PRRIP — ED OFFICE DRAFT 10/02/2008 <br />45 with the field work, may lead to some shuffling of how projects rank. Boyle is also updating the <br />46 loss model to Grand Island. The study is on schedule with a draft report expected mid October. <br />47 There was a discussion about implications of any schedule creep and potential to affect the <br />'48 ability to move forward with projects for 2011 (primarily pulse flow related) and 2014 (species <br />49 and annual pulse flow related which was referred to in meeting discussion as "target flow" <br />50 related) Program goals. The pulse flow and reduction to shortages to target flow objectives are <br />'51 not mutually exclusive. Pulse flow is important for testing the Adaptive Management Plan <br />52 (AMP), so that is why it was intentionally placed at the front -end of Program document. <br />53 <br />54 Choke Point — The National Weather Service provided a letter in early September, raising the <br />55 flood stage to 6.0 feet and lowering the flow to 1,600 cfs. This is a reflection, at least in part, of <br />56 phragmites. Phragmites that were sprayed last October (28 acres) will be mechanically removed <br />'57 this fall, October/November, along with channel work to move sand. The ED office has <br />58 assembled a list of contractors and is coordinating with any land owners who could be impacted. <br />59 <br />60 Water Quality Study —The contractor has been working with the ED Office and the Water <br />61 Quality Focus Group to identify a plan (specific locations, frequency, and constituents) and how <br />62 to utilize other current data collection efforts to gain information. The contractor is working on a <br />' 63 draft budget, recognizing the need to not turn this into a research effort but to focus on <br />64 constituents that have been identified as impacting target species. A draft budget will be <br />'65 provided next week; the project is on schedule. <br />66 <br />67 Stage Change — This is an AMP project, to identify if management actions in the central Platte or <br />'68 flow - related activities could impact pallid sturgeon in the lower Platte. The contractor needs a <br />69 high flow event for data collection but this summer had too high of flows. Additional sampling <br />70 events will be conducted this fall and then construction of a comprehensive 1 -D model and 2 -D <br />71 model of smaller areas. Completion anticipated at end of 2009. <br />72 <br />73 Stream Gage Installation — Two new gages for Lexington and Shelton have been ordered; the <br />'74 Program is paying for the gages, shelters, some DNR staff time to install and develop rating <br />75 curves, and some on -going funding for DNR to include in their network. Plan for installation <br />76 this fall (stage only) and ready for monitoring the pulse flow in the spring. Water quality <br />'77 parameter probes will also be added in the spring. We will be working with DNR so that the <br />78 Program's website displays real -time gage data. Tom Hayden sends a daily spreadsheet <br />79 summarizing flows. <br />80 <br />81 Vegetation /Geomorphology Protocol — This is an AMP project. The RFP was issued and should <br />82 have a contractor selected this fall with draft protocol available for implementation by spring <br />'83 2009. The protocol will not likely be peer- reviewed by then, but will adjust based on peer <br />84 review. <br />85 <br />'86 Water Evaluation Process <br />87 A process is needed to evaluate water supplies that the Program is investigating; this was initially <br />88 identified as a need in evaluating Tract 0811. The GC asked the WAC to develop a procedure <br />t <br />Page 2 of 5 <br />1 <br />
