Located within the Township of Murray and the City of Trenton, this 1150 hectare watershed drains into the Bay of Quinte (Map 1). This report, initiated by the Lower Trent Region Conservation Authority in September 1995, is the first phase of the Dead Creek Subwatershed Plan. 1.1 REGIONAL CONTEXT The arrival of colonists in the late 1700's to the Bay of Quinte area, one of the oldest, settled rural areas in Ontario, marked the beginning of dramatic cultural changes to the natural landscape (QRAP, 1990). Over the years, the natural shoreline has progressively become more developed as a result of urban, industrial, and agricultural activity. The many rivers and streams in the Quinte area act as pathways for the disposal of by-products of this human activity into the Bay. The result has been a degraded ecosystem affected by excessive nutrient enrichment, bacteriological and heavy metal contamination and habitat loss (QRAP, 1990). In 1975 the International Joint Commission identified the Bay ofQuinte as an area of enviromnental concern (QRAP, 1990). The Bay of Quinte Remedial Action Plan was developed to provide recommendations for the reduction of contaminant loading to the Bay, thereby improving, enhancing and protecting the Bay's ecosystem· and the surrounding land (QRAP, 1993). As the population around the Bay of Quinte is expected to grow at an annual rate of 1.1 percent to the year 2001 (QRAP, 1993), changes in land use, especially urban growth, can be expected. Continual intensification of development can aggravate a number of environmental problems, including water quality concerns (Ministry of Environment and Energy (MOEE), 1991). In order to address environmental concerns relating to urbanization, the QRAP (1993) identified the following recommendation in the Stage 2 Report - Time to Act: The province of Ontario's Subwatershed Planning Process should be adopted and employed by Quinte area municipalities to provide direction for the preparation of Secondary Official Plans for areas slatedfor new urban development.
