This project will complete a Total Maximum Daily Load Implementation Plan for the watersheds of Big Sandy and Minnewawa Lakes. This restoration plan will provide pollution reduction and watershed management strategies that are developed with input from stakeholders in the watersheds.
The goal of this project is to construct, calibrate, and validate five Hydrologic Simulation Program FORTRAN (HSPF) watershed models. The outcome will be HSPF models that can readily be used to provide information to support conventional parameter TMDLs. These models will generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will focus on creating a watershed identity, monitoring & assessment, stressor ID assistance, Total Maximum Daily Load (TMDL) report development, Watershed Restoration & Protection Strategy (WRAPS) report development, watershed prioritization and targeting, and the continuation of the Civic Engagement components of the project. Currently, this watershed has seven listed conventional impairments (Lake Eutrophication); however, it is possible that additional stream impairments (up to four) may be identified during the IWM process.
