Maquoketa River Floodplain Connectivity Research reports Report on research that has shown that management of river connectivity of channels to floodplains is an effective mitigation strategy to remove nutrients, sediment, and carbon from river flows. The confluence of the Maquoketa and Mississippi Rivers is a unique site because: 1) the Maquoketa River carries some of the highest documented sediment and nutrient loads in the Upper Mississippi River (Garrett 2013, Robertson et al 2009); 2) the delta at the confluence with the Mississippi River is heavily managed by a State-Federai-NGO partnership and includes several Habitat Rehabilitation Projects designed to enhance fish and wildlife production and recreational access; 3) a recent nonreparable break in the levy near...

Floodplains provide the ability to remove and sequester, sediments, nitrogen, phosphorus, and carbon; however effectiveness of floodplains is limited by the extent and connection of the floodplain to the river. The confluence of the Maquoketa and Mississippi Rivers presents a unique study location because the delta at the confluence is heavily managed by a State-Federal-NGO partnership that has already taken action focusing on evaluating the impact of increased connectivity on numerous ecosystem services, including...

Effectiveness of floodplains in providing these services is dependent on the extent and location of connection between floodplain and river. Tributary loading of sediments, nitrogen and phosphorus to the Upper Mississippi River contribute to the development of river and coastal eutrophication as well as hypoxic conditions in the Gulf of Mexico. Recent research has shown that management of river connectivity of channels to floodplains is an effective mitigation strategy to remove nutrients, sediment, and carbon from river flows.
