Take a Tour

Watershed Signage

Signage installed at Griggs, O'Shaughnessy & Hoover Reservoirs invites park visitors to  take a self-guided tour along the shoreline & learn about the green infrastructure installed there.

Rain gardens, porous pavement & more can improve the quality of storm water entering the reservoirs that supply our drinking water.

Native Plants

Trees and VegetationProviding a deep-rooted vegetative buffer around reservoirs provides many environmental benefits, including better water quality.

Please see the lists below for plants to use in Land Stewardship Plans at each reservoir. All proposed plantings must be approved by the Watershed Management Section prior to planting on city-owned property.

The Purple Coneflower (Echinacea purpurea) pictured is just one native plant that is in common to all three reservoirs. A beautiful addition to the landscape, it thrives in our climate, spreads and requires little to no maintenance.
