2017 Reports
Beltrami County Summary Report 2017
Overall, the lakes in the county are in great shape. Most are stable or improving in water quality. There were just 2 lakes found to have declining trends, Big and Turtle River lakes. It is not clear; however, what could be causing these trends. They could be naturally caused. See the Beltrami County Summary Report pages 17-20 for a prioritization and recommendations for lakes.
Andrusia_04-0038-00
Comments: Improving trend in transparency. Protection focus.
Balm_04-0329-00
Comments: No concerns. Protection focus.
Beltrami_04-0135-00
Comments: No major concerns. Protection focus.
Bemidji_04-0130-00
Comments: No trends, so water quality is stable. Protection focus: reduce stormwater from City of Bemidji into the lake and Miss. River.
BigBass_04-0132-00
Comments: No trends. Protection focus: reduce future additions in impervious surface.
BigTurtle_04-0159-00
Comments: No trends. Protection focus.
Big_04-0049-00
Comments: Declining Secchi trend. It is difficult to determine what could be causing this trend, but monitoring the inlet, monitoring for internal loading, and evaluating the shoreline development could provide clues. Or it could be a naturally-caused trend as well.
Black_04-0157-00
Comments: No trends. Protection focus.
Blackduck_04-0069-00
Comments: No trends, but it is possible that internal loading is still occurring from the legacy phosphorus at the bottom of the lake from the City of Blackduck’s wastewater before the 1980s.
Campbell_04-0196-00
Comments: Shallow lake. No concerns.
Cass_04-0030-00
Comments: No trends; no concerns.
Dark_04-0167-00
Comments: No trends; no concerns. Very interesting lake! Only 75 acres surface area, but 120 feet deep.
Deer_04-0230-00
Comments: No trends; no concerns.
Fox_04-0162-00
Comments: No trends; no concerns.
Grace_29-0071-00
Comments: No trends. There could be some internal loading of phosphorus from the lake sediments occurring as well, but the lake is not showing a declining trend in water quality, so it could be that internal loading levels are the same as they’ve always been.
Grant_04-0217-00
Comments: No concerns.
Gull_04-0120-00
Comments: Shallow lake. First tier is fairly heavily developed, but there is a stable clarity trend.
Irving_04-0140-00
Comments: Impaired and 40% developed in lakeshed. The TMDL is complete and referenced in this report.
Julia_04-0166-00
Comments: No trends; no concerns.
Lindgren_04-0153-00
Comments: Completely protected by state forest. Weak evidence of an improving trend in transparency.

Comments: No trends; no concerns
LittleTurtle_04-0155-00
Comments: Impaired waters list. The TMDL is complete and referenced in this report.
Long_04-0076-00
Comments: Improving trend.
Long_04-0227-00
Comments: Well protected; no immediate concerns.
Marquette_04-0142-00
Comments: No trends; no major concerns, but watch development in the area and monitor the Schoolcraft River.
Medicine_04-0122-00
Comments: No trends; no concerns.

Comments: Improving trend; no concerns.
ThreeIsland_04-0134-00
Comments: No trends; no concerns; well protected.
TurtleRiver_04-0111-00
Comments: Increasing phosphorus, but could just be due to large watershed.
UpperRedLake_04-0035-01
Comments: No trends. MPCA modeling shows that 70% of the P loading is from atmospheric deposition and groundwater.
WhiteFish_04-0137-00
Comments: Improving transparency; well protected; no concerns.
