Lamar Watershed USGS No. 1107-0207-060-004

Tuesday, December 10, 2006, a group met at the Wolf Center University of Missouri Extension Center, for preliminary discussions regarding formation of a Lamar (MO) Watershed District. Representatives from the Missouri Rural Water Association (MRWA), Missouri Department of Natural Resources (MDNR), Environmental Protection Agency (EPA), USDA's Natural Resource Conservation Service (NRCS), City of Lamar and and the University of Missouri Extension (MU) discussed issues, including Wellhead Protection and Source Water Protection Plans, Total Maximum Daily Limit (TMDL) and identifying a Community Planning Team, to formulate the plan.

Wellhead Protection Plan
5-Steps to Developing a Wellhead Protection Plan
1. Form a Community Planning team
2. Delineate the Wellhead Protection Area
3. Identify and locate potential sources for contamination
4. Manage Wellhead Protection Area (regulatory and non-regulatory)
5. Plan for the future (contingency plans, identy future problems and solutiuons)
(Wellhead Protection: A Guide to Small Communities, EPA625/R-93/002)

Sourcewater Protection Plan
1. Delineate te Source water Assessment Plan
2. Conduct an inventory of potential contamination sources
3. Determine susceptibility of water supply for contamination
4. Release the assessment to the public

Define Water Quality Criteria
3-Types of Standards
1. Numeric (maximum concentrations and minimum/maximum acceptable levels)
2. Narrative (desirable biological conditions and "Free From" standards)
3. Antidegradation values

Developing a Total Maximum Daily Load (TMDL)
1. Identify more data
2. Identify possible sources
3. Use data to model the stream
4. Calculate how much pollutant the stream can handle
5. Divide load among sources
6. Develop Plan

Comments made during the meeting:
1. TMDL's are a tool, not a weapon.
2. It is the right thing to do (restoring water quality using the watershed approach)
3. "A stream is a reflection of its watershed."
4. Nutients do not have standards.
5. Modeling will determine the target TMDL.
6. "If you are part of the problem, you must be part of the solution."
7. Agencies do not have all of the answers.
8. "If we don't start, we will never get there."

Watershed Management Plan
9-Critical Elements
1. Identify causes and sources/groups of similar sources of contamination
2. Estimate expected load reductions
3. Description of Non-Point Source management measures
4. Estimate of financial andtechnical assistance needed
5. Information/education to enhance understanding and encourage participation
6. Implementation schedule
7. Description of measurable milestones
8. Determine whether loading reductions are achieved
9. Plan monitoring, evaluation, revision.
