Griswold & Caves Creek Subwatershed Streambank Stabilization

In 2012, the Great Lakes Commission awarded CRWP a Great Lakes Basin Program for Erosion and Sediment Control Grant to reduce sediment in the Griswold and Caves Creek subwatersheds (HUC 041100030402). Griswold Creek starts in Chester Township, flows through Russell Township, and enters the Chagrin River in Hunting Valley. Caves Creek starts in Chester Township, flows through Kirtland, and enters the Chagrin River in Willoughby Hills.  Both Griswold and Caves are coldwater habitat streams that harbor sensitive fish species.  These streams maintain cold temperatures because they are mostly fed by groundwater.  Griswold Creek's bed and banks are severely eroding, causing excessive sediment inputs to the State Scenic Chagrin River and ultimately Lake Erie. 
 
Between 2012 and September 2015, CRWP worked with three interested landowners to stabilize 2,489 linear feet of streambanks in these subwatersheds through the cost-share assistance program.  Streambank stabilization projects occurred along Griswold Creek in Russell Township and along headwater streams of Caves Creek that flow through Geauga Park District’s Orchard Hills Park.  Planting woody vegetation along eroding streambanks is the most cost-effective method of streambank stabilization and was used most frequently in this project.  Live stakes, or cuttings from plants such as dogwoods and willows, can be planted in the dormant season (November to April) directly into eroding streambanks.  Larger specimens in containers can add to the variety of species and can be planted during the growing season.
