Louisville Water Restrictions 2026

Voluntary Drought Watch in Louisville: target 2–3 days/week and avoid 10am–6pm watering, voluntary effort now reduces the risk of mandatory Stage 1.

Set mower height to 3–3.5 inches, taller cool-season grass develops deeper roots and tolerates drought far better than short-cut turf.

Use cycle-and-soak (e.g. 5 min run, 30 min rest, repeat) on Colorado clay soils to prevent runoff to gutters and driveways.

Overseed thin areas with a drought-tolerant fescue blend in early fall, cuts long-term water demand by 30–40% versus pure Kentucky Bluegrass.

Apply 2–3 inches of wood chip mulch around trees and shrubs, reduces soil temperature and retains moisture in Colorado's arid climate.

Skip summer fertilising, nitrogen forces growth that demands more water during peak heat.

Audit your sprinkler system for overspray onto sidewalks and driveways; broken or misaligned heads are the single biggest cause of water waste.

Convert ornamental turf to xeriscape using Blue Grama, Buffalo Grass, or native Colorado plants, eligible for utility rebates in many districts.

Hand watering with a shut-off nozzle is unrestricted at all stages, prioritise mature trees and high-value shrubs over turf.

Monitor louisvilleco.gov weekly. If snowpack and streamflow do not improve, Stage 1 mandatory restrictions (with assigned days and fines) become likely.
