4. Information from watershed district re aquatic invasive species boat inspections Supervisors: Louise Smallidge ▫ Bob Rosenquist ▫ Diane Blake ▫ John Rheinberger ▫ Jim Levitt MEMORANDUM TO: CMSCWD Board of Managers FROM: Matt Downing, Washington Conservation District DATE: 11/20/2017 RE: Countywide Watercraft Inspection Program Thank you for your support of the 2017 AIS Watercraft Inspection Program. Because of your commitment to the resources of your watershed, those of the county and state an additional 144 hours of inspections were performed that otherwise would not have. In CMSCWD alone, 1,769 watercraft inspections were performed. Through the inspection process, boaters were educated on how to better protect the lakes that they are using, and steps were taken each time to ensure that invasive species were not introduced into each lake at the time of that launch/transported away from the lake. Attached you will find the summary of the 2017 season that was prepared for Washington County. Please contact me if you have any questions about this or any other aspect of watercraft inspections. I look forward to working with you in the future on prevention and management of invasive species. Supervisors: Louise Smallidge ▫ Bob Rosenquist ▫ Diane Blake ▫ Jo hn Rheinberger ▫ Jim Levitt AIS Inspection Summary Points 2017 The WCD supervised 6 DNR authorized Watercraft Inspectors for the 2017 season with funding from Washington County, Carnelian Marine St. Croix Watershed District (CMSCWD) and Valley Branch Watershed District (VBWD). These inspectors were present at 13 county water access locations starting May 6th through October 18th. During the inspection season 2,020 hours of inspections occurred, resulting in 3,042 inspections occurring during this time period. Compared to 2016, roughly 200 hours less of inspections occurred, but 200 more actual inspections were performed. The reduction in hours performed was due to constraints with staffing and weather concerns, funding was only slightly less in 2017 than in 2016. The number of inspections performed in 2017 was very comparable to 2016. Entering versus exiting inspections were distributed similar to 2016 results, and were still in line with the statewide average of 60/40 towards entering. Conducting more evening inspections may move this closer to a 50/50 distribution. While steps were taken in 2017 to encourage this approach with some success, further modifications to the program are planned in the future to achieve more exiting inspections. While there has been more of an emphasis statewide lately on entering inspections to prevent new infestations, the high proportion of already infested waters in close proximity or within Washington County makes exiting inspections just as important. Supervisors: Louise Smallidge ▫ Bob Rosenquist ▫ Diane Blake ▫ Jo hn Rheinberger ▫ Jim Levitt The number of total drain plug violations observed in 2017 dropped again from the prior year, both in actual number and as a percentage. On incoming inspections the rate of violation has dropped each year of the program from 9% (2015) to 7% (2016) to 5% (2017). After three years of data collection it does appear that this is a trend, and indicates that increased inspections and education are having a positive impact on the behaviors of boaters in Washington County. While these data are encouraging, efforts should continue to get results in Washington County closer to the statewide average of 4%, or perhaps better than that average. Of the violations where the last lake the watercraft was in was reported, 18% of them had come from water infested with Zebra Mussels, Spiny Water Flea or Eurasian Water Milfoil. 20% of those violations listed Big Marine as the last lake visited; greater effort should be made to increase both the number of inspections and education of the users of that lake to reduce the likelihood of spread of AIS from that source. Supervisors: Louise Smallidge ▫ Bob Rosenquist ▫ Diane Blake ▫ Jo hn Rheinberger ▫ Jim Levitt Of the 1,730 incoming inspections performed in 2017, 71 AIS violations were observed. This is a rather drastic increase from 2016, the cause of which is not immediately apparent. However, the variability in the people performing the inspections each year could play into this, as well as improved training occurring in 2017 versus prior years. 60 of the 2017 violations were plants attached to the boat or trailer attempting to launch, and were successfully removed by hand and did not enter the lake in question. The remaining 11 violations were water present in the watercraft; all of which were directed to completely drain before launch was allowed. These results are slightly lower than the statewide trend for violation. Supervisors: Louise Smallidge ▫ Bob Rosenquist ▫ Diane Blake ▫ Jo hn Rheinberger ▫ Jim Levitt Every access scheduled had inspections performed, except for Oneka due to staffing issues once waterfowl hunting started. Lakes in the CMSCWD received the highest proportion of inspection hours, followed by those in the VBWD. This was both because of additional funding provided by those organizations as well as dictated by use. Big Marine was the most inspected lake in 2017 as in years prior. Big Carnelian was the second highest, and would have likely had even more inspections if the landing had not been closed in September for repairs. Average number of inspections per hour of staffing also shows that CMSCWD and VBWD lakes tend to be the highest use landings in the county. Please note, although this summary addresses trends and data for Washington County lakes it references only those that are serviced by the Washington Conservation District. All the lakes located in CLFLWD have inspections performed by CLFLWD or Chisago County staff. Also, the MNDNR performs inspections on many of the high use landings in the county, as well as being primarily responsible for the access points on the Saint Croix River.
