RVCA uses the data to supplement that from EC climate sites. ‐ RVCA has six precipitation monitoring sites in field locations in the upper half of the Rideau watershed equipped with heated tipping bucket gauges. Installation of telemetry is pending and the data will be used as mentioned in the previous point. ‐ Data from fifteen Provincial Groundwater Monitoring Network stations and several nearby in neighbouring watersheds are beginning to be used in drought analyses. ‐ Twenty Onset Hobo pressure transducer loggers have been deployed in streams and lakes throughout the watershed recording water levels and water temperatures. The intention is that the data will be accumulated for an extended period (>10 years) to be used to characterize the variations that occur in each of these waterbodies for both biological and hydrological analyses.

Municipal Drain Classification Program • The Municipal Drain Classification (MDC) System was developed by DFO, Conservation Authorities and other partners to strike a balance between the requirements of the Federal Fisheries Act and the Provincial Drainage Act by streamlining the review and approval process related to impacts of drain maintenance activities on fish habitat. • There are six drain types that result from the assessment (Type A, B, C, D, E, F) and each type has varying sensitivities with respect to drain maintenance work. • Assessment of: flow type, temperature, fish species, and aquatic habitat conditions. • RVCA has a total of 415 municipal drains across the watershed Ontario Benthos Biomonitoring Network • Goal: to determine water quality and habitat quality using a biological method which compliments water chemistry sampling programs, the OBBN protocol samples bottom dwelling bugs (benthic invertebrates) • 48 stream sites in the spring and fall and 2 lake sites in the spring • Sampling is done using a standard kick and sweep method with a D‐net • Three replicates are collected at each sample location; they are preserved and brought back to the lab for identification • Samples identified to the family level and several indices are run to assess water quality and overall aquatic habitat health Headwater Monitoring Protocol • Goal: to provide standard datasets to support science development and monitoring for headwater drainage features • RVCA is working with TRCA and MNR to develop and implement the protocol which measures zero and first order headwater drainage features • A rapid assessment method characterizing the amount of water, sediment transport, and storage capacity within headwater drainage features (HDF) • This protocol also characterizes the connectivity, form, and unique features associated with the HDF • 600 sites sampled by RVCA staff from 2011‐ 2014 Headwater Monitoring Field Work • Sites are sampled at road crossings • Various parameters are measured including the following: – Flow measurements upstream and downstream of the water crossing – Feature type (natural, wetland, channelized, braided, buried, swale, roadside ditch, on line pond, etc) – Sediment transport and volume – Riparian vegetation – Site features (nutrient sources
