Summary [1]

The present Knowledge Assessment seeks to answer three sets of questions for each of the ten selected resource topics, from a scientific perspective:

Status and Trend

• What is our present understanding (hypotheses) concerning the status of the condition(s) addressed by the topic? (Note, quantifiable objectives have not been developed for most resource topics, therefore, a lesson learned from the 2017 Knowledge Assessment was that this question may not be appropriate for all resource topics).
• What is our present understanding (hypotheses) concerning the strength and direction of any trend(s) in these conditions?
• How certain or uncertain is this understanding (confidence)?

Drivers and Constraints

• What is our present understanding (hypotheses) concerning the factors (drivers and constraints – see definitions below) that significantly shape the status and trends in these conditions?
• What is our present understanding (hypotheses) concerning the strength and direction of these effects?
• How certain or uncertain is this understanding (confidence)?

Effects of Management Actions

• What is our present understanding (hypotheses) concerning the ways in which each type of GCDAMP management action affects or could affect the status and trends in these conditions?
• What is our present understanding (hypotheses) concerning the strength and direction of these effects?
• How certain or uncertain is this understanding (confidence)?

The last of these three sets of questions may focus on the following actions, identified in the LTEMP FEIS as components of the Selected Alternative and in other agency decision documents (Note, a lesson learned from the 2017 Knowledge Assessment was that not all management actions need to be evaluated every year.):

• Spring HFEs ≤ 45,000 cfs in March or April
• Proactive Spring HFEs ≤ 45,000 cfs in April, May, or June
• Fall HFEs ≤ 45,000 cfs in October or November
• Fall HFEs > 96‐hr duration
• Trout management flows
• Macroinvertebrate production flows
• Humpback chub translocation
• Mechanical removal of rainbow trout from LCR reach
• Mechanical removal of invasive fish species
• Larval humpback chub head-start program
• Riparian vegetation restoration (not assessed for 2019-20)
• Incentivized harvest (new for 2019-20)

Through its answers to the three core questions presented above, the present Knowledge Assessment seeks to:

• Summarize information on status, trends, and the state of knowledge for the nine priority resource topics, from a scientific perspective.
• Summarize expectations about the likely effects of proposed LTEMP management actions.
• Document the state of knowledge of how antecedent conditions, as well as external drivers and constraints, may affect the outcomes of different management actions.
• Identify potential needs for continuing, increasing, reducing, revising, or adding monitoring, research, and other information-gathering efforts to address potentially crucial gaps in knowledge.
