Eagan watershed group seeks local input as 10-year plan is updated

The Eagan–Inver Grove Heights Watershed Management Organization asked the Sustainable Eagan Advisory Commission on April 8 to help shape its updated 10-year watershed management plan and sought priorities from commissioners on lakeshore management, salt use, irrigation and homeowner actions.

The request came during a presentation by Victoria Bridal, board administrator for the Eagan–Inver Grove Heights WMO, who said the update is part of the statutory 10-year process and that staff want “those involved citizens to get some input on how we develop the plan.”

Bridal told the commission that the WMO focuses largely on education and voluntary projects because most on-the-ground stormwater work in the political watershed is carried out by the City of Eagan under its MS4 permit from the Minnesota Pollution Control Agency. “The city is now doing a lot of that footwork,” she said, noting the WMO’s role in funding outreach and incentive programs such as landscaping-for-clean-water grants, rain-garden installations and a “lawns reimagined” pilot that substitutes lower‑maintenance, drought‑tolerant turf for traditional lawns.

Commissioners identified local problems they want the WMO to prioritize. Thomas Lake’s summer algae blooms and general lake greening were raised, along with drought and more extreme precipitation patterns. Several commissioners emphasized shoreline quality and the need to reduce foot‑traffic damage and poor lakeshore landscaping. “Helping people to make good choices about how and when they fish and whether it’s safe to eat that,” one commissioner said when discussing fish consumption and recreation.

Bridal said three Eagan lakes have fish‑tissue advisories for mercury and that the city maintains a neighborhood fishing guide that lists advisories and access points. She also discussed wastewater and groundwater connections: Eagan’s municipal drinking water and most local irrigation are sourced from groundwater and household plumbing ultimately sends wastewater to the Seneca wastewater treatment plant operated by the Metropolitan Council. Bridal noted some salt and water‑softener discharge eventually reach wastewater treatment and that the plant does not treat for chlorides.

Commissioners suggested specific WMO approaches: expand education on winter salt application and low‑salt contracts for commercial winter maintenance contractors; offer incentives or training to calibrate household water softeners to reduce chloride loads; promote adopt‑a‑drain or storm‑drain outreach programs; and target outreach to lakeshore owners for native plantings and shoreline buffers. Bridal described previous incentive models used with farmers in Dakota County and said similar payments or training could be considered for commercial and residential landowners.

Bridal said the WMO’s previous plan listed seven water bodies as impaired for nutrients, and that the City of Eagan has made progress: nutrient impairments were “either delisted or in the process of being delisted.” She encouraged commissioners to submit additional feedback and said the WMO will provide a draft plan to the public for comment later in the process.

The presentation also included background on why the WMO exists. Bridal cited Minnesota Statute 103B as the statutory basis for metro watershed organizations and explained that political watershed boundaries allow municipalities to coordinate even when hydrology does not follow political lines. She noted Eagan’s watershed largely overlaps the city boundary, a feature that simplifies some coordination compared with multi‑city WMOs.

Bridal left contact information and invited commissioners to review the WMO’s draft when it is released and to forward written suggestions to staff.
