incorporated into levee systems along the Des Moines River. Downstream to Mouthĭes Moines River flood inundation mapping downstream of Lake Red Rock is based on releases from Red Rock Reservoir. The upstream inundation limit was set at Highway 65. The inundation boundaries were generated using 3m Iowa LiDAR, and the edges were generalized for appearance. Des Moines River flood inundation mapping for Lake Red Rock pool is based on a water surface elevation.
