MPRB Commissioners vote 6-3 for reduced-pumping
Message from MPRB 5th Distict Park Board Commissioner, Steffanie Musich
"The Planning committee reviewed staff's water management recommendation at its July 19 meeting and voted unanimously to advance the proposal to the full board. The briefing provided to commissioners the meeting prior to the committee vote on this issue can be viewed here (the presentation begins 2.5 hours into the meeting and lasts for an hour and a half): https://cdn.qwikcast.tv/OrganizationFiles/Video/18/71217MPRB.mp4 The full Board of Commissioners voted 6-3 to pursue a reduced pumping water management plan for the course on August 9, 2017. The statement I made to my colleagues prior to our vote can be read here.
The MPRB, City of Minneapolis and Minnehaha Creek Watershed district have been examining the hydrological situation at Hiawatha since the violation of state water use rules was discovered during course renovation planning due diligence in 2015 following the flooding in 2014. A number of reduced pumping options were explored in hope that one would be identified that could preserve an 18 hole course on this site, no viable options were identified. Preliminary analysis did not identify a reconfigured 9 hole course with good play-ability that would align with the MPRB's golf strategy, which does not mean golf in some form on the site would not be considered by a CAC.
While a recent article in the StarTribune mentioned that the DNR would likely permit the park board to continue pumping at current levels, they noted that conditions would accompany that permit. One of those conditions is that the park board will need to begin implementing a reduced pumping scenario when the course floods again. As a steward of the land and resident's tax dollars, I did not see delaying the reduction of pumping until the next flood occurs to be a responsible decision for the long term sustainability of the park system and thus, voted to begin planning for a reduced pumping water management scenario.
A Community Advisory Committee will be convened in accordance with our public engagement policy to help determine future land use and water access within the areas that would be submerged/converted to wetland. Subscribing to project updates on the project page linked above will ensure you are notified of upcoming meetings and when the project page is updated so that you can help shape the future of this park land. Since the practice areas are primarily on high ground, I am hopeful that there may be enough community support for their preservation on the site as part of a new plan for the land in light of the long history of golf on this site. The course will continue to be operated as an 18 hole golf course while future site use is determined and necessary permits are obtained."

May 18, 2017 Meeting
Since the April 20 public meeting, staff and consultants have further evaluated options for water management and use of the Hiawatha Golf Course property. The range of options has been narrowed to two directions—one that maintains the current volume of pumping and retains the 18 hole golf course and one that reduces the volume of pumping while introducing other recreation activities to the property. Potential activities in a reduced pumping scenario draw upon input offered by participants at the April 20 meeting. A more detailed description of each option, including ecological, recreational, economic, and other factors will be shared at a public meeting to be held on May 18.

Lake Hiawatha Park planning and groundwater / stormwater pumping update - Attend the April 20 public meeting
The City of Minneapolis, Minnehaha Creek Watershed District, and the Minneapolis Park and Recreation Board are convening a public meeting to prepare for an in-depth park planning study related to the groundwater pumping and alternatives investigation for Lake Hiawatha.
At this meeting we’ll look at broad layout diagrams which generally illustrate the spaces created by the varying levels of groundwater pumping and how these layouts may affect certain uses within the park in the future. The majority of this meeting will focus on developing ideas for potential uses within the park. Meeting attendees will be split into random groups to develop their own ideas, and give a two-minute presentation so other groups can hear the ideas. This is an exercise to flesh out opportunities that may not already be realized
This work is closely related to potential impacts to nearby homes, as well as impacts that are more remote from the park but could be impacted by changes.
Please attend and let us know how you’d like recreate in your park!

The City of Minneapolis and the Minneapolis Park and Recreation Board (MPRB) are continuing work to investigate groundwater pumping and alternatives for Lake Hiawatha.The ongoing effort used data gained from monitoring devices installed more than a year ago to further understand the volume of water being pumped and other characteristics that might impact upon solutions that change pumping regimes.This work also more closely assessed potential impacts to nearby homes, as well as some that are more remote from the golf course but could be impacted by changes. MPRB and City Staff received a formal report on work completed to date during the week of Feb. 27 and will share that information publicly at a meeting on March 30.
Hiawatha Golf Course update 11/15/2016
Hiawatha Groundwater and Stormwater Pumping Update
Public meeting
Mon, Nov 29, 6:30 p.m.
Powderhorn Recreation Center (3400 15th Ave S)
On Wednesday, Nov. 2, Minneapolis Park and Recreation Board (MPRB) staff updated the Board of Commissioners on recent and upcoming activities related to the pumping of groundwater and stormwater from Hiawatha Golf Course into Lake Hiawatha. The update refreshed the findings presented to Hiawatha neighbors and the public in June. It also outlined the further investigations to be performed and frame decision points related to pumping scenarios. To facilitate the upcoming work, it is intended that technical assistance will be in place by early December and that work will proceed to a point where options can be fully described, including costs and implications, by July 2017.
As in the first stages of the exploration, the MPRB will be working closely with the City of Minneapolis Department of Public Works. Involvement of Public Works is necessary to fully understand the conditions and to frame a range of options to be considered. The MPRB and the City will engage other regulatory and partner agencies as we progress through Phase Two.
Key activities in Phase Two include investigations that support a full exploration of options related to pumping. While the general implications of two options—continuing pumping at current volumes or stopping pumping—were described in the June meetings, this stage of work will be more explicit in demonstrating the implications of those options and an option that reduces the volume of pumping. Each option may have varying impacts on the golf course, Lake Hiawatha and its water quality, nearby public infrastructure, Minnehaha Creek, and Lake Nokomis. Each may also have different effects on nearby private properties. By July, the requisite assessments and formulation of options will be complete and ready to be considered.
The outline of the second stage of investigations will be shared with neighbors and the public during a meeting scheduled for 6:30 pm, Nov. 29, 2016 in the Powderhorn Recreation Center gymnasium, located at 3400 15th Ave. S., Minneapolis.

Hiawatha Golf Course update 6/14/2016
Tonight's "Hiawatha Golf Course Improvements Project" meeting - Presentation & FAQ documents. The FAQ document gives a quick two page summary of the findings. No decisions about future actions have been made.
Hiawatha Golf Course update 1/27/2016
Minneapolis Park & Recreation Board release:
"The Minneapolis Park and Recreation Board (MPRB) is continuing its investigation of stormwater and groundwater conditions on Hiawatha Golf Course and the pumping of water from the golf course into Lake Hiawatha. In late November, the MPRB’s consultant installed monitoring devices at several locations on the golf course property to collect data related to groundwater conditions and to aid in measuring volumes of water pumped from the property into Lake Hiawatha. However, almost immediately upon installation of those devices Minneapolis experienced an unusual amount of rain, making the collection of truly representative data related to groundwater and stormwater data difficult. The MPRB’s consultant is using the data collected and "normalizing" it using historical records for rainfall and flows in Minnehaha Creek. Having sound data is critical in the calibration of groundwater and stormwater models that will demonstrate a range of scenarios with the pumps on or off.
Based on calculations performed by the MPRB’s consultants and using information from monitoring devices installed directly in the pumps, the MPRB believes the volume of water pumped from the golf course during monitoring to be generally aligned with information shared with the public last fall—which is representative of conditions when water levels in Lake Hiawatha are high.
In the last week, the MPRB’s consultant sampled water pumped from the golf course property into Lake Hiawatha. Analysis of the samples and comparison to other water samples regularly collected by the MPRB in Lake Hiawatha will take about four weeks. Understanding the quality of water pumped from the golf course is an important piece of information for the MPRB.
The work required to collect and interpret data means that the MPRB’s intention to share data is somewhat delayed. Information and initial conclusions will be shared once the MPRB has an opportunity to fully interpret the data and understand its impact on the golf course."

Information about Lake Hiawatha
On Wednesday, December 9, SENA hosted experts from the Minneapolis Park and Recreation Board, the Minnehaha Creek Watershed District & the City of Minneapolis to present to the community on the topic of lake health. Over sixty residents came to hear the presentation and participate in a discussion of the broad inputs that affect the health of the lake - some that are local, some that reach beyond the boundaries of the neighborhood.
A "Friends of Lake Hiawatha" start-up group will be meeting on Thursday, Dec 18th, 6:00pm at Angry Catfish Coffee (4208 28th Ave S) to discuss ways to address some ways to address lake-health issues in our neighborhood. Please stop by.

Meeting Update: Responses to resident questions
· Web page link to the City’s stormwater utility fee and credit process
Stormwater utility fee information and credit information can be found at: http://www.ci.minneapolis.mn.us/publicworks/stormwater/fee/index.htm
· Web page link to the MCWD dam operational guidelines
The Gray’s Bay Dam operating procedures can be found at: http://minnehahacreek.org/projects-capital-projects/past-projects/headwaters-control-structure-management-policy-and-operating
· Do we have any thoughts or control to change the cleanup event to earlier in the spring before all of the vegetation?
In the spring, there is more likely to be high flows in the creek which can create dangerous conditions for those collecting trash along or within the creek. In addition, we are more likely to have favorable weather, and therefore a better turn-out, if the event is held in the summer.
· Who knows anything about the University of Minnesota Carp Study and is this something that we should learn more about to benefit Lake Hiawatha?
MCWD Staff are working with the Sorenson Lab from the Minnesota Aquatic Invasive Species research Center (MAISRC) on a carp project within the MCWD upper watershed. MCWD and MPRB are partnered on a potential carp study in Lake Nokomis involving another carp researcher (pending grant funding). Both organizations are building knowledge of carp dynamics. It is not known if it is feasible to eliminate carp in the entire Hiawatha Watershed with current management practices. It was not thought to be realistically achievable in the 1998 Diagnostic Study.
· How do we find out if the golf courses draining in the Minnehaha Watershed are using Phosphorus on their courses? Are there actions that can be taken to reduce or eliminate fertilizer from that source?
MPRB’s Golf Foreman are the staff who are charged with caring for the turf at the Golf Courses, and decide on the types, rate, and timing of fertilizer application based on their professional knowledge and certifications. Fertilizer use at golf courses exists to supply essential nutrients to plants to achieve desired color, growth and pest resistance. As the demands on the turf are increased from lower mowing heights and increased traffic levels, additional fertility is needed to promote growth and turf recovery. Products that contain phosphorus can be applied by golf courses even when bans are in place. It can be applied if soil tests show it is needed for new growth, establishment, or for sod sewing.
In the case of the greens, small amounts of liquid fertilizer containing phosphorus are applied twice monthly during the golf season (for example, a 16-4-8 product at a 0.1 lb. rate). Foremen surveyed all used a liquid form of fertilizer on greens since it is taken up almost immediately (on the order of ~30 minutes) so the risk of phosphorus runoff is very limited due to the use of this type of product. Phosphorus is needed by the grass on the greens due to the traffic level and the very short mowing height.
Care of the turf on fairways and tee boxes is slightly different at each course, and several courses often do not need phosphorus-containing fertilizers on fairways due to soil conditions. At most, Foremen noted that a granular product containing phosphorus (15-4-8) was applied to fairways one time in fall in order to aid in spring green-up (for example, a 0.5 lb. N rate).
At Hiawatha Golf, in particular, the only phosphorus-containing fertilizers used in 2015 were: 2x per month small amounts of fast-absorbing liquid fertilizer applied directly to foliage on greens, and one granular application to fairways in Fall as noted above. Other courses in the MPRB system noted very similar use patterns, but varied slightly due to different soil types and local conditions.
Phosphorus use on courses managed by others in the drainage area aren’t known at this time. MCWD staff is going to continue having discussions on this.
· Question regarding cigarette butts and filters in the lake.
Cleveland Ohio is looking into community based solutions to reduce the stormwater contribution of cigarette butts (and cigarillos/swisher sweets etc.) that are washed onto beaches from storm sewers. Techniques developed in this project may be applicable to other cities. Info regarding a forthcoming Cleveland project:

Hiawatha Golf Course - Update 12/8/2015
Pumps temporarily shut off today as data collection continues
Meters were installed on the two six-inch pond outlet pipes discharging into Lake Hiawatha on Nov. 30. On Dec. 8, Barr Engineering will download the first full set of data collected from the pumps, transducers in the ponds and monitoring wells.
On Dec. 8 the pumps will be temporarily turned off, allowing water in the ponds to rise while measurements are made. The pumps will be turned on before water levels pose any risk to the golf course or surrounding properties. Data will again be collected once the pumps are turned back on.
The collected data will be used as the key inputs in a ground water model. A series of scenarios will be run through models with results available by the end of December. The MPRB and a consultant engaged to assess the validity of the models will spend several weeks reviewing the results of the various scenarios. Following that review, MPRB staff and consultants will prepare materials to share with the MPRB Board of Commissioners and the public.
Staff expects decision-making tools based on data collected to be in draft form by mid-January and materials will be ready to share publicly by the end of January. Key data and modeled results will inform decision-making, including definition of what happens when the pumps are turned off, particularly from the perspective of storm water flows, and an estimate of the annual volume of ground water pumped in current and future conditions.

Hiawatha Golf Course - Update 11/23/2015
Update on storm water and ground water assessment
Despite the wet weather conditions, most of the groundwater and surface water measurement equipment has been installed and is functioning at Hiawatha Golf Course. Minneapolis Park and Recreation Board (MPRB) staff and consultants are reviewing options to expedite the installation of the remaining measurement equipment.
Water levels at Lake Hiawatha, the ponds on the golf course, and Minnehaha Creek are high due to nearly four inches of rain in the last week. The pump station discharge lines are submerged in the lake. As a result of high water conditions, the installation of flow meters in the pump discharge pipes has been delayed. Depending on weather, the flow meters at the pump discharge pipes will be installed the week of Nov. 23.
Barr Engineering, the MPRB consultant on this project, installed three hand-driven piezometers southwest of Pond F and the instrumentation (a pressure transducer and data logger) has been installed. Piezometers are temporary vertical pipes driven about 5 feet into the ground and are used to monitor the groundwater level at that point. They are being used to monitor how groundwater levels fluctuate at the golf course in response to changes in pumping rates and changes in lake and pond levels. Data from the piezometers is being recorded but has not yet been collected.
Barr installed staff gauges and stilling wells in Lake Hiawatha, Pond D, and Pond F. Staff gauges are like vertical rulers that allow visual measurement of the water levels. Stilling wells are temporary vertical pipes installed in the water near the staff gauges. Electronic instrumentation is installed inside the stilling well to continuously record the water level and are intended to supplement manual measurements. Inside the stilling wells, waves are eliminated and the water surface is still, allowing for more accurate water surface elevation readings. The combination of the these two installations provide information on how Lake Hiawatha levels and golf course pond levels are related to groundwater levels and how changes in lake/pond levels affect groundwater levels and pumping rates.
Four monitoring wells have also been installed in various locations on the golf course to allow for measurement of ground water elevations. These are similar to the piezometers but they are deeper and are intended to be in-place for long periods of time. They are also constructed to allow taking of ground water samples from the wells. Instrumentation has been installed and water levels are being recorded. Water level data and water samples have not yet been collected.
The MPRB originally intended to measure stormwater flows into the golf course from the large storm pipe that drains into Pond A. These stormwater flows drain through the other golf course ponds and are then pumped into Lake Hiawatha. Barr’s work discovered the large storm sewer pipe contained significant accumulations of sediment, and efforts are underway with the City of Minneapolis to remove the sediments so flow meters can be installed. Measurement of the stormwater inflow to the golf course helps to understand how much of the water pumped to Lake Hiawatha is groundwater and how much is stormwater. If sediments cannot be removed and the flow meter cannot be installed, Barr will perform calculations using the pump meter data to estimate the amount of stormwater pumped versus groundwater.
The MPRB is engaging Dr. Otto D.L. Strack as a peer review consultant to review Barr Engineering’s work once data is available for analysis. Dr. Strack is a professor of Civil and Geological Engineering at the University of Minnesota’s Civil Engineering Department and is an expert on ground water analysis and modeling of ground water flows. Dr. Strack’s review of investigations and conclusions is important to the MPRB because of the potential impacts to the golf course and surrounding private properties should pumping conditions change.
In October, the MPRB applied for a ground water appropriation permit from the Minnesota Department of Natural Resources (MnDNR). Communications with the MnDNR are continuing to ensure all necessary information supporting the permit application is provided. When the MnDNR considers the permit application complete, the MPRB will be invoiced for the permit. However, the DNR has indicated it will wait for the results of the Barr work to fully review the permit application.
Despite the wet weather conditions, most of the groundwater and surface water measurement equipment has been installed and is functioning at Hiawatha Golf Course. Minneapolis Park and Recreation Board (MPRB) staff and consultants are reviewing options to expedite the installation of the remaining measurement equipment.
Water levels at Lake Hiawatha, the ponds on the golf course, and Minnehaha Creek are high due to nearly four inches of rain in the last week. The pump station discharge lines are submerged in the lake. As a result of high water conditions, the installation of flow meters in the pump discharge pipes has been delayed. Depending on weather, the flow meters at the pump discharge pipes will be installed the week of Nov. 23.

Hiawatha Golf Course - Update 9/15/2015
Minneapolis Park & Recreation Board release:
"Hiawatha Golf Course Improvement Meeting
Posted on September 15, 2015
On Friday, September 11, 2015, staff of the Minneapolis Park & Recreation Board (MPRB) and the City of Minneapolis Department of Public Works reviewed new, preliminary information regarding groundwater at Hiawatha Golf Course. This initial data, collected as part of a report expected to be presented to the Park Board and City in November, suggests that the groundwater volume is greater than previously understood and may pose limitations for the concepts prepared for review at the Lake Hiawatha Golf Course improvement public meeting scheduled for 6 pm today, Tuesday, September 15 at the Lake Nokomis Community Center.
The preliminary data indicates that substantial amounts of groundwater are being pumped from areas of the golf course each year to maintain the course in a playable condition. The exact amount has yet to be determined; however, initial calculations estimate up to 273 million gallons per year. The preliminary information received indicates that without the pumps, groundwater may overwhelm the course. As this preliminary data is new, its implications and impacts have yet to be understood. Once the report is presented to the Park Board in November, it will take MPRB staff several months to fully review the report and reach conclusions related to the reconfiguration of the golf course.
While the MPRB regrets that this information is coming so late in the process, it is a result of the due diligence being pursued by the MPRB and its partners in the Hiawatha Golf Course study. Only after the report is fully assessed can a series of recommendations be reviewed with the community and golf stakeholders. Rather than cancel tonight’s meeting, the MPRB chose to share this new information with attendees and answer questions as staff is able."
The MPRB will be further gathering data around this groundwater issue, and will share its findings at a future meeting, likely 3-4 months from now.
