LANE COUNTY OREGON MULTI-JURISDICTION HAZARD MITIGATION PLAN Page | 46
3. RISK ASSESSMENT 44 CFR Requirement §201.6(c) (2) [The plan shall include] A risk assessment that provides the factual basis for activities proposed in the strategy to reduce losses from identified hazards. Local risk assessments must provide sufficient information to enable the jurisdiction to identify and prioritize appropriate mitigation actions to reduce losses from identified hazards The purpose of risk assessment is to identify and describe hazards that affect Lane County and analyze potential losses for human life and material assets. Through better understanding of potential hazards and the degree of risk they pose, more successful mitigation strategies can be developed and implemented. This risk assessment follows the four-step process described in the FEMA publication 386-2, Understanding Your Risks: Identifying Hazards and Estimating Losses, listed as follows: Step 1: Identify Hazards Step 2: Profile Hazard Events Step 3: Inventory Assets Step 4: Estimate Losses This section is organized into three subsections that address the four steps of the risk assessment process. 3.1 Identifying Hazards. This subsection addresses Step 1 and lists the hazards considered during the planning process and those ultimately profiled in the plan. It also describes methods, definitions and data sources used for the hazard identification and profile process. 3.2 Hazard Profile. This subsection addresses Step 2 and presents a detailed outline for each identified hazard. Each hazard profile is addressed as a plan subsection and includes a general description, affected geographic area, and discussion of previous occurrences, probability of future occurrence, magnitude and severity and an assessment of overall vulnerability to each hazard. -

On Reconciling Lake Classification with the Evolution of Four Oligotrophic Lakes in Oregon
AN ABSTRACT OF THE THESIS OF DOUGLAS WILLIAM LARSON for the DOCTOR OF PHILOSOPHY (Name) (Degree) inFISHERIES presented on 7)_ (Major) (Date)1 Title: ON RECONCILING LAKE CLASSIFICATION WITH THE EVOLU- TION OF FOUR OLIOT Abstract approved: Redacted for privacy A John R. Donaldson Limnological data were collected from studies of four Oregon lakes that are classified as oligotrophic--Crater, Odell, Waldo, and Woahink.Phytoplankton primary production was estimated periodi- cally using a standard carbon-14 in situ method. Bioassay experi- ments were conducted to determine whether water samples, treated with various kinds and concentrations of inorganic nutrients, might stimulate carbon uptake by phytoplankton.Chlorophyll a measure- ments complemented production estimates made with carbon-14. In comparing the lakes, differences were noted concerning lake origin, watershed features, basin morphometry, surface elevation, optical and thermal properties, and water chemistry. More notable, however, was the significant difference in phytoplankton primary production and biomass among the four lakes.During July and August, 1969, productivity averaged 253. 1 (Crater), 1533. 2 (Odell), 35.5 (Waldo), and 301. 1 (Woahink)mgC/m2dar.For the same period, concentrations of chlorophyll a averaged 34. 4 (Crater), 99. 03 (Odell), 4. 7 (Waldo), and 24. 7 (Woahink)mg/rn2.This resulted from the dif- ferent uses each lake received.It is suggested that, on the basis of productivity, lakes are unique environments and are evolving at dif- ferent rates in response to natural and artificial (cultural use) enrich- ment. The need for an adaptable classification system that would take into account the continuous process of lake evolution was emphasized. -

Chemical Control of Elodea Densa Planch. and Other Submersed Aquatic Plants As Influenced by Several Environmental Factors
AN ABSTRACT OF THE THESIS OF JOHN WILLIAM MACKENZIE for the DOCTOR OF PHILOSOPHY (Name) (Degree) in FARM CROPS presented on 5-j/q70 (Major) (Date-) Title: CHEMICAL CONTROL OF ELODEA DENSA PLANCH. AND OTHER SUBMERSED AQUATIC PLANTS AS INFLUENCED BY SEVERAL ENVIRONMENTAL FACTORS Abstract approved: Redacted for Privacy W. R. Furtick Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyri- [do1,2-a:2',11-c]pyrazinediium dibromide), alone and in combina- tion with disodium endothall (disodium salt of 7-oxabicyclo[2.2.1] heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate. Studies were conducted in coastal lakes of Oregon infested with E. densa.Dichlobenil (2, 6 dichlorobenzonitrile) was applied following diquat treatments in an attempt to extend length of the control period. Plant samples were collected from trials in Siltcoos Lake for diquat analysis.Laboratory studies were conducted to determine the effects of water temperature, exposure time, light quality, and time of appli- cation on the activity of diquat and diquat combinations against E. densa.Weights of stem, length of stem, and visual control evalua- tions were used to measure effectiveness of herbicide application. In field trials, effective seasonal control of E. densa was achieved by application of 0.25 ppmw diquat.Addition of 0.25 ppmw endothall or 0.5 ppmw copper sulfate pentahydrate did not enhance the activity of the 0.25 ppmw rate of diquat.The optimum elodea control from 1.0 ppmw diquat did not prevent extensive regrowth the following season.Dichlobenil at 10 and 20 pounds active per acre suppressed but did not completely prevent regrowth in previously diquat-treated plots.Levels of diquat in treated plants were not increased by addi- tion of endothall or copper sulfate.The influence of water movement in Siltcoos Lake from wind and flood water resulted in drift of chemi- cal from treated areas and consequent control of exposed E. -

Final Introduced Fish Report
OREGON PLAN for SALMON and WATERSHEDS COASTAL COHO ASSESSMENT INTRODUCED FISHES IMPACTS (PECE Policy Format) Oregon Department of Fish and Wildlife Mike Gray May 6, 2005 Part 4(C) ODFW (4) Exotics Final Report May 6, 2005 PECE (Policy for Evaluation of Conservation Efforts) Policy Certainty that the conservation effort will be implemented. 1. Describe the staffing, funding level, funding source, and other resources necessary (and available) to implement the conservation effort or regulatory program. Monitoring and management of introduced fishes are currently accomplished primarily through ODFW Fish District staff, and their activities funded through the agency’s base budget. Funding of District management activities is typically through Other Funds (License and Tag fees) and Federal matching funds (Sport Fish Restoration, e.g.). While there is no current Western Oregon Warmwater Fish Biologist position within ODFW, the Eastern Oregon Warmwater Biologist has provided coastal Districts with assistance through population modeling, project review, and technical advice/expertise. 2. Describe the legal authority to implement and the commitment to proceed with the conservation effort or regulatory program. ODFW has the legal authority granted to the agency by State statute for management of fish and wildlife populations, namely the Wildlife Policy—ORS 496.012. This includes a policy and commitment to “…prevent the serious depletion of any indigenous species…”, which would apply to management of introduced fish species and their impacts on coho salmon. 3. Describe the legal procedural requirements (e.g. environmental review), if any exist, necessary to implement the effort or regulatory program. Management objectives and actions for some populations of introduced fish are established through Basin Fish Management Plans, adopted by the Oregon Fish and Wildlife Commission. -
Chapter 3: Aquatic Resources
CHAPTER 3: AQUATIC RESOURCES HISTORIC CONDITIONS Upland Sediment and Wood Routing The processesthat affect stream function are related to channel gradient and confinement by the surrounding hill slopes. Streams have been separated into geomorphic segments (Appendix G) to explain how water, wood and substrates move through the watershed (Mup 4. Ingeneral, source reaches provide material, transport reaches move material through, and deposition reachesrepresent areas where material is deposited. Identifying the location of geomorphic segments are in the watershed allows resource managers to predict where potential fish habitat is and where restoration efforts will be most successful. This Coastal Lakes Analysis Area contains an unusually high amount (you meanases? percent?)of unconfined deposition area. Theseparticular areasare unique becausethey contain long, very broad valley bottoms above coastallakes with a high percentageof wetlands just above the arms of these lakes. These conditions create exceptionally good coho rearing habitat. The long deposition reachesin the upland valleys include Maple, Fiddle, Fivemile and Leitel Creeks and sorneof their larger tributaries. Th"y composea seriesof valleys above the coastal lakes that have historic4lly contained a wide diversity of habitats. Before human settlement, these long, low gradient valleys contained streams that meandered back and forth between steep adjacent hillslopes. fust above the lake arnrs and well up into these valleys, there was probably an abundance of side ehannels and wetlands associated with these streams. Riparian vegetation consisted of alternating patches of sedges, shrubs and trees, producing shady conditions along a majority of these stream lengths. Up higher in these valleys there were probably stream sections dominated by alder and conifer, and also meandering streams with side channels. -

ISSN 0458-7227 TSILTCOOS LAKE POST OFFICES by David A. Ramstead Tsiltcoos is an Indian name which has been shortened to Siltcoos by the uS. Board of Geographic names. Siltcoos Lake in Douglas and Lane Counties is a fresh body of water covering several square miles. Siltcoos River,several miles in length, connects it with the Pacific Ocean. Tsiltcoos is said to be the name of a local Indian chief or an Indian family name. Another version is that it means "plenty elk". Tsiltcoos Lake was originally called Ten Mile Lake by the early settlers.
