Plan Outcomes

Multidisciplinary technical assessment

• f current watershed conditions,

including:

• Ecological Assessment
• Geomorphic Assessment
• Flood Risk Assessment
• Channel Migration Zone Analysis

Long-Term Vision Watershed Master Plans

Ecological Assessment

Poor Excellent Recommendations: Consider opportunities for improved meanders, habitat, vegetation, etc.; need to create more complexity within the channel No further management recommended

• St. Vrain Creek

Geomorphic Assessment

Long-Term Vision Watershed Master Plans

Left Hand Creek

Good

In tact section of lower Left Hand Creek (on BoCo Open Space). This reach largely in tact due to functioning, connected floodplain.

Poor

Tight bedrock pinch led to stripping of alluvium in James Canyon, ultimately destroying the roadway and the pre-flood channel.
