Toms Creek Watershed Study



As a member of the Upper Neuse Basin Association (UNRBA), it is in the best interest of the Town of Wake Forest (TOWF) to have a water quality model that can be utilized to support a watershed plan for Horse Creek. 

The model will be used in tracking compliance with the Falls Lake Nutrient Sensitive Waters (NSW) requirements, and in specifically with the UNRBA’s Interim Alternative Implementation Approach (IAIA) to the NSW strategy. 

The model will be developed for the closest approximation of the Wake County portion of the Horse Creek watershed that is consistent with the subwatersheds utilized for the UNRBA’s Watershed Analysis Risk Management Framework (WARMF) watershed model in order to make meaningful comparisons of projected pollutant loads.  The Watershed Treatment Model (WTM) will calculate annual watershed loads for nitrogen and phosphorus for existing conditions, including nutrient load reductions from existing structural and non-structural stormwater management practices (where pertinent data are available). 

By default, the model will also generate annual loads for fecal coliform bacteria and total suspended solids, should the Town ever seek to utilize that information.
