The Galena Territory, Illinois Draft JO DAVIESS COUNTY Multi-Jurisdictional All Hazards Mitigation Plan PARTICIPANTS Apple Canyon Lake Hanover, Village of Apple River, Village of Jo Daviess County East Dubuque, City of Scales Mound, Village of Elizabeth, City of Stockton, Village of Galena, City of Warren, Village of The Galena Territory MARCH 2013 The five year update of this Plan must be completed on or before (date). Jo Daviess County Multi-Jurisdictional All Hazards Mitigation Plan ACKNOWLEDGEMENTS Developing the first All Hazards Mitigation Plan for Jo Daviess County and the participating jurisdictions involved a considerable amount of input from many people. All of these contributions have helped to make this Plan the definitive source of information on hazards, their impacts, and various options to eliminate or reduce these impacts on current and future generations. Information from various government sources has been supplemented by weather data and photographs from personal collections. The Jo Daviess County Multi-Jurisdictional All Hazards Mitigation Planning Committee included residents who live throughout the County. Their knowledge of the devastation caused by severe weather coupled with their commitment to protecting the lives, property, and welfare of Jo Daviess County residents were important ingredients needed to develop this Plan. The Jo Daviess County Local Emergency Planning Committee was active in helping to initiate and sustain the planning process. Ron Data, Chuck Pedersen, and Steve Silberman represented the LEPC throughout the planning process as did other LEPC members including Peg Murphy and Matt Calvert from the Jo Daviess County Public Health Department; long-time Jo Daviess County Emergency Management Director Colin Fulrath; Jo Daviess County Sheriff Kevin Turner; Scott Allshouse of the Northwest Illinois Chapter of the American Red Cross; Susan Coers, IEMA Region 2 Regional Coordinator; Jo Daviess County Highway Engineer Steve Keeffer; and Annette McLane, Jo Daviess County Farm Bureau Manager. Historic photographs emphasize that storm damages are not a recent phenomenon but can be difficult to find. Fortunately an array of historic photographs from the Galena and East Dubuque area were acquired for use in this Plan by Craig Albaugh, Facilities Manager for the City of Galena and Tom Lange, Assistant Chief of the East Dubuque Fire Department and Interim Director of the Jo Daviess County Emergency Management Agency. Historic flood information, news articles, and additional photographs were provided by Madelynn Wilharm of The Galena Territory. Information to assemble this Plan also came from outside the County. Larry Acker and his family have kept the only source of continuous weather records in Northwest Illinois since 1883. Larry’s great grandfather, William Edwin Acker, started keeping records when the Acker Brothers began farming in Polo. Larry lives on this Centennial farm where weather information is supplied to the National Weather Service. Before him, Larry’s mother, Helen Johnston Acker, assisted in keeping weather records. The Acker site is the oldest continuous weather data site in Illinois that has not been moved to a different location. As this Plan is updated, we hope that future generations will continue to build on this document with information and photographs.

  • NATURAL RESOURCES (Updated Excerpt from Jo Daviess Comprehensive Plan Baseline Data)
    ATTACHMENT F: NATURAL RESOURCES (Updated excerpt from Jo Daviess Comprehensive Plan Baseline Data) The natural resources in Jo Daviess County are unique relative to the rest of the state and much of the mid-west because the county is part of the Wisconsin Driftless Region bypassed by continental glaciers of the Ice Age. This region covers parts of southern Minnesota and Wisconsin, Northwestern Illinois and Northeastern Iowa. Glaciated areas were leveled, strewn with glacial debris or "drift" and dotted with lakes and ponds. The driftless areas, on the other hand, have bedrock close to the surface into which deep valleys have been carved by millions of years of weather and erosion. In Jo Daviess County, streams are numerous and the only two lakes are man-made. The relief from the higher ridges to the valley floors is typically 300 feet or more creating a rugged and scenic landscape. Ecosystems can be found in this landscape that are older than those found in glaciated areas. Geology The topography of Jo Daviess County is characterized by rugged relief unique to most of Illinois. Our county, located in the far northwestern corner of the state, is in an area spared by the major glaciations of the last two million years. It is, accordingly, called the "Driftless Area" by geologists, the term "drift" referring to material deposited by glacial activity. The visible landscape that we see today began during the Paleozoic Era (570 to 245 million years ago) when shallow seas repeatedly inundated the interior of the continent. Shells of marine animals, along with muds, silts and sands from eroding highlands, were periodically deposited in those sea bottoms.

Geological Science Field Trips The Educational Extension Unit of the Illinois State Geological Survey (ISGS) conducts four free tours each year to acquaint the public with the rocks, mineral resources, and landscapes of various regions of the state and the geological processes that have led to their origin. Each trip is an all-day excursion through one or more Illinois counties. Frequent stops are made to explore interesting phenomena, explain the processes that shape our environment, discuss principles of earth science, and collect rocks and fossils. People of all ages and interests are welcome. The trips are especially helpful to teachers who prepare earth science units. Grade school students are welcome, but each must be accompanied by a parent or guardian. High school science classes should be supervised by at least one adult for each ten students. A list of guidebooks of earlier field trips for planning class tours and private outings may be obtained by contacting the Educational Extension Unit, Illinois State Geological Survey, Natural Resources Building, 615 East Peabody Drive, Champaign, IL 61820.

  • Driftless Area - Wikipedia Visited 02/19/2020
    2/19/2020 Driftless Area - Wikipedia Visited 02/19/2020 Driftless Area The Driftless Area is a region in southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois, of the American Midwest. The region escaped the flattening effects of glaciation during the last ice age and is consequently characterized by steep, forested ridges, deeply carved river valleys, and karst geology characterized by spring-fed waterfalls and cold-water trout streams. Ecologically, the Driftless Area's flora and fauna are more closely related to those of the Great Lakes region and New England than those of the broader Midwest and central Plains regions. Colloquially, the term includes the incised Paleozoic Plateau of southeastern Minnesota and northeastern Relief map showing primarily the [1] Iowa. The region includes elevations ranging from 603 to Minnesota part of the Driftless Area.

  • What to Do And
    What to See and Do . in Benton Historical Limestone Water Tower Water Street—Benton, Wisconsin Built in 1900, Benton’s historical limestone water tower is one of the few of its type in the Midwest and one of only two in the state of Wisconsin. Originally the water tower had a red wooden tank on top. Perched atop the tank was a windmill that pumped water from the well below and had blades that are said to each have been “as big as a man.” The limestone water tower was Benton’s source of water from 1900 until the spring of 1998 when the current water tower was put into use. In 1999, Benton’s limestone water tower was placed on the National Register of Historic Places. (Image courtesy of Dave Driscoll.) Mazzuchelli Gravesite and Rectory Museum 237 E. Main—Benton, Wisconsin Father Samuel Mazzuchelli came from Italy to America at the age of 22. Following his ordination, he was assigned to be a missionary priest for the Northwest Territory. He was highly admired and earned the respect of all to whom he ministered, including settlers, miners, and the area’s native tribes. Father Mazzuchelli was the child of wealthy parents and received a comprehensive, cultured education which included the command of several languages and the study of architecture. As a pioneer priest, Father Mazzuchelli designed and built 25 churches in the upper Mississippi Valley area—including Benton’s St. Patrick Catholic Church, built in 1852, and New Diggings’ St. Augustine Church, constructed eight years prior to that. (Photos courtesy of Dave Driscoll.) In addition to his renowned missionary work and his formation of Christian communities in the region, Father Mazzuchelli was also a pioneer in Wisconsin education.
