| Headwaters
|
|
Forested, access road, old logging road and cuts, recreation trails, ski runs.
|
| |
|
| |
Provides water source (rainwater and snowmelt) but potential for debris and sediment.
|
| |
|
| Main Stem Flows
|
|
Increased peak flows and frequency due to high percentage of impervious development.
|
| |
|
| |
Bank erosion from hikers and dogs.
|
| |
|
| Storm Water
|
|
Storm drains drain a large urban area, with a high level of impermeable, which causes fluctuating water levels in streams.
|
| |
|
| |
Non-point source water quality problems from urban runoff (especially in Wagg Creek and Lower Mission Creek).
|
| |
|
| Baseflow Maintenance
|
|
Ground water reserves still exist, but some were filled in the past.
Capacity of overall ground water storage reduced by development, due to a high percentage of impervious ground cover, and loss of soil depth. More pronounced in areas of denser development.
|
| |
|
| |
Wetland areas very small.
|
| |
|
| |
Forest limited to ravines and top of bank in mid watershed.
|
| |
|
| Point Source Pollutants
|
|
Small fill site leaching into creek south of CNV Works Yard.
