Notice of Availability, and Request for Comments within 30-days, Monitoring Plan and Quality Assurance Plan for TMDL Compliance in Lake Elsinore,Canyon Lake, and the San Jacinto Watershed.

In 2012, at the request of the stakeholders, the Regional Board reduced the in-lake and watershed discharge monitoring so that the money could be spent on nutrient control measures, like the alum addition to Canyon Lake and the aeration/mixing system installed in Lake Elsinore.  The proposed Monitoring Plan has been modified to reflect current conditions and the past monitoring data.

The watershed stakeholders have submitted a revised monitoring program plan and QAPP (see link above).  Regional Board staff has reviewed the proposed revised monitoring program plan and QAPP and is soliciting comments from the public.  The link below is to the August 1, 2016 Final QAPP, with the Monitoring Plan included in Appendix C.   Please provide any comments, by September 19, 2016, to Mark Smythe at mark.smythe@waterboards.ca.gov or Ken Theisen at ken.theisen@waterboards.ca.gov.  Please call Ken Theisen at (951)320-2028 if there are any questions related to this matter.
