Tamarack Lake is located in the city of Victoria. Head east on Minnetonka Blvd and turn right at Co Rd 101. Turn right on MN-7 and then take a left onto Rolling Acres Rd. Turn left onto Tamarack Trail and then to access Tamarack Lake take the trail system heading east.
Most of the surface area of Tamarack Lake is littoral zone (shallow area between 0-15 ft) which is overrun with aquatic vegetation. Tamarack Lake was enrolled in the CAMP program in 2001. Secchi disk depth data is available from 1985 while water quality data (including secchi disk depth) is available in the STORET database starting in 2001. Currently, the citizen-assisted lake monitoring program (CAMP) monitors on a bi-weekly basis and sends the data to the Metropolitan Council staff. MCWD receives the raw data each fall (Met Council, 2007).
Currently not available.
Monitoring season started in late April and ended in late September by CAMP. Surface water samples were collected and analyzed for a variety of parameters, but MCWD is concerned with chlorophyll-a and total phosphorus (TP). Secchi disk depth was also recorded.
| 2008 Summer Water Quality Summary |
| Parameters | Range | Mean | TSI Value | Lake Grade |
| Months | June - Sept. | May - Sept. | ||
| Secchi Depth (m) | 1.8 - 4.3 | 2.8 | 45 | B |
| Surface TP (µg/L) | 19 - 33 | 24.7 | 50 | B |
| Chlorophyll-a (µg/L) | 2.8 - 20 | 9.3 | 52 | A |
| Overall Score | 49 | B+ |
The following summary refers to Figure 6.7 (a-c).
- Secchi disk depth increased from 2.3 m to 4.3 m from late April to early June. From the middle of June to the middle of August secchi disk depth remained consistent between 2.4 m and 2.7 m. By late September, secchi disk depth was 3.4 m (standard > 1.2 m).
- Chlorophyll-a concentrations decreased from 14 µg/L to 2.8 µg/L by early May. By early June, chlorophyll-a concentrations increased to 20 µg/L. The remainder of the season, concentration fluctuated between 9.6 µg/L and 12 µg/L (standard < 15 µg/L).
- Surface TP concentrations decreased from 75 µg/L to 19 µg/L by early May. The remainder of the season TP concentrations peaked twice: early June (33 µg/L) and early August (30 µg/L) (standard < 40 µg/L).
