City of Eagle Lake Drainage Study

Eagle Lake, MN | Water

Overveiw

ISG worked with the City of Eagle Lake and local landowners to provide cost-effective options and prioritization recommendations to reduce flooding from the surrounding rural and urban landscape.

Opportunity

The City of Eagle Lake is part of a complex watershed composed of rural and urban landowners. Flooding in a small creek through the City routinely caused damage to houses, public infrastructure, and the City of Eagle Lake sports complex.

Solution

Pairing leading edge software with ISG’s water resources professionals, the City of Eagle Lake and landowners were provided with a comprehensive stormwater model and drainage analysis to accommodate dynamic stakeholder needs and develop a long-range strategy to reduce flooding.

An industry leader in stormwater modeling, ISG designed an extensive XPSWMM model for the City and surrounding watersheds to address stormwater management planning goals on 1,000 acres of rural and 500 acres of urban land. Protecting the resources of private landowners and public lands, the $30,0000 comprehensive drainage study provided overland flow visualization for large storm events and floods. Pipe capacity evaluations were conducted and opportunities for stormwater retention were identified to allow water quality improvements and flow attenuation. The drainage study, which focused on ways to reduce urban flooding throughout the City, offered multiple prioritized alternatives, cost estimates for each option, and sequencing recommendations allowing the City to serve its constituents and plan for the future.

Key Points
  • Flood control phased plan
  • 1,000 acres rural + 500 acres urban
  • $30,000 project
  • XPSWMM model
  • Collaboration with landowners and the City
