Martin Branch, Martinville Creek and Rogers Branch TMDLs

Purpose

Martin Branch, Martinville Creek, and Rogers Branch are impaired streams in the Grant-Platte River Basin in southwestern Wisconsin (Grant County). The Wisconsin Department of Natural Resources (WDNR) placed a number of stream segments from each stream on the Wisconsin 303(d) impaired waters list as high priority due to degraded habitat caused by excessive sedimentation (the deposition of sediment) and low dissolved oxygen caused by high phosphorus concentrations. Due to excessive sedimentation in Martin Branch, Martinville Creek, and Rogers Branch and excessive phosphorus in Rogers Branch, these waterbodies are not currently meeting applicable narrative water quality criterion as defined in NR 102.04 (1); Wisconsin Administrative Code.

Objective

By implementing measures to reduce the sediment and phosphorus loading, the TMDL will address degraded habitat and low dissolved oxygen (DO) impairments in the watersheds.

Outcome

To address the sediment load in the waterbodies, WDNR determined that an instream concentration of 10 mg/l for total suspended solids (TSS) would meet the narrative criteria of no objectionable deposits of sediment in the streams. This target was based upon achieving significant reductions during high flow conditions (when loads are proportionally the greatest), and best professional judgment of WDNR (Page 17 of the TMDL document).
