1. (a) Any surface water monitoring required pursuant to Env-Wq 403.26(c) shall be conducted in accordance with (b) through (d), below.

2. (b) The monitoring shall include an initial survey that incorporates the following:

   1. (1) An initial inventory and mapping of aquatic flora and fauna species and habitat;
   2. (2) Identification of the factors that control the elevation of water levels; and
   3. (3) A general description of anticipated seasonal fluctuations in temperature profiles and nutrient balances.

3. (c) Long-term monitoring of surface waters shall include:

   1. (1) Monitoring of water levels in lakes or ponds at a frequency that is adequate to assess the potential occurrence of impacts to these water bodies as a result of the withdrawal;
   2. (2) Measurement of changes in stream flow along a representative section of each water course, or stream reach, that might be influenced by the withdrawal, at a frequency that is adequate to assess the potential occurrence of impacts to the water resource as a result of the withdrawal, using methods that are accurate and technically defensible; and
   3. (3) Monitoring of instream or other submerged habitat to identify the health of aquatic ecosystems.
4. (d) When surface water monitoring includes water level monitoring, the monitoring point locations and reference point elevations shall be established in accordance with Env-Wq 403.30.
