The Clean Waters Partnership interviewed Ed Rock, Emergency Management Director for Kosciusko County, to learn about flooding in our area and what resources are available to deal with their impact.
How does flooding effect our watershed?
The Upper Tippecanoe Watershed is hallmarked by the abundance of water, including hundreds of lakes, streams, and wetlands.
With the draw of the lakes and the nutrient rich soil, we have built thriving communities, industry, and productive farms. However, the natural topography of the land combined with development designed to fast-track water off surfaces leads to flooding during a large rain event.
What kinds of flooding do we see?
Most river flooding occurs in early spring and is the result of excessive rainfall and/or the combination of rainfall and snowmelt. Severe thunderstorms may cause flooding during the summer or fall but tend to be localized. According to the Kosciusko County Hazard Analysis, the primary source of river flooding is the Tippecanoe River. Although the Eel River in the southwest corner of the county is prone to flooding, it impacts only a small portion of land that is primarily farmland, wetlands, and wildland.
Flash floods, and brief heavy flows in small streams or normally dry creek beds, also occur within the county. Flash flooding is typically characterized by high-velocity water, often carrying large amounts of debris.
Urban flooding involves the overflow of storm drain systems and is also typically the result of inadequate drainage following heavy rainfall or rapid snowmelt.
Who monitors flooding and floodplains?
The Lilly Center for Lakes & Streams also monitors rain events and has live data available for 11 inflows and outlets on Wawasee, Tippecanoe and Winona Lake.
The Department of Natural Resources website contains a wealth of information on floodplains and flooding in Indiana. These floodplain boundaries are decided through a collaboration between FEMA and the National Flood Insurance Program with cooperation from the individual counties. This link contains new DNR Floodplain Information Portal that shows the most recent 100-year floodplain. All you have to do is type in your address to see where your property sits.
Intelligent and well-thought-out development in floodplains is the key to reducing flood-related damages by avoiding interactions with water in the first place.
Does Kosciusko County have a plan for dealing with flooding?
Yes! It is part of the larger Multi-hazard Mitigation Plan to identify natural hazards, corresponding actions and activities to reduce losses, and develop a coordinated process to deal with the threats. Other hazards in this plan include tornado, earthquake, thunderstorm, drought, winter storm, hazardous material, fire, and infectious disease within Kosciusko County.
Summary of Multi-Hazard Mitigation Flood Plan:
What resources are available to residents in our watershed during a flood?
What action can citizens in our watershed take?
The key to manage flooding is to help slow and infiltrate the water. Three easy ways to do that are:
Are there programs offered through the Clean Waters Partnership that help control flooding?
Yes! Many of our cost-share programs will help control flooding. All these practices are designed to slow down water or infiltrate it into the earth. To see if you qualify for cost-share funds contact Brad Clayton.
What else does the Office of Emergency Management wish people knew about flooding?
Avoid flooded roads, for your safety and for the road’s integrity! Imagine what happens when the earth is saturated around and underneath the pavement. The road becomes loose and bendable, and therefore is easily damaged when heavy vehicles cross it. This requires tax-payer funds to repair the damage that could have been avoided.
How can I get information about potential flooding threats and resources?
FEMA: Federal Emergency Management Agency. Their mission is to support the citizens and first responders to promote that as a nation we work together to build, sustain, and improve our capability to prepare for, protect against, respond to, recover from, and mitigate all hazards.
Floodplain: an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
Impervious Surfaces: surfaces that do not allow water to infiltrate the soil
Permeable: having pores or openings to allow liquid to pass through
Stormwater: water on surface in high amounts that accumulates and runs off into a water body
Topography: refers to mountains, valleys, rivers, or craters on the surface
Watershed: An area of land where water flows to a central body of water. A watershed can cover a small or large land area and small watersheds are usually part of larger watersheds. Any activities on that land influence the water quality within that watershed.
