What you can do to keep the lake healthy.
Shoreline living means owning, renting, or caring for property along Hayden Lake and the streams that feed it. Because water moves downhill, what happens on shoreline property reaches the lake faster and more directly than anywhere else in the watershed. This page explains what that responsibility involves: how to care for the bank, which projects require a permit, how to landscape and plant for a lake setting, and the seasonal maintenance that protects water quality.
Why Shoreline Property Matters
Rain and snowmelt carry whatever they pass over — soil, fertilizer, pet waste, oil from driveways — toward the lowest point. On shoreline property, that trip is short, and there is little ground left to filter it.
Phosphorus is the nutrient of greatest concern. It occurs naturally, but added amounts act as fertilizer in the water, feeding algae growth that reduces clarity. Keeping nutrients out of the lake is far easier than removing them later.
