Frequently Asked Questions
- What is the concern with Antelope Creek?
- The water quality in a stretch of Antelope Creek, starting at the outlet of Holmes Lake Dam and extending to Salt Creek, contains elevated levels of E. Coli bacteria, andammonia that are considered to cause impairments to everyday uses of the Creek.
- Antelope Creek Land Uses and Pollution Sources
- What regulatory elements are involved with Antelope Creek?
- The Nebraska Department of Environmental Quality (NDEQ) has recently placed this reach of Antelope Creek on its listing of impaired waters, as the current water quality in the stream does not meet the standards of its state assigned beneficial use. NDEQ determines a level of pollutants which is considered acceptable for the intended use of the stream, and at that level is referred to as the Total Maximum Daily Load (TMDL).
- What is the 303(d) List?
- The federal Clean Water Act requires states to prepare a list of impaired surface waters, or those which do not support their assigned beneficial uses. This list is referred to as the 303(d) List of Impaired Waters.
- What are the assigned beneficial uses?
- NDEQ has listed primary contact recreation, aquatic life, agricultural and industrial water supply, and aesthetics as assigned beneficial uses of Antelope Creek.
- What is a TMDL?
- Total Maximum Daily Load (TMDL), established by NDEQ, includes the pollution control goals and strategies necessary to improve the quality of impaired waters and remove the identified impairments. Surface water sampling is used to establish baselines for TMDLs.
- What will the Antelope Creek Watershed Basin Management Plan do to improve water quality?
- The Basin Plan will serve as a tool for the City and NRD staff, as well as other planning and design engineers, to proactively forecast, evaluate, and manage stormwater quality impacts through identification of structural and non-structural Best Management Practices (BMPs).
- What are Stormwater Best Management Practices (BMPs)?
- Stormwater BMPs are control measures that aim to reduce the amount of pollutants (quality) and decrease the total flow of stormwater (quantity) in urban runoff caused by changes to land use.
- How is the Antelope Creek Watershed Basin Management Plan different than the Antelope Valley Project?
- The Basin Plan focuses on improvement of water quality in the Creek through reduction of pollutants in stormwater runoff. The Antelope Valley Project focused on infrastructure improvements to reduce the threat of flooding in the City, improve transportation, and create recreational and economic development opportunities.
- How can those living in the Watershed help improve water quality in Antelope Creek?
- Basin Plan strategies to improve water quality will include both structural and non-structural solutions. The success of non-structural solutions, such as switching to low or non-phosphorus fertilizers, cleaning up after pets , and others, is largely based on how well those living in the watershed implement these strategies.
- When will the Basin Plan be completed?
- The planning effort began in May 2010 and is anticipated to be complete around September 2011, with a draft plan anticipated to be ready during the Summer of 2011.
