Biological impairment in Kansas reservoirs and lotic ecosystems due to erosion and sediment
In 2010 CPCB sampled Banner Creek, Centralia, and Atchison Lakes to quantify biological impairments and assess losses related to erosion and sedimentation. This is part of the Sediment Baseline work group effort that is coordinated by the Kansas Water Office. Banner Creek Lake has a lower sedimentation rate than the other two lakes and thus serves as a reference waterbody. At a limited number of sites in all three impoundments and the primary tributaries draining to each, we collected biological and physiochemical data including macroinvertebrates, velocity, in situ chemistry, TSS, VSS, TN, TP, and chlorophyll a. We will also evaluate habitat using the Habitat Development Index (HDI) and the Ohio EPA's Qualitative Habitat Evaluation Index (click and scroll to QHEI section).

Table 2. Number of samples in the lakes and their tributaries. One-liter water samples will be returned to the CPCB lab for processing of TSS, VSS, TN, TP, and chlorophyll a. Subsamples (surface, 15 cm, 30 cm and 1 m, if possible) of the lake core samples will be analyzed for particle size, bulk density and TP and TN.
