Watershed Assessment

The MWMO’s watershed assessment and research activities seek to develop a scientific base of knowledge that characterizes physical, chemical, cultural, historic, biological, social, economic, organizational and political resources of the MWMO to guide planning and management decisions in the watershed.


Watershed Modeling

The MWMO is in the process of developing comprehensive models for all of the subwatersheds within its boundaries. These models will be used to help identify the most effective locations in the watershed to implement both flood control and water quality improvement projects.

Kasota Ponds Wetlands: Summary of MWMO Monitoring Activities 2008–2017
2019 (PDF, 4.6 MB, 52 pages)

The Mississippi Watershed Management Organization has been monitoring the water quality of three wetlands, collectively called the Kasota Ponds, since 2008. The purpose of this report is to compile and summarize the data that have been collected from the Kasota Ponds wetlands thus far and to recommend future monitoring and/or restoration activities that could help improve the wetlands as a source of urban wildlife habitat.

Towerside District Stormwater System Phase I Report
2018 (PDF, 23 MB, 39 pages)

This is an analysis on the effectiveness and efficiency of the design and planning process for the Phase I Towerside District Stormwater System occurring between 2013-2016. Also included are proposed adjustments and recommendations to improve the design, planning, contractual and policy process on future projects. This project builds on the existing Green 4th Street concept design study in the heart of the Towerside Innovation District. This is a continuation of MWMO efforts, to utilize an integrated systems based approach to manage stormwater as an asset in a fully developed urban setting.

A Guide to Bank Restoration Options for Large River Systems: Part II Bioengineering Installation Manual
2010 (PDF, 8 MB, 91 pages)

The Mississippi Watershed Management Organization has developed a guidance document and planning software for bank restoration on large river systems. Physical characteristics of the riverbank, along with predicted shear stresses across a full range of flows, are used to classify and recommend bio-engineering applications that restore and protect the riverbanks of the Mississippi River.
