Parsons Creek TMDL

Purpose

Parsons Creek is currently being impacted by sediment, phosphorus, and ammonia. Due to excessive inputs of sediment and nutrients, Parsons Creek is experiencing degraded habitat, sedimentation, and aquatic toxicity due to high ammonia levels. On the 2006 303(d) Impaired Waters list, Parsons Creek is listed for the following: (1) Pollutants: Sediment, Nutrients (phosphorus, ammonia) (2) Impairments: Sediment, Degraded Habitat, Aquatic Toxicity (ammonia)

Objective

The goal of the Parsons Creek TMDL is to reduce sediment, ammonia, and phosphorus loads to a level sufficient to meet the narrative water quality standard (WQS) and the stream’s designated uses.

TMDL (USEPA) Approved
EPA finds that the TMDL for Parsons Creek watershed satisfies all of the elements of an approvable TMDL. This TMDL approval addresses 8 TMDLs for 4 waterbody segments and 9 impairments from the 2006 and upcoming 2008 Wisconsin 303(d) list.
TMDL Implementatoin
An implementation plan for Parsons Creek should be developed and implemented to remove the Creek from the 303(d) impaired waters list. This TMDL addresses 8 TMDLs for 4 waterbody segments and 9 impairments from the 2006 and upcoming 2008 Wisconsin 303(d) list.
