Flood Risk: The Village of Tiskilwa has a “Guarded” risk of flooding. Type(s) of Flooding: Riverine Flooding/ Ice Jams Area of Risk: Property on northeast side of village along Big Bureau Creek is at risk of flooding. This area has been identified as a 100-year floodplain by the village’s FEMA Flood Insurance Rate Map (FIRM). A levee system was constructed in 1974 to protect this area from a one (1) percent annual flood, also known as a 100-year flood. Approximately 45 homes are protected by the levy. The levy is not certified to receive accreditation from FEMA. The village has four (4) watershed dams that prevent flooding throughout the town. The dams were constructed in 1960 to prevent frequent flooding. The earthen dams are in good condition, but the village can no longer control the valves on three (3) of the four (4) dams because of siltation. Dredging and repairs are needed to prevent future flooding. Ice jams on Rocky Run Creek have caused damage to the village’s bridges. The village does not have frequent problems with surface water issues or basement backups.

Community Risk Assessment events in Bureau County since 1965. Although snow accumulation may vary, weather events typically cover a large area. Data for individual communities was not reported. Extreme Temperatures Risk: Extreme heat and cold can have detrimental effects on the human body including illness and death. Exposure to extreme heat can lead to heat rash, exhaustion, and stroke. When exposed to extremely cold temperatures, the human body loses heat quickly. Unable to replace utilized energy, the body is susceptible to hypothermia and frostbite. Extreme heat and cold can be problematic for public water systems. Although water main breaks are thought to occur more frequently during the winter, they can happen anytime of the year. According to AccuWeather.com, prolonged hot and cold temperatures cause the ground to shift more abruptly, which leads to water main breaks. The age and condition of water mains can also play a factor. The Village of Tiskilwa has an “Elevated” risk of experiencing extreme temperatures. Dangerous Winds Risk: This category includes thunderstorm winds, high winds, and strong winds. Bureau County is at a “Severe” risk of having dangerous winds that can lead to property damage and crop damage. During high winds, people are at a greater risk for injury and death as a result of flying debris such as trees and power lines. Bureau County reported 159 dangerous wind events since 1965 that caused approximately $2.5 million in property and crop damage. Town officials report that straight-line winds have impacted the village in the past. The Village of Tiskilwa has an “Elevated” risk of dangerous winds. Lightning Risk: Lightning is caused by the buildup and release of atmospheric electricity. Whenever there is a thunderstorm, lightning has occurred. Lightning can strike anywhere and has the potential to cause fatalities, injury, and property damage. When lightning strikes, it impacts a small area. The Village of Tiskilwa has a “Guarded” risk of experiencing damages as a result of lightning. Drought Risk: Drought is caused by a lack of precipitation over an extended period of time. A prolonged drought can have a devastating impact on a region’s economy and quality of life.
