Apple Creek Nonpoint Source Watershed - Nine Key Element Plan

Purpose

The Apple Creek Watershed is a subwatershed of the Lower Fox River Basin and is located in east central Wisconsin in Outagamie and Brown Counties. Apple Creek empties into the Fox River near Wrightstown, WI, draining approximately 33,190 acres. Excessive sediment and nutrient loading to the Lower Fox River and Bay of Green Bay has led to increased algal blooms, oxygen depletion, water clarity issues, and degraded habitat. Algal blooms can be toxic to humans and costly to a local economy. The purpose of this project is to develop an implementation plan for the Apple Creek subwatershed to meet the requirements of the TMDL. The Lower Fox River TMDL requires that any tributaries to the Lower Fox River meet a median summer total phosphorus limit of 0.075 mg/l or less. A median total suspended solids limit has not been determined for tributaries but is set at 18 mg/l for the outlet of the Fox River.

Objective

Goal #1: Improve surface water quality to meet the TMDL limits for total phosphorus and sediment. Goal #2: Increase citizens’ awareness of water quality issues and active participation in stewardship of the watershed. Goal #3: Reduce runoff volume and flood levels during peak storm events. Goal #4: Improve streambank stability and reduce amount of streambank degradation.

Outcome

Meeting the goals for the Apple Creek watershed will be challenging. Watershed planning and implementation is primarily a voluntary effort with limited enforcement for “non-compliant” sites that will need to be supported by focused technical and financial assistance. It will require widespread cooperation and commitment of the watershed community to improve the water quality and condition of the watershed. This plan needs to be adaptable to the many challenges, changes and lessons that will be found in this watershed area as implementation moves forward.
