Connections at Shingle Creek
Projects and Practices 2014
The Impaired Biota and
DO TMDL identified both TMDL load reducing actions and actions to improve non-TMDL parameters, and specified that both would be
necessary to achieve state water quality and biotic integrity standards and to restore more natural form and function to Shingle Creek and its corridor. This project will stabilize streambanks, reducing excess sediment contribution from bank mass wasting. A native buffer will filter runoff
from adjacent developed uses, reducing nutrient and sediment flow to the stream. Structures added to the stream will increase aeration, raising dissolved oxygen levels. Improved water quality and habitat enhancement will reduce stress on aquatic organisms and provide conditions for an improved biota.
This project resulted in estimated reductions of 2 lb. of phosphorus per year and 11 tons of sediment per year
LOCAL LEVERAGED FUNDS
This project is the ecological restoration of 1,400 feet of Shingle Creek, an Impaired Water for low dissolved oxygen and impaired biota, in Brooklyn Center and Brooklyn Park. The Shingle Creek Impaired Biota and Dissolved Oxygen Total Maximum Daily Load requires sediment oxygen demand load reductions and establishes restoration design standards to enhance habitat that will be incorporated into this project. By adding rock riffles, this project will increase stream reaeration and raise dissolved oxygen concentrations; enhance and add in-stream and near-stream habitat for macroinvertebrates and fish; stabilize eroding streambanks that are contributing sediment and nutrients to the Creek; and modify the stream bed to provide for a low-flow channel to carry an ecological base flow.
