Plum Creek: Implementing a Watershed Protection Plan (WPP) - Illicit Discharge Monitoring

Guadalupe-Blanco River Authority (GBRA) monitored the City of Lockhart's stormwater conveyance system for illicit discharges.

Background

From 2004 through 2008 Plum Creek was listed as impaired because of bacteria that exceeded the contact recreation standard and concerns for nutrients in the lower reaches. In 2008 the Plum Creek WPP was approved. Since 2009 management measures have continued to be implemented.

Project Description

One management measure in the Plum Creek WPP is to detect and address non-stormwater discharges into the municipal separate storm sewer system. GBRA monitored the City of Lockhart's stormwater conveyance system for illicit discharges during dry weather. When water was present under those conditions and water quality sampling identifies an illicit discharge, the City of Lockhart was notified to enforce the city's drainage ordinance.
