Minor watershed number(s): 28046
The project area was the Lake Crystal lakeshed of minor watershed 28046 which is in the Middle Minnesota River Major Watershed.
The Lake Crystal project was completed through the MPCA - Lake Assessment Program (LAP) in 1989. A LAP report includes general information about a lake's trophic status, factors (such as land cover/land use or point source pollution potential) affecting nutrient input to the lake, fisheries health, water quality, historical trend analysis, and watershed assessment modeling.

Surface Water Quality Monitoring
| Data Summary |
Lake Crystal - Lake Assessment Project (LAP) includes surface water quality data collected from two in-lake sites on five occassions during the 1989 sampling season. Analysis included total phosphorus, total kjeldahl nitrogen, nitrate/nitrite-nitrogen, chloride, suspended solids, total suspended inorganic solids, alkalinity, color, and turbidity. |

Watershed Assessment
| Data Summary |
Lake Crystal - Lake Assessment Project (LAP) includes data from a watershed assessment which used the Minnesota Lake Eutrophication Analysis Procedure (MINLEAP) model to assess the changes in the quality of the lake resulting from altered nutrient inputs or altered flow. This model incoprporates water quality, point source pollution potential, land cover/land use, and inflow and outflow data in its assessment. |
