Following the presentations and discussions with the audience and breakout groups, the panelists and the workshop committee worked through a brainstorming session to develop their recommendations and discuss such related topics as attributes of flow dynamics, empirical analysis vs. process modeling, non-linearity of biological responses to habitat size, and origin of and current scenarios involving Adaptive Environmental Management.
The panelís specific recommendations are as follows:
2. The river system is unique in that it is unregulated and is a bedrock-controlled system. The nature of the low flow challenge precludes the use of standard hydraulic and biological modeling approaches.
3. Existing biological data and understanding are inadequate to support a specific, quantitative environmental flow-by.
4. Based on the three preceding observations, the approach recommended is an adaptive strategy with the following elements:
b. Collect background (hydrologic, biologic) data to provide inputs to the development of a biological community-habitat conceptual model.
c. Develop the conceptual model for identifying:
ii. information gaps, and
iii. testable hypotheses about the effects of hydrology on the biological community.
e. Forecast physical/chemical/biotic responses, (e.g., to drought conditions)
f. Evaluate and refine management targets
