Environmental Conditions Appendix II
Environmental Conditions Environmental Conditions Appendix II The unique geology, hydrology and climates of the Deschutes River Subbasin create a diverse mix of habitat conditions for fish and wildlife. These populations are linked to the ecosystems in which they live and their health, individual characteristics and abundance reflect the diversity ― and quality ― of their environments. Fish populations, for instance, developed complex life histories through time that responded to the subbasin’s considerable variation in habitat conditions. Stream flows, water temperatures, substrate characteristics and other combined attributes affected anadromous fish distribution within the subbasin and timing of migration. Wildlife population abundance and distribution also developed in response to habitat conditions. Native grasslands once covered vast areas and supported species such as sage grouse, which once occurred exclusively in this habitat. Loss of grassland habitat greatly reduced such populations. Today subbasin habitat conditions continue to influence fish and wildlife production, distribution and survival. These habitats and their attributes ― as well as the aquatic and terrestrial populations they support ― are affected by both natural watershed processes and human activities that influence flow, water quality, upland and riparian conditions and instream habitat. This chapter examines how environmental conditions in the Deschutes watershed affect the subbasin’s fish and wildlife populations. Building on the more general review provided in the Overview, the discussion characterizes the environmental conditions within three watershed areas: the Lower Deschutes watershed (below RM 100), Crooked River watershed, and Upper Deschutes watershed (above RM 100). It characterizes the natural watershed environments, such as geology, climate and hydrology, and the focal fish species they support. -
Chapter 5 Supplemental Planning Sections
Chapter 5 Supplemental Sections Planning Section 5.1 Introduction Background This chapter provides material that supplements the other chapters of the Plan. There are no goals or policies in these sections. Purpose The purpose of this chapter is to provide a glossary, list all acknowledged Goal 5 resources in one location (see Section 2.4) and list all Goal Exceptions and Goal 5 inventories. The final section in this Chapter is a table to track all amendments to this Plan. This table will ensure a clear legislative history is maintained. The following information is covered in this chapter. Glossary and Acronyms (Section 5.2) . Goal 5 Water Resources (Section 5.3) . Goal 5 Wildlife Resources (Section 5.4) . Goal 5 Open Space and Scenic Views and Sites Resources (Section 5.5) . Goal 5 Energy Resources (Section 5.6) . Goal 5 Wilderness, Natural Areas and Recreation Trails (Section 5.7) . Goal 5 Surface Mining Resources (Section 5.8) . Goal 5 Cultural and Historic Resources (Section 5.9) . Goal Exception Statements (Section 5.10) . Goal 5 Adopted Ordinances (Section 5.11) . Ordinance History (Section 5.12) 2 DESCHUTES COUNTY COMPREHENSIVE PLAN - 2011 CHAPTER 5 SUPPLEMENTAL SECTIONS SECTION 5.1 INTRODUCTION Section 5.2 Glossary and Acronyms Glossary Note: Terms defined in Deschutes County Code 18.04 (Zoning Code) are not repeated here, but have the same meaning as DCC 18.04. “Agricultural-tourism” or “Agri-tourism” means a commercial enterprise at a working farm or ranch, operated in conjunction with the primary farm or ranch use, conducted for the enjoyment and/or education of visitors, that promotes successful agriculture, generates supplemental income for the owner and complies with Oregon Statute and Rule. -
Upper Deschutes River Fish Managementplan
Upper Deschutes River Fish ManagementPlan Draft May22, 1996 Oregon Department of Fish and Wtldlife Oregon Department of Fish & Wildlife Page 1 of 431 Upper Deschutes River Basin Fish Management Plan 1996 COMPLETED DISTRICT DRAFT 04/11/96 6:12:58 PM DESCHUTES RIVER from Wickiup Dam to Bend (North Canal Dam) including the tributaries Fall River and Spring River Overview This portion of the basin plan includes the Deschutes River from Wickiup Dam (RM 227) downstream to Bend (North Canal Dam, RM 164.8), Fall River, and Spring River. The Little Deschutes River, a major tributary which enters at RM 193, is not included because of its' length and connection with other waters in the basin. The Little Deschutes River will be presented in a separate section of the basin plan. In the Habitat and Fish Management sections of the following discussion, the Deschutes River will be divided into two sections; Wickiup Dam to Benham Falls (RM 181), and Benham Falls to Bend (North Canal Dam). The reason for this is based on stream morphology and changes in fish populations. Benham Falls is a high gradient natural cascade which separates the Deschutes River into two logical sections with low gradient above the falls and high gradient below. Similarly, fish population composition changes at Benham Falls with brown trout dominant above and rainbow trout dominant below. The remaining sections; location and ownership, fish stocking history, angling regulations, management issues, summary of alternatives and alternatives will be presented as (1) Deschutes River, and (2) Tributaries. In 1987, the Oregon legislature designated the section of Deschutes River from Wickiup Dam to General Patch Bridge, and from Harper Bridge to the north boundary of the Deschutes National Forest as a State Scenic Waterway. -
