Description Lake Whatcom is impaired for dissolved oxygen due to phosphorus loading. Lake tributaries also fail to meet fecal coliform bacteria standards. Ecology conducted this technical study to set Total Maximum Daily Loads (cleanup plans) for these pollutants.

Based on 2002 and 2003 data, a CE-QUAL-W2 lake model and an HSPF watershed model were developed. Land uses in the watershed model were adjusted to evaluate Lake Whatcom’s response to phosphorus. Loading capacities for total phosphorus and for developed acres were calculated to protect dissolved oxygen in the lake.

Bacteria levels in 11 tributaries did not meet standards. Bacteria concentration and reduction targets were calculated.
