Pollution is being discharged
directly into Bigfork Bay
There is ongoing and regular discharge of pollutants including oils, grease, sediment, heavy metals and fecal coliform bacteria entering the Swan River, Bigfork Bay, and into Flathead Lake from the Village area of Bigfork. These pollutants enter through Bigfork’s untreated stormwater system, and areas with inadequate stormwater containment, which carries nutrients and contaminants that are harmful to the ecosystem and the aquatic life of the lake. This discharge into Bigfork Bay, Swan River, and Flathead Lake threatens recreational activities and creates a potential hazard to human health and flood safety.
Pollution Verified
The testing of water quality in 1996 by the Flathead Biological Station in Bigfork Bay revealed that stormwater runoff from Bigfork contains high |
concentrations of fecal Coliform bacteria and other nutrients (specifically during the summer and fall precipitation events) that exceed EPA criteria for human contact and pose a public safety threat. In the subsequent ten-year period we can only surmise it has certainly become substantially worse. |

History
Neither Pacific Power nor Flathead County has installation records of the of the Bigfork stormwater system. Speaking with long time residents of the area, and the Bigfork Water and Sewer District (BWS), it is apparent that the stormwater system was installed before 1964, when the sewer system was built. The assumption is that the storm water system was installed in the mid-fifties at the same time as the water system for the Bigfork Village area. Four Corrugated Metal Pipes (CMP) empty stormwater and the pollution it contains directly into Bigfork Bay. Obvious drains, clean-outs, CMP’s and catch basins in the streets surrounding the Bigfork Bay have been located and noted. It is not known whether all are functioning nor where all these drains empty. However all ultimately do empty into the Swan River, Bigfork Bay and Flathead Lake. |
Today
The Bigfork Stormwater Project was initiated by the Flathead County Commissioners to update the Bigfork Stormwater System infrastructure. The decision to upgrade the system was made, in part, to control minor flooding in Bigfork caused by undersized stormwater conveyance pipes. Another factor in the decision was the large volume of unfiltered water containing pollutants, nutrients and fecal coliform bacteria that the stormwater system regularly delivers to Bigfork Bay.
Early in the project the Flathead County Commissioners selected citizen members to serve on the Bigfork Stormwater Advisory Committee (BSAC) to provide to them recommendations related to the project. One of the first steps for the project was to develop a Preliminary Engineering Report (PER). A second engineering assessment was completed in December 2009 by 48 North Civil Engineering, which focuses on changes in stormwater flow from school property and a more in-depth study of the Bridge Street area south of Bigfork Bay. The Bigfork Public Schools have installed two detention and filtration systems (2008 & 2009) and five additional dry wells on school property to reduce the amount of stormwater reaching the conveyance system on Grand Drive. The public is welcome to attend any regular BSAC meetings held the last Wednesday of each month, 12:30 p.m. at Bethany Lutheran Church or contact Chairman, Sue Hanson, at 837-5323 or email: btrfly@montanasky.net.
CURRENT STATUS
Phase I Grand Dr.
FAQ's
When will construction begin? Not until after Labor Day. Start date is contingent on final design, approval by funding agencies, bidding process, contractor selection and weather.
Will Grand Dr be completely blocked off? No. For public safety, one lane will be open at all times.
Who do I contact if there are problems? Construction schedule will be posted on the website (www.bigforksteering.org/Stormwater) with a 24 hour telephone line and other contact information. A volunteer will also walk the project daily to check in with business owners. There will also be information posted with the Bigfork Chamber of Commerce. You may also contact:
48 North Engineering, 756-4849 (Brett Walcheck or Jim Williamson)
BSAC Chairman, Sue Hanson 837-5323
Commissioner Joe Brenneman, 314-0075 (cell) or 758-5508 Commissioner’s Office
What type of system will you install? The conveyance lines along Grand Dr. will be replaced or upgraded. Four Filtera (www.filtera.com) units will be installed along Grand Dr. for pre-treatment of phosphorous, nitrogen and other nutrients. On the Lake Street easement, on Grand Dr. a hydrodynamic separator (www.rinkerstormceptor.com/) will be installed to reduce suspended solids and oil. The stormwater flow will then enter the Imbrium Jellyfish unit (www.imbriumsystems.com/) which will filter stormwater through 20 cartridges before the treated stormwater is discharged into Bigfork Bay.
Will there be any infiltration of groundwater? No. All systems installed are self-contained and will not release any treated water into groundwater.
Will there be oversight of the contractor? Yes. The engineers from 48 North, BSAC members and a community volunteer will be on top of the project.
How is the project funded? Funding has been obtained through grants from DEQ, Treasure State Endowment Program, DNRC and in-kind donations.
Will all stormwater be treated? The water quality components of the Stormwater Systems are designed to treat the 2-year rainfall event.
When will other phases of the projects be completed? As funding is acquired. To complete the entire project, public funding will be required through a Rural Special Improvement District (RSID).

Outstanding Business 2009
Pictured L to R, Joseph Magaddino, Architect, Sally Bradshaw, owner of the Double Eagle, and Sue Hanson,
Chairman of Bigfork Stormwater Advisory Committee
Paul and Sally Bradshaw installed a detention and filtration system below the new construction of the Double Eagle in Bigfork Village. The design, suggested by architect, Magaddino, collects stormwater from the roof of the building which discharges into the detention area. The patio of the new building utilizes pervious pavers to filter water
from the entry into the collection area beneath the building.
The system is designed for a 10 year event.
MINUTES
May 26, 2010 Notes of
Bigfork Stormwater Advisory Committee
48 North Work Session
1:00 p.m. July 1, 2010
DRAFT
Opened meeting at 1600.
Present: Joe Brenneman, Tom Weller, Sue Hanson, Lamont Kinkade, Paul Rana, Debbie Pierson, Dave Prunty, Jim Williamson, Brett Walcheck.
Brett and Jim discussed the alternates to Grand Drive and connection to River Street stressing that under the current funding cycle we were only considering Grand drive.
There are no systems planned for storm water mitigation on Grand Dr. that INFILTRATE to the soil. All are closed systems.
Four Filterra units (filterra.com) will be the 1st course of treatment along Grand to filter phosphorous, nitrogen and metals, which bind to soil (approximately 40%). Trees, shrubbery or grasses will be planted in the Unit as a means of nutrient uptake.
The South side of Lake Ave will have the Stormceptor system (rinkerstormceptor.com), a hydrodynamic separator, to remove sediments (suspended solids) in stormwater runoff before passing into the larger system. The Stormceptor system also traps oil, which can be removed by a vacuum process during maintenance. About 74% of the annual runoff per year can be treated by this system. The unit is approximately 6’ in diameter and 8 to 9’ deep.
Stormwater runoff then enters the Jellyfish system (imbriumsystems.com), which filters to 4 microns. The Jellyfish, in conjunction with the Stormceptor system, will be able to treat 86% of all yearly runoff. This equates to 100% of stormwater flow 80% to 90% of the time. The unit is approximately 14’ in depth. There are expenses and maintenance that come with both of these systems.
A 'hydrodynamic device" is a device that uses moving water as the main source of propulsion and activation. There are many brand names and "nick names" for the devices such as Stormceptor and Jellyfish, but in the basic explanation they are all hydrodynamic devices. Both systems have no moving parts.
Jim stated the objective of the system as the treating of "runoff". Jim also spoke about the "first flush" concept in conjunction with the peak event graphs. Yellow Bay Biological Station rainfall data was used as opposed to Glacier Airport, considering it was the most conservative design approach for more accurate to rainfall in the Bigfork area. “NOAH” was the data source considered by 48 North to be the most conservative. more accurate.
The western edge of the system on Grand Dr. will begin approximately at the entrance to Marina Cay. The treatment systems on Lake St. are designed to also treat stormwater to be later connected from the River St., northern section of Electric Avenue and Grand Dr. east of Lake St.
Debbie stressed the actual timing of events for the bid process, given the level of funding for this first phase. Final engineering must be approved by DEQ and TSEP before the bidding process can begin.
Meeting adjourned at 1830.

1230: Meeting opened by Sue. A quorum was deemed present and the meeting was called to order. The agenda for this meeting was approved unanimously.
1233: Minutes from the 26th of May meeting were accepted.
1234: Lamont described the advantages of the various types of placards for storm water inlets. Topics of discussion were size, shape, costs and modifications. Time table that the supplier has for production was also discussed. Lamont suggested that he order a supply of placards and donate to the committee as In-Kind contribution from the community. He will investigate further as some wording may cause a change in unit costs for the placards. Committee thought the oval shape might catch more attention. Lamont will investigate the price.
1250: Several guests offered insights about the construction times/days specifically. Both Neil and Brad expressed concern about the degree of notification of businesses along Grand Avenue during past construction projects. Several suggestions were made regarding weekend work and night work hours. Dave suggested that all concerns will be negotiated when the contractor and the engineers discuss the actual timing of the project. Tom suggested that contract can be written with these sorts of concerns accounted for. Christensen suggested 1) Committee hold a construction contract work session, 2) Pre-bidding meeting, 3) Pre-construction meeting with contractor.
1312: The RLK Hydro letter to the Commissioners was discussed but tabled until the meeting with 48 North on 01Jul10.
1317: Sue Sutherland discussed the tentative agenda for the summer workshop. The date of the workshop was determined to be Saturday, 11 Sept 10 and the times will be from 0900-1300. Discussion centered around display tables, donations from vendors, presentation times, and the use of the ARC (Bethany Lutheran Church activities hall). Lamont will further develop the theme of the workshop in conjunction with Sue S. Suggestion was “Flathead Lake - To Keep It Blue, It’s Up To You”. Kinkade will develop a logo for the Committee.
Incentives for participating were discussed and advertizing through the Chamber of Commerce newsletter and brochure production was suggested. Brad at UPS offered to donate a mailbox at UPS for registration. Food and catering are things that both Frank and Neil said they could consider helping with. Sue H will coordinate with Debbie Pierson to determine the best way to use NW Regional Resource Conservancy (Sue S) as a means by which funds can appropriately be distributed. The committee agreed that the Bethany Lutheran Church should receive a donation for the space that they give to the committee for routine meetings and for the workshops. Committee does not want to solicit sponsors. A fee of $50 was suggested for display tables for vendors.
1410: Discussion of the White Board outcome and the Strategic Plan was tabled until the next monthly meeting.
1413: Tom discussed the growth of the Flathead Stormwater Resource Group being headed up by the Whitefish Engineer, Karen Hilding. There are now more than 40 members from both Lake and Flathead counties. It was suggested that Flathead Lakers may be interested in a presentation for the FSRG.
1417: Tiffany offered a comment regarding the activities of the Boy Scouts in Bigfork and that there could be a possible role for them in the community education and outreach program. She will do some research and get back with Sue H. on the possible involvement potential of the BSA.

May 26, 2010 Minutes of
Bigfork Stormwater Advisory Committee
Bethany Lutheran Church
Members present: Sue Hanson, David Christensen, and Thomas Weller. Members of the public: Jasmine Linabary, Sue Sutherland, Julie Spencer, Edd Blackler.
The meeting was called to order at 12:35 p.m.
Agenda was adopted as presented.
Minutes of the April 28, 2010 meeting were approved.
OLD BUSINESS:
Inlet Labeling: Lamont Kinkade was not present to report on the inlet labeling at this time. Kincade has been asked to provide the number of decals necessary to label storm inlets throughout the Bigfork Planning Area. Per prior discussions, the decal is to be oval in shape and have language inclusive of “Drains to Flathead Lake”. Lamont has been asked to present to the Committee a firm cost proposal for review and approval of purchasing the decals.
Stewardship Awards: June 1, 2010 at 5:00 PM Russ Kinzer and the Bigfork School Board will be presented Stewardship Awards at the High School Library.
48 North: TSEP is stating it will only fund design and construction for Grand Drive, but not River Street. Flathead County has had conversations with the State Commerce Department & other agencies that “probably” funds could be released by TSEP to address River Street design and construction but no definitive understanding has been reached. 48 North has, at the request of the Committee, released the number of man-hours expended on the design thus far. This information was distributed by Sue Hansen to the remaining Committee members in attendance. Both Dave and Tom raised the question as to how the expenditure of hours relates to both the extent of design progress and extent of budget expended. Both Dave and Tom want to be clear that if 50% of the budget has been expended and the design plans are 50% complete. Deb Pierson and 48 North recently made a presentation to TSEP outlining the current funding strategy and where the various grant monies would be applied. The intent is to have the TSEP contract resolved and in place by the end of June 2010 to secure construction funding in time for fall construction. Dave and Tom will also attend the previously scheduled coordination meeting between 48 North and Sue Hansen to discuss design progress, and incorporation of “Basis of Design” comments. 48 North has suggested possibly omitting the new curb and gutter along Grand Drive prior to reaching MT 35 to avoid entanglements with MDT and preserve future funding options. It is being suggested by 48 North to post Construction Schedules and frequently asked public comments on the County website. Sue Hansen stated she would talk with Deb Pierson regarding the matter.
Public Meeting: Sue Hansen stated that over the course of time, requests come in for public information relative to the project, such as the PER and 48 North Assessment. This effort costs time and money. The Committee inquired whether the County could be the entity for exchange of money for services. A further inquiry was made whether the County has an ftp site to host larger files for public download such as the Supplemental PER prepared by 48 North. Sue Hansen stated she would make this inquiry. It has been asked that 48 North provide an explanation of the stormwater sampling results at the June 7th Public Meeting as both Mike Koopal and Tom Weller will be unable to attend. It was asked that all Committee Members be present at the Public Meeting on June 7th to help take notes and field questions. It was agreed that a video camera be provided to record events. Tom agreed to secure a video camera.
Sample Analysis: County Road Dept. swept streets but did not vacuum in the village prior to wash down. Workers, during wash down, were in front of the fire hoses scooping up debris and sediment where possible. Sue Hansen provided to the remainder of the Committee members present a copy of Mike Koopal’s latest pollutant levels collected during a recent, albeit light, rainfall event as well as during the street wash-down. The numbers showed very high levels of Zinc, TSS, and Phosphorus. There was concern that possibly the phosphorus numbers could be skewed by the fact that a water truck, provided by Saddlehorn LLC, may not have been thoroughly washed out prior to use. Discharge at the Public Dock showed high levels of foam. For the most part Village fire hydrants were used to supply the wash-down water. Julie Spencer of the Bigfork County Water & Sewer District (BFCWSD) stated her WWTP is constantly faced with abnormally high levels of Zinc, which is likely caused by stormwater infiltration into the sewerage system. This is a pollutant that is treated but at a cost as it passes through the WWTP. Sue Hansen asked that Julie quantify the additional costs burdened by the BFCWSD to address this matter. The intent is to use this information to gain further justification for grant monies and to educate the public as to financial impacts indirectly from stormwater pollution.
Stormwater Workshop: The Committee discussed what efforts need to be taken to jump start this summer’s public outreach workshop. The Committed asked Sue Sutherland of the Northwest Resource Conservation and Development (RC&D) to provide guidance and support for this effort. Ideas for consideration include; drivable lawns, pervious pavers, pervious pavement, DNRC’s Running Waters exhibit, a field trip to a riparian restoration project, etc. Booths and presenters need to be secured. A field trip with lunch provided is being considered. Time frame considered would be sometime in early September, on a Saturday, from mid-morning to mid-afternoon. The September timeframe is being considered to avoid the summer festival season and to focus on outreach to local residents. In 2008 25 people attended a similar workshop in Bigfork. The primary means of advertising for that workshop was via newspaper ads. Sue Sutherland of NRD&C suggested setting a date and then asking prior supporters, Flathead Lakers, et al, if they are available to provide funding, presenters/exhibitor, or both. The Committee felt contacting Oasis Consulting as a potential presenter/exhibitor. At the appropriate time, Tom will make that contact. Sue Sutherland and Sue Hansen agreed to meet in the near future to define responsibilities and outline direction for the public outreach workshop.
NEW BUSINESS:
White Board Summary: Dave Christiansen presented his revisions to the “Guiding Principles” for BSAC, which were well received by all present.
Given the timeline for the BFCWSD’s bond measure this fall, earnest pursuit of an RSID will be considered for the Fall 2011 to Spring 2012 timeframe.
PUBLIC COMMENT: The Committee asked RD&C if it were available to provide grant administration support to Deb to ease her workload. It was agreed the matter would be discussed further at the next meeting.
Meeting was adjourned at 2:35 p.m.
Upcoming Dates:
Public Meeting June 7, 2010
White Board June 18, 2010
Next Meeting June 30, 2010
