Gully Stabilization Benefits

Water Quality & Conservation Posted on August 18, 2025

On his property along Parker Creek, Jon Filarsky faced a rapidly worsening problem that threatened both his land and the surrounding watershed. Severe gully erosion was cutting deep into the soil, destabilizing the landscape, and carrying tons of sediment downstream. Left unchecked, the damage would only accelerate—prompting Jon to seek out conservation solutions.

Gully Location

About the project

Severe gully erosion was causing significant soil loss—up to 25 feet over five years—on Jon Filarsky’s land, sending sediment downstream into Parker Creek. To address this, a conservation design was prepared, contractor bids obtained, and funding secured for implementation.

The solution

  • Custom-designed rock structures were designed and installed to withstand a 10-year storm event
  • Two rock-lined waterways (75 ft and 47 ft) control water flow and dissipate energy in the swale.
  • Stabilized slopes were seeded with deep-rooted cool-season grasses

The resultsbefore after-01-01

  • Halted ongoing erosion and head cutting
  • Protected valuable land and local waterways
  • Created a healthy, stable landscape for the future
