ii Hydrology Design Report, Swan River Detailed Floodplain Study May 2015 1.0 INTRODUCTION As part of the Missoula County Memorandum of Understanding (MOU) (Reference 9) Agreement activities, DNRC is assisting Missoula County to complete a new detailed riverine floodplain study, with floodway, for a section of the Swan River beginning at the Lake/Missoula County boundary and extending approximately 19.1 miles upstream near the Beaver Creek confluence. Per the MOU, DNRC has completed a new hydrologic analysis to be utilized for the new study. The study reach is currently mapped by FEMA using approximate methods. This study will be completed satisfying current state and FEMA standards for Detailed/Enhanced floodplain studies. A Flood Insurance Study (FIS) has been completed for Missoula County and Incorporated Areas dated August 16, 1988; however, an update to the FIS has been completed and is slated to become effective on July 6, 2015. A summary of the Digital Flood Insurance Rate Map (DFIRM) panels covering this study reach is presented below (Reference 2): Community Community No. FIRM Panels Effective Date Missoula County, MT 300048 30063C0200D 30063C0075D 08/16/1988 30063C0050D 30063C0200E 30063C0075E 07/06/2015 30063C0050E This report summarizes the hydrologic analysis and results for the new detailed study stream reach described. The new study includes hydrologic analysis to estimate the 10-, 4-, 2-, 1-, and 0.2 percent-annual-chance flood discharges for the Swan River. 1.1 LiDAR Collection In 2012, Missoula County contracted with Watershed Sciences, Inc. to collect Light Detection And Ranging (LiDAR) data for four areas of interest for the purpose of supporting floodplain mapping projects: 1. Rock Creek floodplain, 2. Bitterroot River floodplain, 3. Swan River floodplain, and 4. Clearwater River floodplain. Accuracy of the topographic data meets FEMA standards for detailed level floodplain mapping. The LiDAR data covers the project reach for this study. 1.2 Watershed Description The Swan River originates from Gray Wolf Lake in the Mission Mountain Range and flows generally in a northwesterly direction before emptying into Flathead Lake at the town of Bigfork. 1 Hydrology Design Report, Swan River Detailed Floodplain Study May 2015 At its mouth, the river drains a watershed area of approximately 723 square miles. The Swan River valley bottom was formed by glacial melt waters and reworked by fluvial processes. The valley is bounded on the east by the Swan Mountain Range and on the west by the Mission Range. The vegetation in the valley is dominated by subalpine firs with slopes ranging from 0 to 20 percent. 1.3 Effective FIS (Flood Insurance Study) Hydrology The effective floodplain mapping for the Swan River in Missoula County stretches from the Lake County boundary upstream to the Beaver Creek confluence, which matches the extents of the study at hand. The level of detail of the effective mapping is approximate, as it has been carried forward from the historic flood hazard boundary maps (FHBMs) developed in the 1970s. In Flathead and Lake Counties, the Swan River floodplain has both approximate level and detailed level mapping; information about the effective detailed studies is shown in Table 1.

Table 1 is a summary of the effective detailed level studies on the Swan River. There are also several reaches of the channel with approximate level mapping which are remnants of the FHBMs from the 1970s. Each of the effective detailed studies included a hydrologic analysis including estimation of peak flows. The following is a description of the hydrologic analysis method selected for estimating peak flows for each study: Lower Swan River Study – A Log-Pearson Type III analysis was performed on the annual maximum discharges to determine peak return flows (Reference 4).

Box 201800 · 1515 East Sixth Avenue · Helena, MT 59620-1800 · 406-444-3009 This document should be cited as follows: Greenlee, J.T. 1998. Ecologically significant wetlands in the Flathead, Stillwater, and Swan River valleys. Unpub- lished report to the Montana Department of Environmental Quality. Montana Natural Heritage Program, Helena, MT. 192 pp. The Montana Natural Heritage Program received a wetland protection Abstract grant from the Environmental Protection Agency to identify and inven- tory ecologically significant wetlands and prioritize them for conserva- tion, restoration, and mitigation applications. Much of the state lacks basic information about its wetland resources like National Wetland Inventory maps, and there is even less information available about which of the remaining wetlands are functionally intact and of high quality. This report summarizes the results of a field inventory of high quality wetlands in the Flathead Valley. The project focused on both public and private wetlands found in the Flathead Lake, Stillwater, and Swan drainages in the Flathead River watershed. We identified potential wetlands for inventory by querying locally knowledgeable individuals, and by using National Wetland Inventory maps, aerial imagery, and agency data. Criteria used to select wetlands for inventory included large size, wetlands without geomorphic or hydrologic modification, presence of intact native plant communities, presence of concentrations of rare plants or animals, and intact uplands.

Estimating Wetland Condition Locally: An Intensification Study in the Blackfoot and Swan River Watersheds. Report to the U.S. Environmental Protection Agency. Montana Natural Heritage Program, Helena, Montana. 52 pp. plus appendices. ii EXECUTIVE SUMMARY This report summarizes the results of our fourth statewide rotating basin assessment, focusing on wetlands in the Blackfoot and Swan subbasins of western Montana. We assessed wetland condition within nine watersheds at multiple spatial scales. We conducted Level 1 GIS analyses that produced: 1) wetland landscape profiles, which summarize information on wetland abundance, type, and extent within a given watershed; and 2) a landscape characterization, which characterizes the anthropogenic stressors such as roads and land uses, as well as general information regarding wetland landscape context, using readily available digital datasets. We carried out Level 2 assessments to provide rapid, field-based assessments of wetland condition based on four attributes: 1) Landscape Context; 2) Vegetation; 3) Physicochemical; and 4) Hydrology.

FLATHEAD LIVING Fall 2004 www.flatheadliving.com 79 At the main lodge you enter another gate– KOOTENAI LODGE this one small and inviting, like one you would expect in a secret garden. You im- mediately feel safe and quieted in the court- yard that leads to the grand main lodge. Whimsical etchings created by Charlie Russell in a bygone era are lit up by bright afternoon sun – salamander, turtle and a noble Indian headdress. You are tempted to take off your shoes so that you can feel the curve and dip of the salamander and the warm cement on your feet. You swing the heavy double door open and the latch clinks with the thud of the door behind you. Twirling to take in the im- mense room, warmed by the red-hued larch logs and accented by the soft grey of un- peeled cedar, you imagine the delicious sound of music and laughter in this party place. You turn in a circle, slowly now, to take in the scope of this huge room: the walk- in fireplace, antique wicker furniture, a dozen animal mounts, and a Steinway grand piano.

Pecora, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 STUDIES RELATED TO WILDERNESS PRIMITIVE AREAS Pursuant to the Wilderness Act (Public Law 88-577, Sept. 3,1964) and the Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines are making mineral surveys of wilderness and primitive areas. Areas officially designated as "wilder­ ness," "wild," and "canoe" when the act was passed were incorporated into the National Wilderness Preservation System. Areas classed as "primitive" were not included in the Wilderness System, but the act provided that each primitive area should be studied for its suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. This bulletin reports the results of a mineral survey in the Mission Mountains Primitive Area, Montana. The area discussed in the report corresponds to the area under con­ sideration for wilderness status. This bulletin is one of a series of similar reports on primitive areas.
