MIG 2 Water Quality and Quantity

Study GoalsStudy Goals

Prepare an adequate baseline of water quality information for Lake Martin and the Project tailrace.

Develop a Plan to evaluate any proposed Project operation changes identified during relicensing.

Study MethodologyStudy Methodology If review of the project operations and downstream flood analyses

identifies a potential increase to the winter rule curve or change to the amount of time the summer rule curve is in effect at Lake Martin, the implementation of that change and any potential impacts to water quality of the project will need to be analyzed.

Continuation of Baseline Water Quality Sampling APC will continue their collection of water quality sampling on the

lake and tailrace to be used in development of the 401 water quality certification application.

Analysis of Nutrient Levels in Lake Martin Nutrient levels in the lake may need to be addressed in relation to

lake classifications. If so, APC will examine nutrient inputs into the lake in relation to observed lake productivity. This will be developed with ADEM and with the MIG 2 as deemed necessary.

Revisions to Study MethodologyRevisions to Study Methodology APC will continue to collect water quality

sampling on the lake and tailrace to be used in development of the 401 water quality certification application.

If necessary, nutrient levels in the lake may be reviewed in relation to lake classification.

Study GoalStudy Goal

Develop a list of all NPDES permits on Lake Martin and identify their location and pollutant load.

Study MethodologyStudy MethodologyData Collection Techniques Existing information will be used to facilitate data collection for this

study. First, a request for up to date NPDES data from the ADEM will be made.

Once a list of NPDES permit locations is complete and other existing literature has been complied and reviewed, a draft report will be issued to Martin Issue Group (MIG) 2 for their review and comment. The report will include a list of the NPDES locations, owners, and effluent limits. Comments received from MIG2 will be incorporated into a final report.

Data Analysis Other than a literature review, there will be no data analysis

associated with this study. The GIS overlays may be compared with areas of Lake Martin experiencing water quality problems to better understand the impacts of discharges.

Study GoalsStudy Goals

Identify “hot spot” erosion areas on the lake or tailrace.

Investigate some tributaries for “headcutting”.

Identify areas that currently have or could potentially have nuisance aquatic vegetation.

Revisions to StudyRevisions to Study MethodologyMethodology Tributary headcutting will be investigated

on at least two of the larger tributaries of the lake.

Sedimentation areas will be identified with LIDAR and photography information on the lake.

Some verification through field observations.

Surveys for nuisance aquatic vegetation.
