The Beaver Watershed Alliance (“BWA”) announced an acquisition of a Clean Water Act Section 319 Grant for use in the Beaver Lake Watershed to:
- Model flooding hot spots.
- Develop riparian management plans.
BWA states that it will be working with Olsson to develop a 2-D HEC-RAS model for the entire Beaver Lake watershed.
The model will also:
… build on previous studies and local data to improve clarity around stormwater and flooding challenges and ultimately produce a user-friendly GIS tool that communities and watershed partners can use to inform planning and project prioritization.
BWA states that project goals for the model include:
- Establishing a Work Group of local water professionals to guide model development.
- Developing a GIS-based tool to identify stormwater and flooding hotspots and prioritize mitigation projects.
- Identifying areas where additional study or funding may be needed.
- Testing potential land use and watershed changes to understand impacts on stormwater capacity and flooding in municipal systems.
- Supporting regional planning and resource prioritization.
- Contributing data and insights to the Arkansas State Flood Plan.
