The goal of this project is to apply the Hydrological Simulation Program FORTRAN (HSPF) model to evaluate scenarios to support potential management actions and implementation in the watershed, construct Total Maximum Daily Load (TMDL) studies, and to develop a conceptual site model of the lakes for understanding phosphorus release.
On behalf of the Metropolitan Council, Environmental Financial Group Inc. generated a matrix of water conservation programs with detailed information about the costs and benefits of the programs. Tools were also developed to allow users to calculate potential water savings, estimate program implementation costs, and test the effects of various water conservation programs and rate structures.
This project will construct, calibrate, and validate an HSPF watershed model for the Zumbro River watershed. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs). The consultant will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
The consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
The goal of this project is to finalize the draft Lake Pepin Total Maximum Daily Load (TMDL) Report, issue it for public comment, address comments, and finalize the report. Lake Pepin is impaired by high levels of nutrients that cause excessive growth of algae. High levels of sediment, carried in by major river systems, also affect the lake. The sediment is filling in the lake at a much faster rate than before Minnesota was settled and intensely farmed. Nutrients and sediment are distinct yet inter-related pollutants, and are being addressed in separate TMDL reports.
The MPCA has selected the Soil and Water Assessment Tool (SWAT) watershed model to simulate watershed hydrology and water quality to assess various restoration scenarios in the Little Cannon River watershed. The SWAT model is an important tool in developing an understanding of existing conditions and simulating conditions under various management scenarios to inform the development of implementation strategies and plans to restore and protect streams and lakes.
The goal of this project is to complete the construction, calibration, and validation of a Hydrological Simulation Program – FORTRAN (HSPF) watershed model for a portion of the Mississippi River-Lake Pepin watershed.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
The Metropolitan Council, in conjunction with CDM Smith and HKGi consultants, reorganized and expanded the water conservation tools on the water supply planning pages of the Metropolitan Council’s website. The revised toolbox was organized into an online, web-based guide format. These tools are supplemented with fact sheets and case studies that serve to educate and provide useful information to support water conservation programs and activities.
The goal of this project is to test the sensitivity of the Zumbro River Watershed Hydrological Simulation Program FORTRAN (HSPF) model management scenario results. Additional goals are to develop Total Maximum Daily Loads (TMDLs) for impaired stream reaches and Rice Lake, which will be documented in a TMDL Report. The consultant will apply the existing calibrated and validated Zumbro River Watershed HSPF model to construct load duration curves to develop TMDLs.
