Algae blooms in the South Branch

We reported these alga to Potomac Riverkeeper. Algae typically blooms in periods of excess nutrients. In the South Branch, that often happens here in mid-August after a rain following long arid periods due to runoff from farms.

Surprisingly, many cattle farmers still allow their livestock in the river, despite many available, well-funded programs to help farmers be responsible in protecting watersheds. Manure management, particularly at large poultry operations is another source of excess nutirents.
