If you live on Delavan Lake, you want a landscape that protects your view, your shoreline, and the lake you love. At the same time, you need to stay within local rules and choose plants and materials that can handle wind, wakes, and Wisconsin winters. The good news: you can create a beautiful, low‑maintenance shoreline that is lake‑safe and property‑smart.
This guide walks you through practical design moves, native plant options, erosion‑smart hardscapes, and a simple process to get it done in Delavan. You’ll learn what to check before you start, how to keep your view while adding protection, and where to find local help. Let’s dive in.
What “lake‑safe” means in Delavan
Lake‑safe landscaping protects Delavan Lake while improving your shoreline’s stability and beauty. Local stewardship involves the City of Delavan or your township, Walworth County Land Use & Resource Management, the Delavan Lake Protection & Rehabilitation District, the Wisconsin Department of Natural Resources (WDNR), and UW‑Madison Extension programs. Each plays a role in water quality, erosion control, and invasive species management.
Wisconsin’s shoreland zoning framework (NR115) shapes what you can do near the water. Local governments implement it through their own ordinances, so requirements can vary by municipality and parcel. Vegetation removal, setbacks, impervious surfaces, and shoreline stabilization are common areas of regulation. In‑water work or stabilization measures often need WDNR review. Planting native vegetation is typically allowed, while placing rock or fill usually triggers permits or specific standards.
Who to call first
Before you grade, rock, or plant in the water, check these in order:
- City of Delavan or your local zoning office (to confirm local shoreland rules)
- Walworth County Land Use & Resource Management or Land Conservation (site guidance and local programs)
- Wisconsin DNR (permit guidance for shoreline stabilization and in‑water work)
- Delavan Lake Protection & Rehabilitation District (local stewardship info and potential cost‑share opportunities)
Regulations exist to protect water quality, prevent erosion, and conserve habitat. Getting clarity upfront helps you design smarter and avoid delays.
Design principles that work on Delavan Lake
Shoreline designs that succeed on Delavan balance four goals: reduce runoff and nutrients, stabilize soils, support habitat, and maintain your view and access. The following moves are proven and practical.
Choose your buffer width
A vegetated buffer is the single best investment you can make for water quality and bank stability. Wider is better, but even a smaller edge helps. Consider these common tiers and verify local rules for your lot:
- 10 to 15 feet: A functional edge that slows water, filters sediment, and reduces splash erosion.
- 25 to 35 feet: A strong water‑quality and habitat buffer that balances lake views and protection.
- 50 feet or more: A full restoration zone that maximizes pollutant interception and slope stability.
A well‑planned buffer reduces mowing, keeps geese pressure down, and creates a natural, high‑end look that fits a Delavan setting.
Layer your planting for strength and beauty
A resilient buffer uses vertical layers so roots hold soil at different depths and foliage intercepts rainfall.
- Canopy trees, used sparingly, add long‑term structure and shade. Place them upslope or interspersed so they do not block surface‑level plantings from capturing runoff.
- Understory trees and shrubs form the backbone of stability and screening.
- Herbaceous plants, especially native sedges and grasses, knit the soil together at the water’s edge.
- Emergent plants at the toe of the bank can help dissipate wave energy where depth and rules allow.
This layered approach looks natural and keeps maintenance manageable once established.
Keep views with a narrow corridor
You do not have to choose between a buffer and your lake view. Create a narrow, sinuous view or access corridor that preserves sightlines while keeping most vegetation intact.
- Width: 3 to 4 feet for a footpath, up to 6 feet for ADA or cart access.
- Placement: Route it along the gentlest grade and avoid the steepest sections.
- Surface: Permeable materials like mulch, crushed stone, spaced stepping stones, or wood chips perform well. For wet patches, short boardwalks are effective.
- Upkeep: Maintain edges so the corridor stays defined without expanding over time.
This approach gives you comfortable access without creating a runoff chute to the lake.
Mind the lawn and manage stormwater
Continuous turf to the waterline is the least protective option. If you love lawn, keep it upslope and let a native buffer intercept runoff at the edge. For roofs and patios, redirect downspouts into vegetated areas or rain gardens. Infiltration trenches, shallow swales, and cisterns or rain barrels can reduce peak flows and nutrient delivery.
Native plants that love Delavan shores
Choose species native to southeastern Wisconsin that match your moisture conditions: drier upperslope, mesic mid‑slope, and wet toe or shallow water. Favor deep‑rooted plants for bank stability and source locally when you can.
- Trees and small trees (use sparingly near the edge): River birch (Betula nigra), Red maple (Acer rubrum), Eastern red cedar (Juniperus virginiana) where appropriate, and Black willow (Salix nigra) for wetter pockets.
- Shrubs and understory: Red‑osier dogwood (Cornus sericea), Ninebark (Physocarpus opulifolius), Buttonbush (Cephalanthus occidentalis) for wet edges, Serviceberry (Amelanchier arborea), and Elderberry (Sambucus canadensis).
- Sedges and grasses: Tussock sedge (Carex stricta), Lake sedge (Carex lacustris), Pennsylvania sedge (Carex pensylvanica) upslope, and Little bluestem (Schizachyrium scoparium) for drier sites.
- Perennials and wildflowers: Blue flag iris (Iris versicolor) at the shallow edge, Swamp milkweed (Asclepias incarnata), Cardinal flower (Lobelia cardinalis) for moist toes, Pickerelweed (Pontederia cordata) for emergent planting, and Joe‑Pye weed (Eutrochium purpureum) upslope.
- Groundcovers: Wild strawberry (Fragaria virginiana) and Pennsylvania sedge offer low, tidy coverage without choking out wildflowers.
Note: Planting emergent or submerged vegetation in the water can be regulated. Coordinate with the lake district and WDNR before planting below the ordinary high water mark.
Simple templates to copy
Pick the approach that fits your lot size, slope, and goals.
- Minimal native edge (10 to 15 feet): A sedge‑dominant strip with low shrubs for stability, plus a 3‑foot mowed or mulched corridor to the water. Keep most of the buffer undisturbed.
- Balanced buffer (25 to 35 feet): Scattered canopy trees, a strong mid‑zone of shrubs, and a sedge and meadow band at the edge. Build a 3 to 6‑foot curving path. Add a small rain garden upslope to catch roof runoff.
- Full restoration (40 feet+): Multi‑tiered buffer from trees to emergents. Where appropriate, a coir log or a thin rock toe protects the base while plants establish. Keep lawn only above the buffer for entertaining.
Erosion‑smart hardscapes and living shorelines
Choose stabilization that matches your site’s wave energy, slope, soils, and exposure to boat wakes. Softer, bioengineered options often perform well while preserving habitat.
When rock makes sense
For higher‑energy shorelines, layered rock (riprap) can dissipate wave energy and protect the bank. It is durable but can be costly, may require engineering, and typically needs permits. A thinner rock toe paired with a vegetated slope above is a good compromise that stabilizes the base without turning the whole shore into stone.
Seawalls and bulkheads provide a rigid barrier, but they reflect wave energy and can worsen erosion on neighboring properties. Consider these only as a last resort, and expect permitting and habitat tradeoffs.
Softer options for calmer stretches
On low to moderate energy sites, coir logs and brush mattresses protect the toe while native plants root in. A living shoreline uses emergent plantings and low structural elements to absorb wave energy and trap sediment. These approaches look natural and support fish and bird habitat, especially on gently sloping shores.
Terraces, steps, and seating that soak in rain
Create usable spaces that do not shed water straight to the lake. Permeable pavers, crushed stone patios, and spaced stepping stones reduce runoff. Terraced boulder steps hold slopes in place and can include planting pockets for color and habitat. Add swales, French drains, or infiltration trenches to redirect roof and driveway flows into planted areas.
A practical game plan
Tackle your shoreline project in clear, manageable steps.
Step 1: Assess the site
Walk the shoreline after a rain to see how water moves. Note slope, soil type, sun and wind exposure, boat‑wake impacts, and any areas of active erosion. Map existing vegetation, docks, and paths so you can work with what is already stable and native.
Step 2: Coordinate permits and expectations
Contact your city or township zoning office, Walworth County Land Use & Resource Management, and the WDNR before you plan any grading, rock placement, or in‑water planting. Loop in the Delavan Lake Protection & Rehabilitation District for local guidance and potential programs. Early coordination will shape a design that meets local rules and your goals.
Step 3: Design, plant selection, and sourcing
Choose a buffer width that fits your lot, sketch a narrow view corridor, and place plant layers to match moisture zones. Favor deep‑rooted sedges, shrubs, and native perennials. Source regionally grown stock for better establishment. For larger or engineered projects, consult a shoreline professional with freshwater experience.
Step 4: Install with erosion control
During installation, use silt fence or wattles to keep soil on site. Plant at correct depth, mulch appropriately, and water consistently while roots establish. If you install rock toes, coir logs, or terraces, follow manufacturer or engineer guidance and secure any required permits.
Step 5: Care for years 1 to 3
Expect the first seasons to be about watering, weeding, and replacing a few plants. Mow or trim only the designated corridor and paths. Watch for invasive species and coordinate with the lake district or WDNR if you spot problem plants. Avoid major disturbance during nesting season, and leave some woody debris upslope for habitat when practical.
Costs, funding, and local help
Project costs vary based on plant size, linear feet of shoreline, and whether you need engineered rock or terracing. Many small planting projects can be DIY at modest cost, while larger stabilization jobs are an investment. Ask the Delavan Lake Protection & Rehabilitation District and Walworth County conservation staff about potential cost‑share programs or referrals. In some years, funding flows through county or state programs that support shoreline restorations.

FAQs
What is a good shoreline buffer width for Delavan Lake?
- A 25 to 35‑foot buffer is a strong balance of water‑quality protection and views. Even a 10 to 15‑foot native edge helps, and 50 feet or more maximizes habitat and filtration. Always confirm local rules for your parcel.
Do I need a permit to place rock or build a seawall on Delavan Lake?
- Many stabilization measures, including riprap and seawalls, require WDNR review or must follow specific standards. Check with your city or township, Walworth County, and the WDNR before any grading or in‑water work.
Which native plants are best for a sunny shoreline in Walworth County?
- Mix deep‑rooted sedges and grasses with shrubs and moisture‑loving perennials. Tussock sedge, lake sedge, red‑osier dogwood, buttonbush, blue flag iris, and swamp milkweed perform well when matched to the right zone.
How can I keep my lake view and still add a buffer?
- Create a narrow, curving view corridor, typically 3 to 4 feet wide, with permeable materials. Keep the rest of the buffer intact and plant lower‑growing species in key sightlines.
What is a living shoreline, and will it work on Delavan?
- A living shoreline combines native emergent plants with low structural elements like coir logs to absorb wave energy. It works best on gentle slopes and lower‑energy stretches; higher‑energy sites may need rock toes or engineered solutions.
How should I manage lawn near the waterline?
- Keep lawn upslope and let a native buffer intercept runoff at the edge. Direct downspouts into vegetated areas or rain gardens instead of toward the lake to reduce nutrient loading.
