have the spraying done. Central Nebraska Public Power and Irrigation District is having a <br />• helicopter spray phragmites at the North Platte Diversion Dam. The LCWCA is already <br />contracted with them to do additional work, so they could include aerial spraying of the choke <br />point area in the same project. We would get 28 acres sprayed for $6,000, which is significantly <br />less than the hard engineering solution. This has several beneficial aspects: 1) an opportunity to <br />get spraying accomplished this fall before frost is important; 2) keeps us out of soliciting <br />spraying contractors directly; 3) the LCWCA has its own insurance coverage and will indemnify <br />us; and 4) landowner access agreements are already in place. Kenny said he has coordinated <br />with the LCWCA and the NCF and both are amendable to a simple-form contract and have <br />copies. If there are no objections, we can get the spraying done this week at a low price and have <br />tangible results. <br />Mark Butler asked if it would require just one spray, and if we would have to physically remove <br />the dead material. Kenny said the agreement would accomplish spraying, and that should have a <br />kill time of 3-5 years. Removal is not part of provision, but once dead its ability to impede flow <br />is significantly reduced. Bill Taddicken said eventually, it will be best to find a way to remove it <br />next year because it will stick around. Rowe Sanctuary has worked on spraying this year and it <br />has worked well, so this is a great way to get it done at the choke point. But, in the future, the <br />Program will need to remove the dead phragmites. Keehn said if we can kill the phragmites with <br />spraying, we can then monitor during the pulse flow to see if removal is necessary or if the water <br />passes through well enough. Bleed said it is important to specify in the contract that the <br />contractor will go back and re-spray if it doesn't work right. Kenny said he will talk to the <br />LCWCA to check on this guarantee. Bleed asked if the spraying was just focusing on <br />• phragmites, and Kenny said the spraying will be area-based. Kraus asked if the spraying was <br />being done in lieu of channel cleaning, and Keehn responded that aside from island removal, this <br />is in lieu of channel cleaning. He reported that local residents are not in favor of channel <br />cleaning, so we have gone back to phragmites spraying and island removal. Kenny said it seems <br />we can accomplish flow goals using a much less intrusive approach. <br />Purcell asked if the states need to fund this or if we can also use federal dollars. John Lawson <br />said the legislation seems to be moving along, and this is a small amount of money involved, but <br />the Bureau of Reclamation prefers using state funds until legislation is finalized. Purcell said the <br />project would be done with just state dollars, and Bleed said this is not a problem as long as all <br />the details are worked out. Jeff Runge said the window for spraying is closing fast and the first <br />killing frost will end the spraying time period. Kenny said the helicopter would be departing <br />soon. Bleed asked for details on the window for spraying. Jason Alexander indicated that <br />spraying has to be completed when phragmites "shooters" are growing in July or spraying <br />doesn't work well. Taddicken said Jeffrey Island plots were sprayed in September and <br />phragmites has not grown back. Bleed said we need to address the concern about October <br />spraying and if that doesn't work the contractor must come back to finish the job. <br />Mark Butler asked about the details of the monitoring system. Keehn said it is a visual system at <br />key property locations and that he has cross-sections in the HEC-RAS model that can be used for <br />transects. Rocky reported that he has not yet worked out how we are going to actually record <br />? This document is a draft based on one person's notes of the meering. The official meeting minutes may be different <br />if corrections are made by the Governance Coxnxnittee before approval. Page 4 of 10
