Effects of Flood Inundation and Invasion by Phalaris arundinacea on Nitrogen Cycling in an Upper Mississippi River Floodplain Forest data This data set consists of monthly averages of soil and litter properties. Rows are grouped in the following order: year, month, vegetation type, plot ID. Within a single month five plots were sampled within each of the 2 vegetation types (10 plots total). Columns F+ represent individual measurements.

The density of each species of submersed aquatic vegetation (SAV), and of all species combined, are scored based on the amount of plant material collected on the teeth of each rake. Plant density (PD) scores are ordered and vary from 0 (no plants captured) to 5 (80-100% of rake teeth covered). The PD score of 1 has represented the vast majority of all non-zero values since 1998 and is associated with a wide range of biomass (e.g. <1g to 694g fresh weight in Pools 4 and 8 during the 2017 field season).

Missingness is typical in large datasets, but intercomparisons of interpolation methods can alleviate data gaps and common problems associated with missing data. We compared seven popular interpolation methods for predicting missing values in a long-term water quality data set from the upper Mississippi River, USA.

(2016), and 3) LTRM vegetation data (1998 – 2017). Two field studies were completed in 2017. The first targeted SAV biomass in raked plots and was conducted in collaboration with USFWS annual Lake Onalaska Vallisneria americana monitoring. In the second study, fresh weights of raked SAV were recorded at approximately 10% of LTRM Pools 4 and 8 2017 sampling sites.

Data was collected via the Long Term Resource Monitoring element of the U.S. Army Corps of Engineers’ Upper Mississippi River Restoration program and the Illinois Natural History Survey’s Long-Term Survey and Assessment of Large-River Fishes in Illinois.

The goal of this sampling effort was to document inundation through space and time at a limited number of sites but across the range of flow conditions experienced throughout the 2017 growing season. We used temperature data loggers (Onset HOBO Pendant Temperature Data Loggers, model #UA-001-08) to record hourly ambient temperatures at the floodplain’s surface for subsequent analysis of hourly and diurnal flux patterns that would indicate likely submergence. Temperature loggers were deployed in two separate sites within six study segments (Pools 4, 8, 13, 26, La Grange,...

The lack of these habitats likely influences water quality, nutrient processing, and communities of organisms. In early 2016 a major flood event breached two levees south of Cape Girardeau, MO resulting in the creation of two new backwaters. Water quality, metabolic rate, and fish community data were collected from the new backwaters as well as an isolated floodplain lake.

Over a 20-year period (1998-2017), the off-channel (i.e. backwater) areas in upper Pool 4 remained chronically turbid and supported a limited submersed macrophyte community with high between-year variability in the proportion of sites where submersed plants were observed. Water surface elevation and discharge rates also fluctuated substantially within- and between-years in the upper pool. Pearson correlation analysis indicated that between-year change in the proportion of sites where submersed macrophytes...

To study the response of Illinois Waterway water quality and fish community, ongoing water quality and fish Long Term Resource Monitoring (LTRMP) elements of the Upper Mississippi River Restoration program were expanded from the La Grange reach of the Lower Illinois to eight pools and reaches of the entire Illinois Waterway. This multi-agency effort occurred in each year before (2019), during (2020), and after (2021) the extended lock and dam closure.

Studies have shown that rotifers are a common prey for invasive bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix) as well as native fishes of the UMR and there is concern these invasive carp will compete with native fishes for food resources. This study was conducted to provide baseline rotifer community data before range expansion of these invasive carps into the upper reaches of the UMR. Vertical tows were taken to collect rotifer samples over a four year period in Lake Pepin, a natural riverine lake in Pool 4 of the UMR.
