1. The board approved the Minutes of April 16, 2008 posted at www.GarrisonLake.org
Old Business
a. OPRD Garrison Lake Outlet Project update - Frank Eckley explained how the lake level is naturally dropping, so the outlet flow is expected to stop soon. “Everything is working as planned”, per Eckley. He said that the outlet held the lake level at a winter maximum of 16.8′, with a gradual decline from the outflow (as per design). Eckley agreed that the dunes are building back up. There was a discussion about the recent OPRD purchase and development of Arizona Beach RV Park.
b. Garrison Lake “Facts Sheet” - The board had no corrections, but did suggest improving the format to more reader friendly. (It will be posted to the website).
New Business
a. City water activities update - Mike Murphy stated that the treated water loss is at approximately 50% on average. He explained how leak detection is ongoing with immediate repairs performed when leaks are located. Murphy clarified that broken pipe repair does not add pressure and cause additional leaks within the adjoining pipes, contrary to local suspicions.
b. Port Orford Watershed Council update - John Leuthe recapped how he stepped down from the Council chairmanship after 9 years, and Steve Taylor is now the chairman. Leuthe said the Wetlands are an ongoing Council project and they keep abreast of land development that can impact the watershed. Leuthe mentioned that there is a Cedar Terrace development, preparing for 31 homes. He shared his concerns about land clearing and the invasive plants that frequently take over the disturbed soil. Leuthe shared photos of several sites that have been overcome by broom and other invasive weeds. Leuthe is pursuing some form of stewardship regulations to manage these invasive plant issues. Discussion followed on weed abatement with a consensus that there are no county or city regulations. Leuthe intends to address the P.O. Planning Commission. Murphy suggested a county ordinance may be the tool to pursue. Leuthe also brought up possible usage of Garrison Lake for fish rearing. Myers and Mazur pointed to the decision to stabilize the lake, with minimizing salinity, as being the turning point away from its use for rearing anadromous fish. (Anadromous fish move from saltwater to spawn in freshwater, examples: Coho Salmon, Steelhead Trout).
c. ODF&W programs update - Steve Mazur, Assistant Fish Biologist, spoke about fish stocking and sampling of Garrison Lake. Mazur stated that every year since 2002 the ODF&W have been sampling Garrison Lake. He said that over the last five years, less salt water intrusion has eliminated the herring population and there are now more Cutthroat trout. The Cutthroat includes large females and many in the 10″-12″ range. Mazur said ODF&W have stopped stocking Steelhead. Mazur said Rainbow Trout are now stocked, and 8.000 small Rainbows were added in the fall of 2007, followed by catchable size stocked in the spring of 2008. ODF&W have found Steelhead using the outlet to enter the lake. Mazur explained that rearing conditions are very good in the lake, but large populations of anadromous fish are unlikely to develop. He said that the Rainbows will probably not spawn, but some Cutthroat may spawn up the creeks feeding Garrison Lake. He stated that ODF&W do not currently track spawning. Mazur said that 600 Large Mouth Bass were stocked in 2007, with many being found in the samplings that have followed. Nowlin asked about the environmental requirements for the fish, and Mazur said that ODF&W are very pleased with the improvement of the water and insects of Garrison Lake. Mazur mentioned that Cutthroat do eat small fry (supplemented by excess from the hatchery), plus the insects. He said that historically Bass have been in the lake and they are top level predators, eating bull frogs and other fish. McQuade asked about weeds impacting the sport fishing and ODF&W sampling. Mazur said he was not aware of any problems. The board agreed that the weed problem gets more intense in late summer and fall. Mazur pointed out that the weeds are primarily natives and the higher lake levels help in respect to fishing. Mazur added that conifers should be planted along the lake to replace the trees that were lost over the years, because shade improves fish habitat as well as the downed trees.
d. Lake Management Plan development - Dr. Mark Sytsma, of Portland State University Center for Lakes & Reservoirs lead an informal discussion with the group. Sytsma stated that his staff have visited and done sampling of the lake, but his last visit was about ten years ago. He noted that when he last visited, the Eurasian Milfoil was rampant around the 12th Street Boat Ramp and was pleased that he did not see any today. Sytsma referred to some of the items on the “Facts Sheet”, and pointed out that the areas within the 16 foot depth range are ideal for many plants. He said his method to management/funding is generally to use DEQ for planning funds and ODA for aquatic weed abatement funding. Sytsma acknowledged that Garrison Lake has drawn the interest of DEQ, but their general stand is “wait a couple of years for the ecosystem to stabilize” prior to designing a management plan. Discussion around Garrison Lake not being on the DEQ list of critical water bodies. Sytsma said the lake waters should be sampled for pH (by probing) and for chlorophyll this summer, to establish current water quality. Myers said the sampling tools were available, but funding was an issue. Sytsma added that noxious weeds are also a category that would move the lake into “water quality issues” status, but it does not seem to be a current problem. Sytsma’s team has been working on the Siltcoos Lake, which had toxic algae blooms and is a drinking water source. He explained that those issues qualified Siltcoos Lake to just make it on to the bottom of the DEQ list. McQuade brought up the “tules” expanding their area around Garrison Lake. Sytsma pointed out they do provide fish habitat, but could be addressed through site management (such as clearing paths for boat access). Sytsma suggested that the group review documentation on the website for the Center for Lakes and Reservoirs, http://www.clr.pdx.edu/. He said there is a step by step plan on vegetation management, covering the three methods of mowing, bottom barrier, and chemicals. Sytsma mentioned that mowing could be hired from a TenMile Lake company. Myers pointed out that excavating to remove weeds is not allowable. Mazur clarified that excavating a 50 cubic foot area is permitted on some waters, but not Garrison Lake. Sytsma suggested that the group look at the detailed management plans posted on the website. He summarized with “you have to choose the problem to address, the whole lake is not the problem”, adding that he prefers to create site specific management plans. Miller asked if Sytsma would consider scoping a management plan. Sytsma said he will talk with Pam Blake of DEQ and discuss more details with Cindy Myers. (Note: 6/19 am - He toured the lake on John Leuthe’s boat and retrieved some plant samples)
e. Open topics for discussion -
Water sampling c/o Surfrider through the P.O. Ocean Resource Team: McQuade summarized the foundation’s efforts, including the March Water Festival and ongoing water testing. McQuade explained how water samples have recently been taken from Mill Creek, the exit of Mill Creek, and the lake water approaching the outflow. He stated that the findings showed 20ppm, 30ppm and 100ppm of enteroccocus respectively (advisories are issued at 150ppm of these bacteria). Additional samplings will continue through summer. Miller added that the warning decals have been applied to several entrances to the storm drains, a project of the POORT.
DEQ testing of beaches: Myers briefed the group on beach water sampling taking place, which is expected to include Hubbard Creek. She stated that Surfrider wants to recruit additional volunteers for sampling and Jared Tarr is the contact (332-1032).
Oregon Water and Wastewater Infrastructure Finance Summit: Nowlin distributed a flyer for this summit on July 17th at the Oregon Garden Resort, Silverton. Chris Marko, Rural Community Assistance Corporation, is a key contact.
