The 2009 - 2010 instream flow study that RCWA worked on with the Tennessee Wildlife Resources Agency (TWRA) generated a Letter of Request that was recently submitted to the Tennessee Department of Environment and Conservation. The letter reports the withdrawal as an "identifiable source of degradation," and adds that "both the low-head dam and excessive withdrawal during low flow periods contribute to pollution on Richland Creek." TWRA is a comment agency and recommendations focus on the protection of fish and aquatic habitat and diversity. (The low flow periods refers to the summer months)
RCWA requested a meeting with all of the involved agencies and departments to discuss the research and long-term restoration of Richland Creek. At this May 24th meeting RCWA presented many potential benefits to the stream's ecology, integrity, hydrology and water quality by removing the low-head dam. Acknowleging the inevitable costs a project like this would entail, RCWA also suggested potential funding resource ideas and willingness to help. At this time, TDEC and Metro are discussing the report.
Produced by the Ohio Department of Natural Resources, here is a link to a short (8 minute) video showing a low-head dam removal and commentary about benefits to the stream's ecology and integrity -- http://www.dnr.state.oh.us/tabid/21463/Default.aspx. Take a look...the low head dam being removed is similar to the one on Richland Creek with parallel benefits.
RCWA was invited to produce and present a wall poster (below) at the Instream Flow Council's Flow 2011 conference held at the Maxwell House Hotel in Nashville, May 2-4 about our flow study partnership with the TWRA. Click on the poster to enlarge for easier viewing.
Long-term restoration and sustainaibliy of Richland Creek is the mission of the Richland Creek Watershed Alliance.
