Hydraulic Mining Dominates the Bay Sediment BudgetPracticed from 1863 – 1884, then outlawed.
>100 million m3 of sediment washed into Central Valley.Main bed sediment pulse passed Sacramento ~1950.
Channel and floodplain deposits remain. still moving thru system.

Level 1: Landscape assessment based on the distribution, abundance, shape, size-frequency, etc of wetlands (e.g., NWI, Ca Wetland Inventory).
Level 2: Rapid assessment using checklists or other semi-quantitative devices to score wetland sites relative to a range of condition from least impacted to highly degraded (e.g. ORAM, CRAM).
Level 3: Evaluation of ecological services in their own regard (e.g., Unit Hydrograph, IBI’s) and to validate Level 1 and Level 2 results
Part of a Developmental Framework for Comprehensive Assessment and
Monitoring

Four attributes of wetland function contribute to the overall wetland condition
Scores are recorded for metrics for these attributes

Score card summarizes the results for sub-metrics, metrics, attributes and the AA.
Scoring is transparent and allows for easy evaluation of AA strengths and weaknesses.
Stressor Checklist can be used to identify possible corrective actions

Steps of CRAM Assessment
Step 1: Identify and classify the Focal WetlandStep 2: Assemble background informationStep 3: Sketch the CRAM Assessment Area (AA)Step 4: Conduct the office assessment of AAStep 5: Conduct the field assessment of AA Step 6: Complete CRAM QA/QCStep 7: Submit assessment results using
eCRAM
