5.29 Goose Lake Watershed Management Plan

5.29.1 General Information

Goose Lake is west of Keats Avenue

North (CSAH 19) and on both sides of

10th Street North (CSAH 10), in the

City of Lake Elmo. Approximately

six acres of the 38-acre lake are located

north of 10th Street North. The

remaining 32 acres is south of 10

Street North. An unknown sized culvert

connects the two lobes of the lake,

referred to as Goose Lake North and

Goose Lake South. The Goose Lake

watershed lies entirely within the City

of Lake Elmo (see Figure 5.29-1).

Current land use in the Goose Lake

watershed is primarily residential, with

some agricultural land use in the

western part of the watershed. A large

residential development (Stonegate),

representing about 30% of the tributary

watershed, was constructed in the mid-

1990s west of Goose Lake South. Other

single-family residential developments

(Whistling Valley first, second, and

third additions) have been under

construction since the mid-2000s

around Goose Lake North. As of the

writing of this Plan, another residential

development (Hammes) is being

constructed south of Goose Lake South.

Future estimated land use in the Goose

Lake watershed includes a combination

of single family-residential and large-

lot residential land use, as well as some

park and recreation land use. Current

(2010) and estimated future (2030) land

use is presented on Figure 5.29-2.

Goose Lake is considered a picturesque

lake, and is primarily used by area

residents for aesthetic viewing purposes. The lake has been used to a lesser extent for fishing. A

private fishing dock was constructed on the north lobe of the lake in 2003 as part of the Whistling

Valley development. As of the writing of this Plan, the City of Lake Elmo is consideration

constructing viewing access in the southeast corner of Goose Lake South, The VBWD anticipates

that recreational use of Goose Lake will increase with the development in the area. Currently, there is

no official public access to either Goose Lake North or Goose Lake South.

5.29.2 Water Quality Management Plan

The Minnesota Pollution Control Agency (MPCA) classifies the north and south lobes of Goose Lake

as separate waterbodies. Goose Lake South is classified as a shallow lake, while Goose Lake North is

not considered a deep or shallow lake due to its small area (less than 10 acres). Goose Lake South is

currently listed as impaired for aquatic recreation by the MPCA due to nutrients, eutrophication, and

biological indicators, and is included in the MPCA’s 303(d) impaired waters list because of excessive

nutrients. Goose Lake North is not listed as an impaired water because it is not classified as a shallow

lake.

The VBWD classified Goose Lake as a High Priority waterbody according to its waterbody

classification system (see Section 4.1 – Water Quality), due to the inclusion of the south lobe of the

lake on the MPCA’s impaired waters list (see Table 4.1-4). Historically, Goose Lake has had poor

water quality. The VBWD previously classified Goose Lake as a Level III water body in the 1995

VBWD Water Management Plan and a low priority waterbody in its 2005 Plan.

The VBWD has a non-degradation water quality policy which sets “action triggers” for all of its

major waterbodies. Section 4.1 – Water Quality discusses the action triggers in more detail. Action

triggers for VBWD lakes consider the following water quality parameters (summer average) relative

to MPCA water quality standards and prior water quality data (i.e., trend analysis):

 Secchi disc depth

 Total phosphorus

 Chlorophyll a

Specific water quality implementation tasks for Goose Lake include the following:

1. The VBWD will cooperate with other entities to monitor the water quality of Goose Lake and

perform the actions discussed in Section 4.1 – Water Quality for High Priority water bodies.

The VBWD may conduct more intense monitoring of the lake as needed based on actions

recommended in Table 4.1-6.

The VBWD will evaluate the average summertime water quality (total phosphorus,

chlorophyll a, and Secchi disc transparency) and compare it to applicable water quality

standards (Table 4.1-1) and applicable action triggers (described in Section 4.1.7.5). Based

Barr Engineering Company Page 5.29-3

P:\Mpls\23 MN\82\2382174\WorkFiles\2015 VBWD Plan\Final\Section 5.29 - Goose Lake.doc

on Table 4.1-6, the VBWD may perform Survey Level plus Supplemental Water Quality

Monitoring, as necessary.

2. The VBWD will consider implementing the following actions to improve water quality in

Goose Lake:

a. More intense monitoring to better estimate how much phosphorus is entering the lake,

and ultimately, determine the feasibility and cost-effectiveness of improvement

options identified in this Plan or subsequent studies.

b. Evaluating the feasibility of enhanced treatment and small scale stormwater BMPs

within the watershed tributary to Goose Lake. The VBWD’s BMP cost-share program

may provide opportunities for private landowners to implement water quality

improvements. Collectively, many small residential BMPs may have a significant

impact on the cumulative phosphorus loading to Goose Lake.

c. If necessary, the VBWD will cooperate with the MDNR and others to reduce internal

loading in Goose Lake. This may include an in-lake aluminum sulfate (alum)

treatment of Goose Lake. In-lake alum provides a long-term control of the

phosphorus release of lake sediments (see Section 4.1 – Water Quality). An in-lake

treatment could be effective for up to ten years, depending upon how well the

watershed nutrient sources have been reduced. When alum is applied to shallow

lakes, the improved water clarity usually results in increased (and often undesired)

aquatic plant growth. This can be exacerbated by the presence of aquatic invasive

plant species. The VBWD will need to consider improved water clarity versus

increased aquatic plant growth before moving forward with alum application projects

on these lakes.

d. Management of macrophytes (aquatic plants) of the lake. Treatment of areas

containing dense, monospecific growths of invasive species with an aquatic herbicide

(2,4-D, Triclopyr, or low concentrations of Aquathol® K) is recommended to protect

Goose Lake’s native plant community. The VBWD will cooperate with the City of

Lake Elmo or other entities in support of macrophyte management efforts. VBWD

efforts may include

 point-intercept surveys of aquatic vegetation

 preparation of lake vegetation management plans (LVMP)

 completion of Invasive Aquatic Plant Management (IAPM) Permit

applications

 design of herbicide treatment programs

 participation in meetings with MDNR staff

 other technical analysis

3. The VBWD will cooperate with the MPCA to participate in any required total maximum

daily load (TMDL) study and TMDL implementation plan for Goose Lake South. This may

include collaboration with Municipal Separate Storm Sewer System (MS4) permit holders

(e.g., City of Lake Elmo, Washington County, etc.) to meet wasteload allocations determined

by the TMDL study.

4. The VBWD will consider collecting sediment core samples from Goose Lake to assess the

potential for internal phosphorus loading from sediments.

5. The VBWD will continue to implement its Rules and Regulations (2013, as amended) in the

Goose Lake watershed. The VBWD Rules address water quality performance standards for

development and redevelopment projects, as well as required vegetated buffers around

VBWD lakes, streams, and wetlands. The VBWD Rules and Regulations are included in this

Plan as Appendix A-4.5.

5.29.2.1 Water Chemistry Data

Water quality sampling has been conducted on Goose Lake once in 1959, 2003, and annually since

2008. Water quality samples are typically analyzed for total phosphorus and chlorophyll a, while

Secchi disc transparency is measured in the field at the time of sampling (see Appendix A-4.1 –

Water Quality Background Information). Water quality samples are collected in both the north lobe

and the south lobe of the lake. Goose Lake North and Goose Lake South are considered as separate

waterbodies for computing water quality averages and trends.

The most recent 10-year average summer water quality data for Goose Lake North and Goose Lake

South are presented relative to applicable MPCA and VBWD water quality standards in Table 5.29-1

and illustrated in Figure 5.29-3 (Goose Lake North) and Figure 5.29-4 (Goose Lake South).

P:\Mpls\23 MN\82\2382174\WorkFiles\2015 VBWD Plan\Final\Section 5.29 - Goose Lake.doc

The 10-year averages of summer average total phosphorus, chlorophyll a, and Secchi disc

transparency in Goose Lake South all exceed (i.e., are worse than) the applicable water quality

standards (Table 5.29-1). Summer average total phosphorus, chlorophyll a, and Secchi disc

transparency exceeded the applicable standards in all 6 years sampled between 2003 and

2013.Maximum (i.e., worst) summer average phosphorus and chlorophyll a concentrations and

minimum (i.e., worst) summer average Secchi disc transparency occurred in 2009. Comparatively, in

Goose Lake North, the worst summer average total phosphorus and summer average Secchi disc

transparency occurred in 2010.

Water quality has steadily improved in Goose Lake North since 2010 and in Goose Lake South since

2009, although no statistically significant trends are evident. The lowest (i.e., best) summer average

total phosphorus and summer average chlorophyll a values occurred in 2013 in both lakes.

5.29.2.2 Other Water Quality Issues

In the mid-2000s, the VBWD was made aware of a ravine erosion issue on the west side of the north

lobe of Goose Lake. In 2007, the VBWD evaluated the stability the eroding ravine adjacent to Goose

Lake. After holding a public hearing on August 28, 2008, the VBWD Managers ordered a project for

stabilizing the ravine on the north lobe of Goose Lake. By the end of 2008, the VBWD’s contractor

had completed most of the work to stabilize the Goose Lake ravine. In 2009, trees and shrubs were

planted at the ravine site (following a cover crop seeding in 2008). Since the project, erosion at the

ravine as continued. The VBWD’s consultant has visited to the site several times document the issue

and will prepare a recommendation in 2015 to address the ongoing erosion issues.

Developers of the Whistling Valley residential development installed an aerator in Goose Lake North

at the time of construction. Aeration may reduce the potential for anoxic conditions that drive the

release of phosphorus from lake sediments. The VBWD has not quantified internal phosphorus

loading in Goose Lake. Aeration may also benefit the Goose Lake fishery by increasing dissolved

oxygen levels.

5.29.2.3 Biological Data

Various types of biological data have been compiled and evaluated for Goose Lake, in addition to

physical and chemical parameters. Macrophyte (large aquatic plant), phytoplankton (non-rooted

floating plants – algae), zooplankton (microscopic aquatic animals), and fisheries data provide

insight into the ecological quality of Goose Lake. Section 4.2 (Water Quality Background

Information) provides more information about the importance of fisheries and other biological data.

5.29.2.3.1 Fisheries Data

The Goose Lake fishery is not currently managed by the MDNR. No stocking or survey programs are

currently in place. Goose Lake does not have a fisheries-use classification and no fish consumption

advisories are currently in place for the lake.

The MDNR used the lake as a rearing pond from 1983 through 1989, and fish were removed for

stocking in other lakes. After 1989, the MDNR considered it no longer suitable for use as a rearing

2015 Valley Branch Watershed District Watershed Management Plan Goose Lake Watershed Management Plan

pond because of increases in the lake water level. The MDNR thought the lake would be suitable for

angling.

An MDNR fisheries survey was completed on August 13-14, 1959. Survey notes indicate the lake

had a surface area of 36.3 acres, a maximum depth of four feet, and a mean depth of two feet. An

algal bloom was noted, resulting in a Secchi disc transparency of less than 0.1 meters (3 inches). A

total alkalinity of 20 mg/L indicated the lake had moderately soft water. Fish noted in the lake

included fathead minnow, pumpkinseed sunfish, and largemouth bass. The lake was known to have

winterkilled in 1956, and is suspected to winterkill on a periodic basis.

The MDNR’s Lakefinder website includes the most current data for Goose Lake North and Goose

Lake South, respectively, available at: http://www.dnr.state.mn.us/lakefind/lake.html?id=82011301

and http://www.dnr.state.mn.us/lakefind/lake.html?id=82011302

5.29.2.3.2 Macrophytes (Large Aquatic Plants)

The VBWD conducted surveys of the macrophyte community in Goose Lake June 12, 2003, June 5,

2009, and June 5, 2012.

Appendix A-5.29 includes the Goose Lake 2003, 2009, and 2012 macrophyte survey information.

The VBWD collects macrophyte data to identify the conditions of plant growth throughout the lake.

Macrophytes are the primary producers in the aquatic food chain, converting the basic chemical

nutrients in water and soil into plant matter through photosynthesis, which becomes food for all other

aquatic life. While macrophytes can negatively impact the recreational use of a water body, they are

critical to the ecosystem as fish and wildlife habitat.

Goose Lake’s moderately diverse plant community consisted of seven to fourteen individual species.

Most of these species are common to Minnesota ponds and lakes and provide good habitat for fish

and aquatic animals.

Plant growth was generally restricted to a narrow fringe around the lake’s periphery. Growth

occurred to depths up to 3 feet deep in the north lobe and depths up to 2 to 3 feet in the south lobe.

Severe algal blooms in both basins throughout the growing season resulted in poor water

transparency (see Figure 5.29-3 and Figure 5.29-4). Shading by the lake’s algal community has

limited plant growth to the lake’s periphery.

The growth of two undesirable exotic (non-native) species in both basins of Goose Lake is of

concern:

 Curlyleaf pondweed (Potamogeton crispus)

 Purple loosestrife (Lythrum salicaria)

2015 Valley Branch Watershed District Watershed Management Plan Goose Lake Watershed Management Plan

Barr Engineering Company Page 5.29-7

P:\Mpls\23 MN\82\2382174\WorkFiles\2015 VBWD Plan\Final\Section 5.29 - Goose Lake.doc

Purple loosestrife was found along the south basin’s shore on all sides of the lake during the 2003 ,

2009, and 2012 surveys. Once a waterbody becomes infested with purple loosestrife, the plant

typically replaces native vegetation and rapidly becomes the sole emergent species.

Purple loosestrife can be effectively managed through the use of leaf-eating beetles, which reduce

plant growth and seed production by feeding on the leaves and new shoots. The VBWD may consider

partnering with the MDNR to introduce leaf-eating beetles to the purple loosestrife areas along the

lake’s shore to control purple loosestrife.

Curlyleaf pondweed (CLP) was found throughout the south basin’s periphery during June 2003, in

two locations, east and southwest sides of the lake, during August 2003, and at many points around

the south basin in June 2012. Plant densities were light to moderate during all surveys. Once a lake

becomes infested with curlyleaf pondweed, this plant typically displaces native vegetation, thereby

increasing its coverage and density. Curlyleaf pondweed begins growing in late August, grows

throughout the winter at a slow rate, grows rapidly in the spring, and dies in early summer. Native

plants that grow from seed in the spring are unable to grow in areas already occupied by CLP, and

are replaced by this plant. Elodea (Elodea Canadensis) and coontail (Ceratophyllum demersum),

species that overwinter, may limit curlyleaf pondweed increases in coverage and density in the south

basin of Goose Lake. Because CLP densities are light and overwintering native species may control

the spread of this plant, the proposed strategy for dealing with CLP in Goose Lake is monitoring its

population and instituting active management techniques only if its density or dominance of native

species becomes problematic.

5.29.3 Water Quantity

Goose Lake has a high overflow at Elevation 931.7 (1992 VBWD survey, NGVD29 datum). The

MDNR’s Ordinary High Water level (OHW) for Goose Lake is at Elevation 924.4 (NGVD29 datum).

At water levels above Elevation 931.7, water from Goose Lake will flow north in a ravine which

leads to Eagle Point Lake. Before Goose Lake reaches its overflow elevation, 10th Street North

(CSAH 10) would be inundated. The VBWD monitored Goose Lake water levels from 1972 to 1986,

and resumed monitoring in 2008. Figure 5.29-5shows the recorded water levels. Under normal

conditions, the culvert connecting the north and south lobes of Goose Lake maintains equal water

levels between the two lobes. The highest recorded water level of Goose Lake was 925.1 in July,

1978. Since resuming water level measurements in 2008, the highest observed water level was

Elevation 923.2, which occurred in the summer of 2014. Records from early 1975 indicate the lake

was dry. The VBWD 100-year flood elevation of Goose Lake is 932, just above its overflow

elevation of 931.7. The 100-year flood level was computed using the VBWD 100-year annual runoff

method. All homes surrounding the lake within subdivisions permitted by the VBWD were required

to have minimum floor elevations at least two feet higher than the 100-year flood level.

In 2013, the National Oceanographic and Atmospheric Administration’s (NOAA) published Atlas 14,

Volume 8 (see Section 4.7.6). Atlas 14 contains updated precipitation data for Minnesota. The

VBWD’s calculation of the Goose Lake 100-year flood level predates Atlas 14. Over the next several

years The VBWD plans to update the 100-year flood level for lakes, including Goose Lake, to reflect

2015 Valley Branch Watershed District Watershed Management Plan Goose Lake Watershed Management Plan

P:\Mpls\23 MN\82\2382174\WorkFiles\2015 VBWD Plan\Final\Section 5.29 - Goose Lake.doc

Atlas 14 precipitation data and other current data sources. These updates may result in an increased

flood level for Goose Lake.

VBWD has no plans to control water levels on Goose Lake.

5.29.4 Groundwater

Water that seeps from Goose Lake could contribute to the groundwater feeding Valley Creek.

Groundwater flow in Valley Creek is discussed in Section 5.20 of this Plan. Groundwater

management is more generally discussed in Section 4.2 of this Plan.

The Goose Lake watershed is within the Lake Elmo/Oakdale Special Well Boring Construction Area

(SWBCA). The Minnesota Department of Health (MDH) established this SWBCA after volatile

organic carbons (VOCs) and perfluorochemicals (PFCs) were identified in the groundwater. Section

4.2.6.3 includes more information regarding the Lake Elmo/Oakdale SWBCA.
