mandated to consult with ODFW to mitigate adverse impacts for all developments closer than 300 feet (Josephine County Rural Land Development Code 1994). Josephine County Public Works is responsible for maintaining county roads and public right of ways and road drainage ditch systems. This agency also works with ODOT to maintain several bridges in the watershed. It follows riparian management guidelines as presented by the permitting process with DSL and ODOT’s Water Quality and Habitat Guide when conducting maintenance activities in sensitive areas. State Level Josephine Soil and Water Conservation District SWCDs help landowners and farmers plan and implement water and soil conservation measures, while working cooperatively with watershed councils and other natural resource management agencies. Oregon Department of Forestry ODF enforces the 1971 Oregon Forest Practices Act on all non-federal lands. The Act includes policies that set requirements for timber harvest and regeneration with regards to wildlife habitat, fish habitat, and water quality. Stream protection and riparian setback requirements are determined by whether fish and/or domestic water use is present in adjacent streams. Oregon Department of Agriculture ODA is responsible for overseeing agricultural activities in the state. Under Senate Bill 1010, ODA is designated as the lead agency to address non-point source pollution related to agriculture. It is currently developing an Agricultural Water Quality Management Area Plan for the Rogue Basin (excluding the Bear Creek Watershed) that will be implemented in mid-2000. ODA also regulates Confined Animal Feeding Operations (CAFO), nursery operations, and pesticide use. Oregon Department of Fish and Wildlife ODFW manages and protects fish and wildlife in Oregon. It establishes seasons and tag limits for hunting and fishing activities and provides technical assistance for state regulatory agencies and watershed councils. Oregon Department of Environmental Quality DEQ is responsible for developing water quality standards that protect beneficial uses such as cold-water fisheries, salmonid spawning, drinking water, industrial water supply, recreation and agriculture. The agency also monitors and periodically reviews available Williams Creek Watershed Assessment xvi
data to determine if these standards are being met. This agency manages both point and non-point pollution and implements the provisions of the 1972 Federal Clean Water Act. Oregon Water Resources Department OWRD manages and allocates waters of the state. Local policy was established through the Rogue River Basin Study of 1985. This agency regulates water withdrawal, issues water rights, classifies and regulates stream flow according to beneficial uses, and establishes minimum stream flow levels. OWRD holds certified in-stream water rights in trust for the State of Oregon. Oregon Department of Land Conservation and Development DLCD works with counties, cities, and state agencies to develop and maintain comprehensive land use plans and regulations of Oregon. Division of State Lands DSL operates under the State Lands Board. It administers Oregon’s fill and removal laws and manages the banks and beds of the state’s navigable waterways. This agency issues permits required for any gravel removal within state waterways and regulates impacts to wetlands on all land in the state. Oregon Department of Transportation ODOT is responsible for state and interstate road maintenance and planning. Their jurisdiction in the watershed includes state Route 238 and several bridges. Maintenance and planning activities in sensitive areas are conducted in accordance with the Water Quality and Habitat Guide produced by the agency. Federal Level United States Department of Interior The Bureau of Land Management (BLM) administers 52% of the land in the watershed. This area is managed under the guidelines of the Northwest Forest Plan and is part of the Applegate Adaptive Management Area. A management goal of the Applegate Adaptive Management area is to “achieve healthy, diverse, and functioning ecosystems that are sustainable over time” (Applegate Adaptive Management Area Guide 1998). BLM lands are managed according to the provisions of the Medford District BLM Record of Decision and Resource Management Plan. United States Department of Agriculture The United States Forest Service (USFS) administers 1.5% of the land in the watershed. Approximately 522 acres are managed by the Rogue River National Forest, under the Williams Creek Watershed Assessment xvii
