Robinson Lake Eco-oasis Billboard

Robinson Lake: Northwest Indiana’s Next Eco-Oasis

Just off I-65, minutes from the interstate but worlds away from the noise, sits quiet little Robinson Lake — 28 acres of water surrounded by woods, wetlands, and Erin’s Farm, the amazing animal rescue next door. For years it’s been a hidden fishing hole that slowly filled with silt and farm runoff. Most drivers zooming past on the highway never even know it’s there. But that could change — in the best possible way. A community-driven restoration could turn Robinson Lake into a sparkling, eco-oasis that proves beauty, community, and cleanup can go hand-in-hand. Routine travelers will be able to visibly watch the transformation from cute, local park, to a flourishing food forest eco-oasis, and sharing resources between the farm and the park is a win-win for all.

What is possible (2026–2029)

  • Crystal-clear water you can see ten feet down again

    • Gentle late-summer drawdown + natural bio-dredging (the same recipe that’s worked on hundreds of local lakes, described in Big Maple Lake Plan)

    • A sweeping roadside forebay and riprap treatment zone would be perfectly aligned along I-65 to catch the highway and farm runoff to strip out oil, salt, and nutrients, spilling clean water into the lake or ditch systems

  • A spectacular floating island oasis right in the middle

    • Built Aztec Chinampa or other floating style, clean fill discussed earlier, and thousands of water-cleaning plants plus edible oyster and king stropharia mushrooms - paddle boarders get the best view

    • Visible from I-65 — drivers will literally watch the lake heal in real time as the island grows greener every month

    • Free mushroom harvesting for visitors

    • Permaculture food forest helps to provide food for local residents, wildlife, and guests

      • Creating root-cause solutions to address food shortage and hunger in our local community

Glass-crushing & filtration system

  • Recycled glass from visitors & northwest Indiana bars and restaurants can be crushed on-site and used as ultra-effective, sparkling filter media in the riprap zones and shoreline berms for architecture & disaster avoidance

  • Turns glass “waste” into permanent, beautiful, toxin-grabbing armor that keeps runoff clean

  • Glass-cleaning process can use solar pumps for lake water, cleaning both glass and water, filtering water through a photo-ready garden of beautiful plants & mushrooms

  • Simple, welcoming public access

  • Small canoe/kayak launch possible

  • Woodchipped paths wind through the beautiful food forest

    • Safe and gorgeous - solar rope lighting winds through plants and arches; Up-lighting faced into trees

    • Picnic areas connected by short looping trail that’s perfect for evening walks or relaxed horse rides

Nothing huge. Nothing overbuilt. Just a clean, healthy, insanely photogenic lake you can see from the highway that quietly proves we can heal water, create habitat, and turn trash into treasure — all at the same time.

Robinson Lake won’t just be restored.
It could be the postcard win that makes people pull off I-65 and say, “Wait… we can do THIS with our lakes!?”

How to make it happen…

CHRISTINE PIERCE – Disaster Avoidance

This analysis evaluates transforming Robinson Lake (17-acre urban park lake in west Hobart) into a self-sustaining "Eco-Oasis" using non-permanent Mycoremediation enhancements (mycelium filtration rafts, solar pumps, glass sand aggregates from local crushing, native plantings, and possibly sluice grates for fish/wildlife flow). It leverages free/ low-cost resources (blighted yard waste, student labor) to cut maintenance, boost revenue, and generate grants—proving we can begin to off-set the costs to run the city without the threat of the data center. All figures in 2025 USD; based on DNR/EPA benchmarks, scaled from Lake George pilots.  Plan can be accomplished either via city or local adjacent property owners/neighborhood.

Project Overview

  • Scope: Deploy 10–15 modular myco-rafts (30 m² each) for nutrient filtration (60–80% phosphorus/nitrogen removal); add 2–4 solar pumps ($5k total) for circulation; possible to crush/install 500 tons glass sand for shoreline stabilization; plant natives (vetiver, cattails - permaculture expert, landscape architect & disaster avoidance team select plants for beauty & function); create removable sluice grates if desired. No construction—enhances existing 30-acre park.

  • Timeline: Phase 1 (2026): $120–150k, 6 months; full ROI in 3–5 years.

  • Why Now?: Builds on DNR's 2012 fish management agreement; qualifies for untapped LARE/EQIP grants (e.g., $24k+ for similar shoreline work in LaGrange County).

Net Present Value (NPV) Snapshot

  • Assuming 5% discount rate over 10 years: $1.2–$2.1 million positive NPV.

    • (Breakeven Year 2 (Let’s plan for 3); cumulative benefits exceed costs by Year 4 (plan 5.)

 Recommendation

Suggest Approving Phase 1 (grant apps - LARE/EQIP deadlines Q1 2026) for $35–50k net investment.

This eco-boost turns Robinson Lake from a $60–100k annual cost into a revenue engine—realigning the in-coming tax obstacles organically, no data center needed. Let's make Hobart's west side the envy of NW Indiana, advertising like a free, giant billboard from I-65.
