The Montana Department of Environmental Quality (DEQ) is ensuring that assessments are completed for all public water systems in Montana. The purpose of these reports is to provide information so that the public water system operator, consumers, and community citizens can begin developing strategies to protect your source of drinking water. The information that is provided includes the identification of the area most critical to maintaining safe drinking water, i.e., the Inventory Region, an inventory of potential sources of contamination within this area, and an assessment of the relative threat that these potential sources pose to the water system.

    DRAFT 2 Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources; they are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components.

    Appendix 4 Brief Geologic History of the Flathead Subbasin

    Appendix 4 Brief Geologic History of the Flathead Subbasin The Precambrian rocks of the Belt Supergroup that underlie the Flathead Subbasin formed from sediments deposited in and near a large but shallow sea or inland lake during the middle Proterozoic (from roughly 1,600 to 800 million years ago). This large body of water, which may have been similar to today’s Caspian Sea, occupied parts of present-day eastern Washington, the panhandle of Idaho, western Montana, and adjacent areas of Canada. Over a period of 800 million years, more than 18,000 feet of sediment accumulated from surrounding highlands. The ever-increasing load depressed the sea floor, and variations in the downwarping, combined with changes in the amount and type of sediment flowing into the basin, resulted in alternate layers of different kinds of sediment, including sand, silt, and limey mud. As the great mass of sediment accumulated, moderate heat and pressure associated with deep burial caused mild metamorphism, converting the rocks to quartzite, siltite, argillite, recrystallized limestone, and dolomite. The rocks, however, retained much of their sedimentary character; features such as ripple marks, mud cracks, salt casts, and fossil algal stromatolites are well preserved. In some areas, igneous rocks were injected into the sedimentary rocks and formed sills that today parallel the layering in the rocks. Approximately 150 million years ago the North American plate began colliding with numerous large island arcs in the Pacific. The impacts created and elevated mountain chains, forming the ancestral Rocky Mountains. Immense compressive forces persisted for some 90 million years and were enough to produce mountains several hundred miles inland from the edge of the continent.

LaFave Larry N. Smith Thomas W. Patton *The atlas is published in two parts: Part A contains a descriptive overview of the study area, along with water-quality data and an illustrated glossary to introduce and explain many specialized terms used in the text; Part B contains the 11 maps referenced in this document. The maps offer expanded discussions about many aspects of the hydrogeology of the Flathead Lake area. Parts A and B are published separately and each map in Part B is also available individually. iv Ground-Water Assessment Atlas 2 Front Cover: Flathead Lake and the valley to the north are featured in this north–northeast-looking, low-oblique photograph. Formed by glacial damming of the Flathead River during the last ice age, Flathead Lake is 30 miles long and 12 to 14 miles wide. The small city of Kalispell is barely discernible north–northwest of the lake. Kal- ispell is a center for tourism, trade, and the production of livestock, grain, fruit, timber, and aluminum. The Flathead River drains into Flathead Lake, forming a conspicuous delta in the northeast part of the lake. South- west of Kalispell are the small Foy Lakes; Whitefish Lake is to the north. Near the top center of the photograph are Glacier National Park and Lake McDonald. Image courtesy of Earth Science and Image Analysis Laboratory, NASA Johnson Space Center (http://eol.jsc.nasa.gov).

  • Draft Environmental Assessment North Shore Wildlife Management

    Draft Environmental Assessment North Shore Wildlife Management

    Draft Environmental Assessment North Shore Wildlife Management Area Proposed Addition November 2015 Executive Summary North Shore Wildlife Management Area Proposed Addition Draft Environmental Assessment Montana Fish, Wildlife & Parks (FWP) proposes to purchase approximately 76.7 acres of farmland and wetlands located along the north shore of Flathead Lake about 4.5 miles east of the community of Somers. Funding for the project would be provided by the Pittman-Robertson Wildlife Restoration Act. The primary purpose of the proposed land acquisition is to protect and manage this land to restore or improve natural riparian/wetland habitats, to continue annual crop production to benefit resident and migratory waterfowl, to improve and maintain habitat for other wildlife, and to provide opportunities for seasonal and compatible public recreation. Other benefits of this project include protecting ground water, surface water, and wetlands on or near Flathead Lake, which will help improve or maintain the high water quality of Flathead Lake for benefits of aquatic life and fish and wildlife habitat. FWP proposes to incorporate this parcel into FWP’s wildlife management area program and it would become part of the existing North Shore Wildlife Management Area (North Shore WMA). The proposed Management Plan is included as part of the draft environmental assessment (EA). This property borders to the west the 189-acre North Shore Wildlife Management Area that FWP acquired in 2013 which is adjacent to the 160-acre North Shore State Park/Wildlife Management Area that FWP acquired in 2008. It also borders to the east the access road to the U.S. Fish & Wildlife Service Flathead Lake Waterfowl Production Area.

Photo courtesy gravityshots.com ii Voices of Our Lake Photo courtesy gravityshots.com founded the Whitefish Lake Institute (WLI) in 2005 to give Whitefish Lake a voice. Its muted waters were undergoing increasing pressure and it needed I better understanding. After all, the lake provides a beautiful backdrop to our community while being a major economic driver. WLI’s role is to define the underpinnings of this lake-based ecosystem and to develop methods we can employ to manage and care for it. Through the years, WLI and project partnershave amassed a solid baseline awareness of the water quality and food web that shape the lake and local streams. In 2015, we compiled that information in one narrative—the Whitefish Area Water Resources Report: A Status of the Whitefish Lake Watershed and Surrounding area. This report and all its supporting re- sources are available at www.whitefishlake.org. Photo courtesy Whitefish Lake Institute In the report, the lake’s voice becomes clearer, revealing a unique record of trends and patterns – the result of natural forces and human actions that operate at time scales ranging from minutes to decades.
