Hickory Creek Watershed: Implementing a Watershed Protection Plan (WPP)

Initiation of best management practices implementing the Hickory Creek WPP.


Hickory Creek is a predominantly rural watershed. While it is currently meeting designated uses, it is under significant development pressures. Hickory Creek serves as a good example of conditions in the larger Lake Lewisville watershed, which is also under substantial development pressures.

More than one assessment of water quality has highlighted nutrient concerns throughout the lake’s watershed. Modeling at the sub-watershed level and associated research during development of the WPP indicated that future development could degrade water quality and threaten beneficial uses like fishing or water supply.

To address nutrient concerns and minimize adverse effects of development, the City of Denton prepared a watershed protection plan (WPP) for Hickory Creek.

Project Description

This project installed four structural best management practices (BMPs). The number of sites and the BMPs were selected based on the size, cost, estimated pollutant-load reductions, and the specific site conditions related to each BMP considered. The project used a combination of natural treatment techniques along with proven nutrient- and sediment-removal structures. The city also made code modifications and initiated partner collaborations to protect the watershed for years to come.
